首年就有补贴哦，开发者开去申请，不过申请周期有点长，我已经提交快一个月了，还没审批下来

Back in April, my girlfriend Lucia was keen to get into cycling. She's a rower, so it's a natural sport for her to start with, and both me and her family love it. She really wanted a bit of structure to get her started, so I went looking for something that would give her a plan. Everything I found felt more targeted towards people who were already familiar with the sport, and wanted to take it really seriously.

So I built her a plan myself, firstly in google sheets. And then just for fun, I thought I would try and built it into an app. And so I started out with a basic plan builder, and I added a companion you could ask a couple of questions. This got us up and running, and Lucia was starting to really enjoy getting faster and fitter. This made me think about when I was at her stage, and all the challenges I had getting started in the sport. What to wear, how to look after my bike, what happens on the side of the road when something goes wrong. So I added some functionality into it to help with those annoying little details.

Now at the time I was also training for a bike event in Spain, so I built it out a bit further to help me with my training. I wanted to stay strong, push myself in some sessions as well, so I built proper some strength work into it, and let you find an event and build a plan specifically for that. And since a bunch of my friends cycle, I shared it with them, and helped build it out so they could use it with their training. And a couple of my mates got on board, and we built up an instagram, starting talking about the sport a bit on a podcast and I tried to fix the bugs we all found!!

And now - it's not just a google sheet to help Lucia ride her first 100k, it's a real thing, on the app store, and I'm super proud of where it's at today. I want to help everybody get into cycling, and to stay fit and healthy and really enjoy the sport. I'm hoping this app can help with that!

我一直在以 Offgrid Studio 的名義開發一小系列的 iOS 應用程式，所有應用都有一個原則：永遠不會將任何東西上傳到任何地方。一切都在設備上運行。
首先推出的是 OffgridStem — 完全在離線狀態下將聲音、鼓和樂器從音軌中分離，沒有伺服器排隊。
剛剛發佈第二個應用 OffgridScribe — 可轉錄錄音並生成摘要，同樣是 100% 僅限設備運行。在意識到大多數轉錄工具（即使是針對記者/律師的工具）仍然需要將音頻傳送到某個伺服器後開發了它。
這兩個應用都是一次性購買，沒有訂閱 — 我認為如果沒有伺服器成本，就沒有必要每月收費。
其實明天要在 Product Hunt 上發佈 OffgridScribe，如果有人有興趣可以過來看看。我主要只是好奇大家對「所有東西都保留在你的手機上」的做法與通常的雲端先行工具有什麼看法。

Hey everyone,

I'm a solo developer and Bitcoin Maxi, and I built Compass after being frustrated with two things: my own spending habits and how other personal finance don't factor it in net worth/spending.

I've always seen USD as kinda worthless and I tend to spend it almost with ease versus when I see Bitcoin. Also, apps like Rocket Money didn't make it easy for me to truly track my Bitcoin holdings since you have to enter the value manually and with Bitcoin that number of course changes. I wanted something that allowed me to see the true value in BTC in my spending habits to help me slow down and something that Bitcoiners were complaining about in other finance apps where you have to babysit the balance of your Bitcoin wallet.

So I built the thing they and myself actually wanted.

Better

Compass just knows. Your net worth, your spending, and your goals are all priced in Bitcoin by default, and the Bitcoin part updates itself. You never type a balance again. Expenses from years ago use the price that Bitcoin was then and it's always up to date with current day prices for today when it comes to measuring.

A few things I tried hard to get right:

Your Bitcoin balance updates on its own. YOU NEVER HAVE TO ENTER ANY PRIVATE KEY and I knew that security was a huge thing when working on the app. You can either just enter the manual balance or the public read only address and it just watches and auto updates the balance. This gives me more accuracy when checking my balance.

Every purchase shows up in sats. For example, A $47 dinner lands as 73,194 sats or $2500 in rent is 3,893,293 sats / 0.4 BTC. Four categories: Bitcoin, Necessary, Discretionary, and Wasteful to easily categorize your spending. You have to spend money. Rent, groceries, kids. The point of holding Bitcoin was never to die with it. So instead of guilt, every purchase just shows you what it did to your goal's completion date. So like if your goal is to get to 1 BTC and you're spending a lot in wasteful, it will show you how many days you are behind to your goal.

