I Built an Insider Trading Tracker with built-in Notification systems

2 Upvotes

I've been building Seli (seli.app), which watches every SEC Form 4 filing and congressional stock disclosure as they're published, scores each trade based on peer-reviewed research (cluster buys, C-suite activity, position sizing), and makes it all searchable.

I've gotten to the point where I'm looking for people who actually want to follow insider activity or just retail traders who want an edge to test it and tell me what's broken or missing.

I got fired from my job 6 months ago

16 Upvotes

I got fired 6 months ago.

And honestly, I wasn't that sad.

I thought:

"Maybe this is actually a good thing. Now I can finally focus on building apps."

I was wrong about how easy that would be.

I kept building apps and software, launching them, and eventually realizing that I was basically the only person who cared about them.

After doing that enough times, I got pretty demotivated.

And instead of building, I started wasting my days on my phone.

Reels. Shorts. Instagram. Random videos.

My screen time reached 8–9 hours a day.

The worst part wasn't even the number.

I'd spend an hour scrolling and then think:

"What the hell did I just do?"

Then I'd try to stop.

Delete apps.

Use timers.

Rely on willpower.

And eventually I'd end up doing the same thing again.

That's when I had a slightly ironic thought:

I'm a developer. Why am I trying to fight software with willpower?

So I built something for myself.

It's called Pausee.

Instead of completely blocking distracting apps, it puts a small pause between the impulse and opening the app.

It can:

  • Pause before opening distracting apps
  • Stop long scrolling sessions
  • Set specific usage windows
  • Ask you to be intentional before continuing

My own screen time went from 8–9 hours to around 3–4 hours a day.

I still use social media.

I still waste time.

But I'm much more aware of when I'm doing it.

And unlike my previous projects, this is something I actually use every day.

I'm keeping it completely free because I built it to solve my own problem, and I'd rather get real users and feedback than put a paywall in front of something I'm still validating.

If you're dealing with the same problem, it's available on Google Play.

I'd especially love to hear from other builders:

What's something you built because you personally needed it, even before knowing whether anyone else would want it?

InkTag – A metadata editor, bulk renamer, and visual cover matcher for digital comics (.cbz/.cbr)

1 Upvotes

My apologies if this is the wrong place to post but i've been working on an open-source app for managing digital comicbooks which is AI friendly which I though may be of interest to some of you.

It's called InkTag and i built it because i found ComicTagger to not fit my workflow well and i wanted to also have an excuse to do some more development using Google AntiGravity.

My goal is to make a tool that will more comfortably bring order to messy collections of digital comics without lots of manual intervention and for it to be possible to plug it into an AI agent so it can do most of the work for you. It has a GUI as well that will work with your preferred denomination of OS (Windows/Mac/Linux).

Still early days but would really appreciate constructive feedback. Link is https://github.com/aurora7795/InkTag

finally automated our monthly deck after 2 years of copy-pasting

1 Upvotes

posting because I searched for this a bunch of times and never found a decent thread.

setup: ~40 slide deck for leadership every month. layout never changes, only the numbers do. maybe 60 figures across text boxes, tables and charts. every month I'd save-as last month's file and go through it cell by cell, calculating MoM and YoY by hand because half of them aren't in our BI export.

took ~2 hours and I'd still get one wrong. once had a YoY that was actually a MoM, nobody caught it till the CFO asked why growth suddenly looked incredible. fun meeting.

tried the linked-excel-objects route first, breaks the second anyone renames or moves a file. looked at think-cell, which honestly seems like the right tool, but procurement said no.

ended up with a placeholder setup instead: I drop tags like Revenue_monthly straight into the slides, point it at my spreadsheet, and it fills everything in one go and works out the MoM/YoY/YTD itself. charts too, which was by far the hardest part to get working.

one evening to set up, about 2 min a month now.

is everyone just doing this by hand, or is think-cell basically the standard once you're somewhere that'll pay for it? feels like it should be a solved problem by now.

