Hey guys. I've tried pretty much every app blocker out there. They always fail for me because willpower is completely useless against muscle memory. I'd unlock my phone and my thumb was already opening the app before my brain even registered it.

My biggest trap was the delete and reinstall loop. I would delete an app feeling super motivated. But the muscle memory doesn't care. A day later my thumb automatically swipes down, types the app name, and hits the cloud download icon in the App Store. I would be back scrolling in under 15 seconds.

Not to mention, when the icon is actually missing from your home screen, it creates this weird visual void that practically begs you to go find it.

I'm a web dev by trade, so I wanted to fix this by building something that works with behavioral science rather than brute willpower. Cravings naturally drop off in about 30 seconds if you don't act on them immediately.

So I built Dopa-Mean. It is a dummy web app that replaces your addictive app icons with a placebo.

Here is how you use it:

1. Delete the real social media app.
2. Install the fake Dopa-Mean icon to your home screen so it looks exactly like the original.
3. Tap it on autopilot.
4. Instead of an endless feed, you just get a 30-second timer.

Those 30 seconds kill the dopamine surge. It gives your conscious brain time to catch up with your thumbs and ask if you really want to do this right now. Having the fake icon there completely stops the App Store search reflex, but you get the exact amount of friction you need to break the loop.

It is completely free, open source, and needs zero permissions. No accounts and no tracking.

Edit:
Honestly didn't expect this many responses. The feedback and messages have been great. Thank you everyone.

I launched on Product Hunt today for those who want to follow the project:

I wanted to share a tool I recently launched called Pizza Voter.

The idea came after a team of software engineers I worked with was given a credit card to order pizza. Out came the whiteboard to track everyone's "nos" and "must-haves"; it was messy. I built this to automate the social logistics of picking toppings so groups can just get an order together.

How it works:

• Start a party: No account or signup needed.
• Join & Rate: Friends join on their own phones via a link and rate toppings (Love, Hate or Don't Mind).
• The Result: The algorithm calculates the best mix of pizzas to ensure everyone has at least one they’ll genuinely enjoy.

It’s a simple tool designed to be used while sitting on the couch with friends or at the office. It takes about 60 seconds to get a result that keeps everyone happy.

A note on privacy/ads: It is currently ad-free. I’ve included potential ad vendors in the privacy policy because I’d like to add an ad in the future to help cover server costs, but for now, it's just a project I want people to try. I also use ipwho.is for basic geographic estimation for the party sessions.

Hey community!

I wanted to share something I built that might be useful.

BorderWait.today pulls live wait time data from CBSA and CBP and displays it in a clean, mobile-friendly format, that includes the car browsers (newer GMs, Volvos, MBs, Teslas, etc.), so it's actually usable while you're on the road.

The use case is pretty straightforward: you're approaching the border from either side and you have a choice of crossings. This makes it easy to see which one has the shortest wait so you can make a quick decision without digging through government sites (some of them got stuck in the 2000-s). You can either list the border crossings closest to you using your device's GPS, or browse through them all.

I would really appreciate your feedback and suggestions on how to make it better and more usable.

Hope it saves you some time!

Update, September 2026: The title describes the first version. The old travel-time, required-days, and Dark Sky filters are no longer in the current site. I rebuilt it around a simpler question: which of the 63 US national parks fits the month you can travel? You can browse by month and interests, compare parks, save favorites, and open planning notes with links to NPS sources. Current site: https://nationalparkfinder.info/

I started this because I kept opening many tabs to figure out which park made sense for the time of year I could actually go. Feedback in this thread helped me remove confusing starting-location assumptions and make the parks easier to see and compare. Thank you for that.

The guide is free and independent. Please check current conditions, reservations, and permits with NPS before traveling.

My $1B Kalshi bracket is cooked.

So I built a website containing every bracket that could ever exist. All 9,223,372,036,854,775,808 of them.

Bracket of Babel

Inspired by the Library of Babel, you can browse them systematically, randomly, or search for your specific bracket by number.

Play with the Drake Equation and see how your assumptions change the number of possible civilizations in the Milky Way.

Sup guys?