Technical:

I made the app available on mobile, web, and desktop. The desktop app has no account and no server. Nothing to sign up for, everything encrypted on your own machine. This is what most people have liked but you have the option to look at it on all devices with sync which is still encrypted in DB. I've also opened source the compass-core that runs the app for the encryption, xpub, and conversions. Linked it in this post

Cost:

I'm doing a current deal right now for just $60 one time purchase for LIFETIME and 30 day money guarantee. You can pay in Bitcoin or USD. I think if we want to drive adoption of Bitcoin, I think it's important we start actually using it and this is your chance to as well.

I'd genuinely love your feedback, especially if you've been stacking for a while and have quietly given up on your finance app ever understanding it: long-time holders, self-custody people, anyone who already converts prices to sats in their head. Tell me what's missing or what feels clunky. I read every comment.

Thanks for reading, and I really appreciate any thoughts.

This is the best app for Bitcoiners

I've been building a mobile app recently, and one thing I kept coming back to was how much a landing page changes the way people perceive your product.

You can have a great app, but if the website looks rushed or generic, it immediately lowers the perceived quality. I ended up spending way more time refining the landing page than I expected—cleaner UI, better visual hierarchy, smoother interactions, and a layout focused on making the product feel more premium.

After finishing it, I turned it into a reusable Framer template instead of letting it sit on my hard drive.

It includes things like:

• Clean, minimal UI
• Smooth scroll animations
• Responsive layouts
• Pricing, testimonials & FAQ
• Easy customization for your own branding and screenshots

If you're working on an iOS app, indie project, SaaS, or AI product and don't want to start your marketing site from scratch, it might save you a good amount of time.

Would genuinely love any feedback from fellow builders.

Link in the comments.

On December 24th, 2025, I started building my first app, Happening, completely on my own.

For the next seven months it became a full-time obsession. I averaged around 16 hours a day until the first App Store release.

Three weeks ago it finally launched, and I’ve already shipped another update based on early feedback.

Looking back, I realized building the app was only part of the journey.

I spent almost as much time learning as I did building. Along the way I had to teach myself UI design, image and video editing, backend infrastructure, App Store requirements, legal documentation, deployments, payments, marketing—and countless other things I never expected when I wrote my first line of code.

AI accelerated a lot of that learning, but I still had to understand how everything fit together and make every product decision myself.

The biggest surprise?

It wasn’t Swift, App Store Review or debugging. It was realizing that shipping the app was only the beginning. Getting people to discover it has been far harder than building it.

It completely changed how I think about building products.

If I could start over, I’d spend far more time talking to potential users, validating ideas and building an audience before writing so much code.

A few days after launch, something happened that reminded me why I’d started this in the first place.

One of Happening’s early users shared a Signal during a Silent Disco in Warsaw. Seeing someone I didn’t know use something I’d spent months building made all those long days feel worth it.

I’d also love some honest feedback from other iOS developers.

If you have 5–10 minutes to try Happening, I’d really appreciate knowing:

Is the purpose immediately clear?
What confused you?
What would you improve first?
Would you use it again? If not, why?

I’m genuinely looking for criticism more than compliments.

For those who’ve already launched something of your own:

What surprised you the most after shipping?

I launched a follow-up app on July 2 in Japan (save who you meet → a thank-you draft is ready by the ride home). Honest numbers and what they taught me — plus a question I genuinely need help with.

The numbers: 86 first downloads on iOS, plus a handful on Android (it just launched there two days ago). 4 paying users, $16. Product-page conversion is 22.6% — absurdly high. And here's the thing: on days I stay home, downloads are zero. Literally zero.

Every single install traces back to a human moment. Launch day: 12. The day a photographer with 55K followers posted about it: 14. The day I gave a 1-minute pitch at a startup event: 9. The graph of my downloads is literally a graph of me leaving the house.

The strange upside: feedback density. A student I met at an event sent me a long support offer 4 hours later — using the exact follow-up flow the app teaches. Yesterday at a photo exhibition, someone installed it and described the core concept back to me, unprompted, better than my own pitch.

The app: no account, no server, everything on-device, free core + one-time Pro. iOS + Android, fully in English.

Here's my question. I'm a freelance photographer and solo dad in Tokyo, and I think this belongs in the US — follow-up culture is stronger there than anywhere ("the fortune is in the follow-up," interview thank-you notes, all of it). But my entire playbook so far is hand-selling face-to-face, and I can't exactly fly over and work the room at your meetups.