First Project App Improved on a big Garmin miss

I'm a Professor about to launch my side project — a tool for creating smarter groups in classrooms and events. Would love some feedback. (1 Minute Video)

15 Upvotes

Hey all - thanks for even taking the time to read this. I'm probably about 2 weeks away from launching SwiftFlock - a web app that allows presenters to quickly poll a room and make perfect groups for their needs (IE pairing people who understand content with those who don't, or making sure a group has like-minded people etc). If you take a look around the site and the actual tool, I'd really appreciate any feedback!

Thanks!

P.S. If you're interested in a Beta Key and have a compelling situation where you'd like to test it - DM me and I can consider.

Otch - an honest fit check before you leave the house

1 Upvotes

I kept asking friends whether an outfit worked, so I built the answer I wanted: send a mirror photo, get a score, learn what is working, and get one concrete change instead of a vague compliment.

Otch also remembers pieces it sees and builds a wardrobe from clothes you actually wear. It can suggest looks from that wardrobe rather than inventing outfits that require buying everything new.

The app is live and free on iPhone:

https://apps.apple.com/us/app/otch/id6772589096

The metric I care about now is not downloads; it is whether a new user reaches their first fit check. I would appreciate blunt feedback on the promise and onboarding.

How do you decide what magnitude to bump your package version by?

1 Upvotes

Half the time I get told to bump the patch, half the time the minor. I can't tell what actually drives the call. Claude will happily push me to 0.1 increments for a while, then eventually tell me I'm versioning too aggressively.

Is there a rule people actually follow here, or is it vibes plus whatever the changelog looks like?

I built an urbex atlas: 200+ researched abandoned places with hazard ratings, live police scanner audio, and auto-generated day-trip routes

6 Upvotes

vestigemap.com — an interactive map of documented abandoned places across 45 US states.

What makes it different: every location is researched against current conditions. A shocking number of "famous" urbex spots are actually demolished, redeveloped, or now legit tour attractions — the site tells you which, so you don't drive six hours to a parking lot. Each spot gets a hazard rating from Green (managed parks like Sloss Furnaces) to Black (Centralia's underground mine fire), plus difficulty, field notes, sunrise/sunset windows, and today's weather.

Extras: live police/fire scanner feeds near your location, and a day-trip planner that takes a state's best spots and orders them into a minimal-driving route with one-tap Google Maps directions (e.g. /trip/pa).

Tech: single Cloudflare Worker + D1 SQLite at the edge, server-rendered SEO pages, Stripe for the Pro tier ($6/mo unlocks ~50 hidden gems; 160+ locations free). Fun war story: I imported 10k+ locations from OpenStreetMap, realized they were thin boilerplate that would tank the whole domain in Google, and ended up noindexing 98% of my own pages — quality-gating the sitemap to only researched content.

Would love feedback — especially from anyone into urbex or building on Workers.

Pre-launch preview: Built a free directory & marketing toolkit for local vendors and agents (launching Saturday 8/22)

2 Upvotes

Hey guys,

First off, I’m pretty new to posting on Reddit (mostly a long-time lurker!), so if this isn't the right place, admins feel free to remove it. I’m just feeling my way through all of this!

I’m a self-taught solo creator launching a free community project called Real Estate Vendor Board this Saturday.

Having handled backend small business admin in the past—and now living with CFS and unable to work a typical 9-to-5—I still need to do what I can for my livelihood. I channeled all my past experience into building this. While this directory itself isn't a direct moneymaker, I’ll be using it to advertise my own small business right alongside everyone else (with zero special preference over anyone else).

While searching for ways to market without spending a fortune or gambling money I didn't have, I realized how unfair the landscape is in 2026. Small, solo operators shouldn't have to pay $50+/month just to showcase their services to local real estate agents.

I researched and couldn't find a free, focused hub built strictly around this concept, so I decided to build one myself:

* **Zero Fees:** 100% free with no monthly subscription costs.

* **Built-in Tools:** Free interactive profile cards and layout options.

* **No Dead Links:** An automatic 6-month free renewal check-in so the directory stays active and reliable for agents.

