What a crazy week. In addition to new updates for my license plate app, I built three new Mac apps. Each of them serves a different purpose and was created to simplify my workflow. I am most proud of a (not-so-small) GeoJSON viewer app. #BuildInPublic

Excited to announce that Aeronaut is now live in the Mac App Store! 🎉 After two years of tinkering, polishing, and obsessing over the little things, it’s finally here! If you’re looking for a Bluesky app designed and built for macOS, take a look… apps.apple.com/us/app/aeronau…

Oh my! My app has quietly surpassed 500 ratings globally, and it's still rocking at 4.9! 🤩🥳 I couldn't be happier! #IndieDev

I'm working on the next version of my app and finally decided to reduce its size (was 300 MB). After days and nights of compressing and optimising images, plus a small breakdown yesterday when it reached 1 GB 🫠, I'm happy with the result: only 80 MB! 🥳🥳🥳 #BuildInPublic

Friendly reminder to export your app assets as HEIC instead of PNGs! For Art of Flora, this lead to an almost a 85% reduction of size 😱 #buildinpublic

🚨THE WAIT IS OVER🚨 I’m very happy to announce that my little license plate app is now also available on Android! 🤖🎉 #buildinpublic #indiedev

There's reason to celebrate! One year ago today, Kennzeichen Wiki was released in the App Store! 🎈🎂 A lot has happened in the meantime, and even an Android app is in the starting blocks 😎 At this point, I'd just like to say a big thank you to all of you! Here's to many more years! 🫶 #BuildInPublic

I'm not sure if a macOS app can be more niche than this: I wanted to access the macOS share sheet in @vivaldi.com faster, or by clicking on a button, rather than using File > Share. So, I built an app for it. You can join the TestFlight, if that is your thing. www.philipptemmel.com/writing...

Great, looks like I found my first copycat… not sure if I should be flattered or pissed 😑 #indiedev

Rate my setup for tonight's coding session: A cold beer, lofi sounds, cozy light… could be worse 🥰 #BuildInPublic

Getting closer and closer to full feature parity! 😎 Happy weekend y’all! #buildinpublic

Hot take: The more I work with Jetpack Compose and Kotlin AND SwiftUI on iOS, the less I get why companies still prefer cross-platform solutions. It's been less than a month and my app is 95 % ported to Android. Sure, it takes time but the outcome is so much better. #buildinpublic

Looks like I'm also becoming an Android dev soon… 😅

In iPadOS 26, the new menu bar automatically adds an action that links to your app’s system settings. However, pressing [⌘,] should usually open your in-app settings. Using CommandGroup (replacing: .appSettings) takes care of that. #SwiftUI

Today, for the first time in seven years, I ran a 20k race, and boy, does it feel good!

"License Plate Wiki & Collect" by @yanlu.chat License Plate Wiki helps you identify and track European license plates with a searchable database and interactive map. indieappcatalog.com/app/905

All good things come in threes! 3️⃣🎉 Version 3 of License Plate Wiki is now available and comes with Liquid Glass, Statistics (finally) and 12 (!) new countries! #BuildInPublic #iOS26

Good news! Version 3.0 was approved overnight, so it's ready for the iOS 26 launch on Monday! 🚀🎉 #iOS26

Here we go!! 🤞 #BuildInPublic

Quick question: how can I create Shortcut groups like these? What are those called? #SwiftUI

I'm this close to releasing the next big update with new features, content and Liquid Glass just in time for the release of iOS 26. So damn close! 🤏

Life of an #IndieDev in a nutshell…

Nice Friday surprise: My app got featured on appgefahren again! 🤩 www.appgefahren.de/kennzeichen-...

Damn, Liechtenstein! 🇱🇮 The Specular highlight looks good on you! 🪩✨ #iOS26

A little while ago, I had the pleasure of creating the new app icon for Ocean 🌊 I’m thrilled to finally see it out in the wild! Congratulations to the team! 🎉

My little app just passed 200 reviews worldwide! I’m incredibly grateful to everyone who’s taken the time to leave feedback and support this project. It truly means the world to me. Thanks for being part of this journey! Here’s to the next 200! 🚀 #IndieDev #BuildInPublic

License Plate Wiki v2.1 is here! 🚀 Now with license plates from Belgium, Italy, Croatia, Norway, and Slovenia. Update now and keep expanding your collection! 🙌 #BuildInPublic #indiedev

Fingers crossed! 🤞 Really excited to ship this one! #BuildInPublic

After playing around with all the effects for a while, the Icon Composer is really fun! 🥃 I was planning on embossing letters anyway, so timing is perfect! #iOS26

Okay, so the most important question we've all been asking: Yes, the radius of the Squircle™ has changed! 😱 The default app icon size is now 64×64 (nice!), with a corresponding radius of 16.5. Here's the difference: #iOS26

Icon Composer developer.apple.com/icon-composer/ #WWDC25 #Apple

New Toggle style? Also, for the first time ever (?) the default cell height is not 44 pt anymore? #iOS26

Looks like my apps is ready for #iOS26 from day one… 🤪 At least the widgets and even the app icon (probably due to the tinted version)?!

Even the pagination dots reflect 😍

New TestFlight icon. Who dis?

Solid keynote! My favorite part was the Macification of iPadOS ✨🤩 The timing porting my app to iPad couldn’t have been better! #WWDC25 #iPadOS

See you on the other side 👋2️⃣6️⃣

Slopes and Dark Noise get mentions in the keynote!!?? Dang - congrats, @curtisherbert.com & @charliemchapman.com ! #wwdc

Today is finally the day! Even though I couldn’t make it to the event in person, I’m really excited to see what will be unveiled today. #WWDC25

In other news, “License Plate Wiki” received its first ever video review (in German) ✨ Thank you Marion and Michael! 🥰 www.youtube.com/watch?app=de...

Due to displaying more countries, I had to find a better solution than using a Menu. v2 was an adaptation of the .pickerStyle(.inline) but I didn’t like the whitespace caused by the checkmark. So I opted for a custom solution (v3), which even displays the progress of seen plates. #BuildInPublic

Hallo, Zdravo, Ciao, Bok and Hei! 👋🇧🇪🇸🇮🇮🇹🇭🇷🇳🇴 Exciting news: Version 2.1 will include far more countries than originally planned—bringing the total number of plates to over 2,000! 🤩 Just putting on the final touches, so stay tuned! 🔜 #BuildInPublic

Dumb question: Is there no way to open a SwiftUI Menu with a .keyboardShortcut? #SwiftUI

I've been working on a new version of the @indieappcatalog.com, and it’s almost done. You can see a preview here: indie-app-catalog.pushtomain.de. I’d love to hear your thoughts, suggestions for improvements, or any feature ideas you might have.

3… 2… 1… Liftoff! 🚀 I'm very happy to announce version 2.0 of "License Plate Wiki" is now available on the App Store! 🎉 With an iPad app and many new features! #BuildInPublic

Weekend treat! 🍫 Couverture is free this weekend — no strings attached, just sweet software goodness. Enjoy and share the love! → apps.apple.com/app/id155241...

Good news! The submission was approved and with that, everything is set! Version 2.0 will launch next Wednesday, April 30! 📆 🎉

Have you already closed your rings? #CloseYourRings

IT'S HAPPENING! 🤞🎉 #BuildInPublic #IndieDev

I dug a little deeper into SwiftData and added one last quality of life improvement for version 2.0: widgets now show favorites and seen status and can now be filtered accordingly ✨ #BuildInPublic #SwiftData