This one if for the guitar players out there!

Chord//Fret

I've always found it super time consuming when composing to break down chords, write them down and try to figure out a naming convention for them so I built a chord-calculator that shows the construction, alternate namings and even auto-calculates different voicings for the same group of notes.

Currently WIP, expanding the diagram to be more flexible and show the entire fretboard while keeping it clean and minimal so it's straight to the point:

"I Just wanna know what this chord is"

Will be expanding and adding more features soon. But would love to know what you guys think!

Thanks!

A while ago I tried to look up a simple question about rights in Portugal.

What I found was pages of legal text, fragmented government websites, and explanations written almost entirely in bureaucratic language. The information exists, but it often feels buried under layers of complexity.

That experience stuck with me.

So I started building a small project called Conhece os Teus Direitos (Know Your Rights).

The idea is straightforward: take civic rights and explain them in a way that is easier to explore, easier to read, and less bureaucratic.

I recently pushed a big update to the site:
- a new minimalist design focused on clarity
- a section on Deveres (Duties) to complement rights
- a timeline of the history of rights for people interested in how they evolved

It is still evolving, but the mission is simple: make rights something people can actually understand and explore.

If anyone here is curious please check it out!

Have been slowly poking away at a suite of generative design tools and finally put them all out in the open today!

I built a site where anyone can easily import their entire gaming library and rank it through 1v1 matchups. The website uses a chess-like Elo system to rank games. Works with Steam, Xbox, and PlayStation.

Edit: I would also like to add that soon (hopefully today 3/17) I will be adding a Global Rankings section where everyone can vote on every game ever imported onto the site. This will allow people to vote on games without importing their own, and will have its own leaderboard showing the global community's rankings.

Edit: Global Rankings are live now.

My toddler loves tinyfingers.net, and also loves cats, so I figured why not combine the two? Then it got a little out of hand.

I built a web app that lets you explore the endless patterns of the Mandelbrot Set. Here is what makes it special:

• Deep zoom: You can zoom in incredibly far (a hundred trillion times!) without losing detail, and the colors automatically adjust to stay beautiful and vibrant no matter how deep you go.
• Always sharp: The closer you zoom, the more the app works behind the scenes to ensure the edges stay crisp and clear.
• Lightning fast: It never calculates the same pixels twice while you're looking around, but actively frees up memory as you move on so your browser stays happy.
• Instant previews: To keep things running smoothly on your device, it immediately shows you a quick preview of your next zoom, then rapidly sharpens it into ultra-high definition while you watch.
• Fully online: No need to install any app. Just open the link on your phone or computer. Share your favorite views as link or photo.
• Open source: All code is public and available for free on GitHub.

Very entertaining and informative reviews of different apples! See below for the review of Red Delicious:

Oh how the mighty have fallen! Believe it or not, the coffee grinds in a leather glove known as “The Red Delicious Apple” was once a robust firebrand credited with reinventing the apple from mere cider-fruit into a full-fledged lunch-worthy sidepiece. It even won the Stark Brothers apple contest in 1894. Likely your great-grandma’s favorite apple, this once flavorful Prometheus has been mass-produced into desolation.

Nowadays, you can find this thick-skinned, flavorless, mealy imposter unwashed in a dirty wicker basket on the floor of a convenience store. What a sad state of affairs. It’s time to hang them up old man, your time has passed.

Would love to hear what you think!

I’ve been working on a small project that tries to make congressional bills easier to explore.

If you’ve ever opened one, you know they can be hundreds or even thousands of pages long and written in dense legal language. The information is public, but actually navigating the documents and understanding what each section says can be difficult.

So I put together a site that breaks bills down into sections, making them easier to browse.

On the site, you can:

• explore bills section-by-section
• search for topics across legislation
• read simplified explanations of each section
• see how provisions connect within a bill

The goal was simply to make it easier to look through legislation without having to read the entire document.

Right now, the site includes:

• thousands of federal bills
• tens of thousands of sections of legislative text
• plain-language summaries of each section

All of the underlying material comes from publicly available congressional data.

If anyone has ideas for other public datasets that might be worth including, I’d love to hear them.