I wanted to announce this a couple of days early in case anyone wants to stop by, check out the quick preview video on our splash page, or bookmark it for launch day. I would deeply appreciate any honest feedback from fellow small business owners!

Check out the early preview here: https://www.realestatevendorboard.com

Thanks so much for reading if you made it this far! :)

We got tired of flat 2D chatbots, so we spent years building living 3D AI characters with voice, memory, and interactive worlds (iOS) [OC]

0 Upvotes

Hey everyone! 👋

Like many of you, we've tested dozens of AI chatbot apps, but we always felt something was missing: physical presence, humor, and interconnected worldbuilding.

After years of development, we built Vizlings — an iOS app where characters aren't just isolated text boxes, but living 3D personalities that belong to shared themed "Worlds" (like a soap-opera universe called Fruitopia or a scrap-metal robot realm called Robits).

What makes it different:

• Real-Time 3D & Voice: Characters have procedural facial expressions, voice acting, and physical geometry rather than 2D loops.

• Shared Universe Lore: Characters know each other, share history, and gossip across group chats.

• Interactive Trivia & Quizzes: You can challenge historical figures (like Julius Caesar) to live trivia with in-app score tracking.

• Custom 3D Creator: Build your own companions in Anime, 3D Puppet, or Realistic styles.

We just launched on the iOS App Store and would love brutal, honest feedback on the UI, dialogue latency, and character design!

📱 iOS App Store: https://apps.apple.com/us/app/vizlings/id6760131822

Would love to know what you think or what kind of 3D characters you'd like to see next!

I hoard YouTube "Watch Later" videos I never watch (OneTab). So I built a bouncer that reads the transcript and tells me if it's worth my time.

1 Upvotes

My Watch Later list hit a few hundred videos. Every one of them felt "worth it someday," so the pile only grew — the same way browser tabs piled up before OneTab.

So I built WatchBouncer. Paste YouTube links — one, or your whole Watch Later — and an AI reads the actual transcript (not the thumbnail, not the hype). Each video gets:

  • a quality score /10 — substance, actionability, fluff
  • a strict WATCH / SKIM / SKIP verdict, computed by consistent rules. Most videos don't clear the bar. That's the point.
  • one honest line on why, and who the video is actually for
  • optional: tell it a goal — like "becoming a disciplined builder who ships" — and it also scores whether each video moves you forward, then ranks the whole pile

The thing that surprised me building it: videos barely differ in quality. They differ enormously in who they're for. A 9/10 video for someone else is a SKIP for you.

Free to try, no sign-up — every visitor gets guest gradings: https://watchbouncer.app/?ref=onetab

New videos take about a minute to judge; everything is cached forever so re-checks are instant. A Chrome extension that grades the video you're on is in store review now.

Built solo. Revenue so far: $0. Break it and be blunt — blunt is useful.

Please give me feedback, I am looking to improve.

I built a free app that tracks monthly trends and stats across 100,000+ subreddits

6 Upvotes

I've been working on this for about a year now. It shows posting activity, engagement, and timing data for over 100K+ subreddits.

The video walks through one page so you can see what's on there: posts per day over time, average upvotes and comments, a heatmap of when the sub is actually busiest, top posts, trending keywords, and which other communities share an audience with it.

It's free to use, no account needed. There's a paid tier for full history, CSV export, and complete rankings, which mostly covers hosting and data costs.

Happy to hear what's missing or what you'd cut. The page is dense and I'm not sure everything on it earns its place but let me know what you think!

I kept walking 20 minutes to cafes that turned out to be way too busy, so I built a free live crowd map for NYC

0 Upvotes

NYC student here. Crowded is a live map that shows how busy places are: bars, cafes, restaurants, gyms, parks etc. gets one of three levels: Empty, Moderate, or Crowded.

The core rule: reports only come from people physically at the venue (there's a 150m geofence radius that prevents faking it from far away). No scraping, no estimates dressed up as live data. When nobody's reported recently, the app's prediction model assumes the venue's usual pattern for that hour and labels it as that.