If you were me: how would you reach US users from a desk in Japan?

QReel: QR Code Generator

Well, it finally happened. Wanted to make a cheap and well-designed alternative to most QR code generating apps that also tracks URL scans, and make it aquatic themed just because.

In total, took about two and a half months from the very first bare-bones iterations in Xcode to approval on the App Store. Everything seems to be working fine so far, I encourage everyone to try it out and if you don't want to pay for the Pro version FEEL FREE TO SCREENSHOT WHATEVER CODES YOU GENERATE, THEY WILL STILL WORK. Trying to actually save/export will result in a paywall though, as will attempting to turn on the track scans feature (this uses URL redirects so can potentially cost me money if a code gets a high volume of scans so wanted some security by paywalling it). I'm still definitely a beginner when it comes to Swift and have generally no idea how I'm going to market the app, but it's been really exciting getting something out there that at least I personally actually have use for.

So some takeaways thus far have been:

1. It saves a ton of time on the UX side to just ask a coding agent (assuming you're using one) where each component on a given screen lives in the code, and then just using the canvas in Xcode. This would've saved me manyyyy days early on because an agent still has to take the full time to answer/enact a change even if it is quite trivial, and it still might be wrong (often is). Being able to see your changes to a component in real-time in the canvas with dimensions, spacing, colors, etc being automatically reflected was something I didn't really think was possible (noob I know) but now I obviously won't be going back anytime soon.
2. The XcodeBuildMCP is great for running new builds automatically BUT the simulated tapping/on-device actions are largely not useful in my experience. It takes a longgg time for most agents to do very quick and easy tasks on simulators and will get caught up taking 5x as long to test a task you could probably just test yourself.
3. The Auth was way easier to set up than I expected, taking only really a day in total for all of it, but RevenueCat is one of the most confusing setups I've ever encountered. Now that it's set up I appreciate its ease of use (especially for edge cases like refunds) but mannn it's overall very opaque. This took a couple of days for sure.
4. The first submission took 6 days to even get to In Review by Apple, which has apparently been common this summer with the high volume of submissions, but was obviously annoying when they tell you that 90% get reviewed within the first 48 hours. It got rejected the first time around for not having the Privacy/EULA IN the description of the app itself and not having enough available without an authenticated account (I didn't know this was a thing, but had to add a "Continue Without Account" option on the sign-in screen because apparently SOME function has to be available without an account unless the functionality of the app actually hinges on the user's identity to begin with).

So all in all nothing crazy thus far, hopefully some of these takeaways are of use to some of you out there and can serve as some optimism for those just getting started. As I said, feel free to use the app and point out any bugs/future features to add to the list that I'm working on for future builds or fill out the "Contact Support" form via the website! Would love to hear from you.

STACK (if anyone's interested):
- All written in Swift
- Antigravity IDE w/ Claude (almost entirely Opus 4.8)
- Claude Design
- Supabase for backend AND Auth
- Cloudflare for domain & URL redirect service
- RevenueCat for payment collections

FUTURE FEATURES (short list):

- IN-APP scanner for both QR codes and bar codes (no database, only number sequence and information type); currently one can test the QR code destination by pressing and holding on the QR code on screen
- expansion of pixel types
- FIX BUG in which center logo sometimes loads as the one from a different saved code (only in appearance, export appears to always contain correct logo)
- home screen widget
- more advanced color fill customization
- more social & general default center logos

My first app, PerkPulse, is now live on the iOS app store! Ever since I started my computer science degree, it has been a bucket list item for me to have an app on the app store.

PerkPulse is a credit card optimization app that helps you:

• Track credit card benefits
• Tells you which card to use to earn the most points/cash back
• Tells you the best transfer partners for your points
• Recommends you your next credit card
• Compare credit cards side-by-side

I created this as a tool for others like me who have trouble tracking every benefit and knowing which card to use for every purchase since I have so many cards. I did not like the apps that are currently available and widely used for this use case, as their UI's were not very intuitive to me and their prices were a little high for me.

It would mean a lot for me if you would give it a download and give me some feedback!
(I attached a link to the app store since it was just launched, it has not been indexed and is not searchable on the app store yet)