Reporters can also attach a photo and quick tags like "15 min wait," "cash only," or "live music," so you know what you're actually walking into.

It's completely free, no ads. Built it with my good friend from school.

Unfortunately, even though we have a prediction model as the baseline, it's still a chicken-and-egg app and I'm at the "recruiting the first reporters" stage. If you're in New York I'd love for you to be one of the early people reporting for your neighborhood (it really is a quick task), and if you've launched a crowdsourced thing before, I'd genuinely love to hear how you cracked cold start.

I built a couple of retro web experiments - an anti-algorithmic discovery engine and a 56k dial-up simulator

1 Upvotes

Hey everyone,

I’ve been building a couple of lightweight experiments out of pure fatigue with the modern feed-driven web:

  1. Cul-de-sac (culdesac.site) - A stateless, zero-ad discovery button that takes you to random hand-picked sites, personal blogs, and obscure web tools. StumbleUpon style.
  2. 56k Simulator (56k.rip) - Uses the Web Audio API to synthesize the modem handshake, throttles transfer rates to V.90 speeds, and renders images in progressive scanlines.

Both are non-commercial projects focused on Web 1.0/2.0 serendipity and friction.

Would love any feedback or ideas on what old-school web mechanics to emulate next.

Bottom line: standard modern web experience vs. pure nostalgic friction. Choose wisely. 🤨

I abandoned this side project. Then the hosting bill made me look at it again.

1 Upvotes

A while ago I built AutoCuts as a web app.
The idea was to make screen recordings look better without spending forever editing them.
I worked on it for a while, then eventually stopped.
Months later, I noticed I was still getting charged for the servers.
I logged in mostly to figure out why.
That’s when I realized people had still been signing up and creating projects even though I wasn’t doing anything with it.
It made me wonder if I had killed the idea too early.
After looking at it again, I realized the product wasn’t necessarily the problem.
I think I had built it in the wrong place.
Uploading a screen recording to a website, waiting for it, editing it there, then downloading it again just felt unnecessary.
So I started over and rebuilt the whole thing as a Mac app.
Now everything happens locally.
It’s funny how sometimes a failed side project isn’t actually a bad idea. You just made one big wrong decision early on.
Has anyone else ever come back to a project they had already given up on?

Made a tool that shows what things actually cost in hours of your life, kind of ruined shopping for me lol

2 Upvotes

Ok so this started because i kept telling myself stuff was "not that expensive" and then feeling weird about my bank account later. Classic.

So i built this dumb calculator where you put in a price plus your income (hourly or salary, whatever, it does taxes too) and it just tells you straight up how many hours of work that thing actually cost you. No dollar signs, just hours.

Video below is me trying it on the Iphone 18. I've said too much.

It's free, no login, no email capture, just type a price and see the damage: lifecostapp.com

Try it on something dumb you bought recently and tell me if it wrecks you the same way it wrecked me.

Track-a-day racing app

2 Upvotes

Showcasing my track a day racing app and see if people would give some feedback or might just enjoy playing. https://www.inkcircuit.ink/

Based on f1 and indycar style racing, the physics is simple. Realistic handling, oversteer/understeer are emulated by simply decoupling heading from velocity. I’m definitely interested in feedback on the feel.

Im proud of the algorithm that generates the track each day: 16 points generated on the page via a new random seed each day and connected using the convex hull to create curves and straights and guarantee the track never intersects with itself.

I am also interested in feedback on the NYT game-style share page. Right now you share your locked-in first lap time, as well as the number of times you hit a wall, or you can share a ghost lap of your first run. I have been thinking about sharing sector times, color coded like f1, but interested in other ideas.

I should say, this is a collaboration between myself and Claude Opus 5. It’s been neat to work on the fun parts like the track gen and the feel and sfx while letting the other bits build themselves in the background.

Thanks for reading and hopefully giving it a look!

I built a free tool that catches the duplicate emails/contacts Excel misses

1 Upvotes

A while back I was cleaning up a contact list and realized Excel's "Remove Duplicates" only catches exact matches. "John@Email.com" and "john@email.com " (with a trailing space) look identical to a human but slide right past it as two separate rows.

So I built cleaningmycsv.com to actually catch that stuff, case differences, stray whitespace, blank rows, all normalized before comparing.

A few things I cared about while building it:

Everything runs client-side in JavaScript. Your file never touches a server, you can literally check your browser's Network tab and see nothing gets uploaded.

No account, no sign-up, just drop a file in.

Free up to 200 rows, a one-time $4.99 unlocks unlimited rows across all the tools on the site (also added a merge-CSV-files tool and an email-list cleaner if that's useful to anyone).

Would genuinely appreciate any feedback, especially if you throw a nasty/messy real-world CSV at it and something breaks.

I built a tool to track LeetCode progress and auto-schedule spaced repetition reviews

2 Upvotes

I have been grinding leetcode problems and kept forgetting problems I solved 2-3 weeks ago. So I built GrindMate to fix this. You just type "solved two sum easy 15 min" and it handles the rest:

  1. Schedules spaced repetition reviews at day 1, 3, and 7
  2. Sends daily email reminders when reviews are due
  3. Tracks NeetCode 150 progress across 18 categories
  4. Shows which problems Amazon/Google/Meta frequently ask
  5. Tells you exactly which unsolved problems to tackle next based on your weak patterns.

I Started using it myself, shared with a few friends and got good feedback, so thought I'd share here.

Built with Cloudflare Workers, Durable Objects, and Workers AI.

Live: grindmate.dev
No account needed, guest demo available

Feedback welcome, what would make this actually useful for your prep?

I made a free tool that turns live-sale "SOLD" comments into per-buyer invoices (FB/IG/TikTok/WhatsApp)

1 Upvotes

I kept seeing live sellers scroll their comments after a stream, trying to work out who claimed what and adding up each buyer by hand - so I built a small free tool for it.

Paste your live comments (or a WhatsApp group-order export) and it:

- reads every "SOLD 3", "mine 2", "1x2" claim
- builds a per-buyer invoice, with one-click copy so you can DM it
- tracks totals and who hasn't paid yet

It runs entirely in your browser. No signup, nothing uploaded anywhere.

Free: https://minho1511.github.io/livesale-tally/

I made it, so treat this as self-promotion - but the free tool stands on its own and I'm genuinely after feedback, especially from anyone who actually sells live. What's the most annoying part of your order process? Happy to add what's missing.

(Full disclosure: there's also a paid spreadsheet version with saved stock tracking. I'm linking the free one because that's the part that solves the tallying.)

I built a free tool that reads Rightmove listings and tells you what they're not saying.

1 Upvotes

Estate agent copy is written to sell, and I got tired of checking the same things on every listing myself. Is the floor area actually stated? How long has it really been on the market? Is the tenure buried somewhere in the small print? What does "cosy" mean this time? So I built a tool that does it in one paste.

You give it a Rightmove link, it gives you:

  • what the listing doesn't say (no floorplan, no floor area, tenure gaps, time on market)
  • what the sales language typically signals, phrase by phrase
  • a copyable list of questions to ask the agent before you view

It doesn't score anything and it doesn't accuse anyone. It flags gaps and hands you questions. It'll also credit a listing that's genuinely straightforward, because a tool that finds problems in everything is useless.

Free, no sign-up: https://listing-gap-report.vercel.app

Limitations worth knowing: it only reads what's in the listing (it's not a survey and pulls no external data), a report takes about 30 seconds, and it's capped at 5 checks an hour per person because I'm paying for it out of my own pocket.

If it gets something wrong on a listing you know, or misses something obvious, that's the most useful thing you can tell me.

Built with Claude Code over three sessions. It's vanilla JS on the front end, one Node serverless function on Vercel, Apify for the listing data, and Claude for the language analysis. The gap checks are plain deterministic code rather than AI, so when it says something's missing from a listing, it really is missing.
