It should be easier to rank it in the keywords, as per @TryAstroApp is much more difficult to rank in "Plant Identifier" than in "Bird Identifier". Let's see how it goes and if the App Store initial boost still exists.

Need an ASO course ASAP!

After Greenie's launch I've been looking to make another AI identifier to use everything I learnt.

So here is BirdScout!
A bird identifier where you can see all bird information, take notes, mark spot location...

Would really appreciate if you can leave a rating. Link below!

New update of Greenie just launched!

It includes smart watering schedule for your plants, watering reminders and notifications, plant nicknames, list view and filtering for the garden and much more.

Wow, so many new followers from yesterday's post! Welcome, everyone 🤓

I'm now integrating the new watering tracking functionality into Greenie. Which approach do you think is better, A or B? I believe B is clearer and offers a better UI.

This is the next chapter of Metrociego Madrid. Originally, our app helped visually impaired users navigate stations, guiding them from platform to exit and between platforms during transfers. With 1000+ monthly users, we knew it was time to plan full journeys. Let's dive in! 🧵

I’ve just launched a new app! It’s called Quizquake. It's a super lightweight game where you go head-to-head with a friend to see who answers faster. The first to win 3 rounds wins the game!

Just got myself @useTRMNL—a fully customizable e-ink dashboard for tracking anything you want. Can’t wait to build plugins for it and make it my ultimate dev + life companion!

Big thanks to @itsdanstaub for the help!

In the next Leisurist update I also fixed two bugs that were driving me insane:
- A button animation bug that refreshed the view unnecessarily
- A delay where the next episode to watch in a series took forever to appear.

Feels like a victory—these fixes were long overdue!

Someone just got a refund for my app… tough luck, they’re gonna miss out on all the cool stuff that’s coming!

Been experimenting with MeshGradient for the background of the recommendation reasons in Leisurist. So far, it looks pretty neat—might stick with it!
December 15, 2024 at 5:53 PM
Just improved Leisurist’s recommendations! Now they come with 3 reasons why each suggestion might be perfect for you. Almost ready for release—can’t wait for you to try it!

Trying to make adding books to Leisurist as easy as grabbing them off the shelf—just scan the barcode and boom, it’s in! Planning to dive into this during the Christmas holidays… right after the AI update is out!
December 12, 2024 at 4:30 PM
How many free recommendations do you think is fair? I’m debating between 3 and 5… but can’t decide if it should be overall or per category. What do you think?
December 10, 2024 at 5:30 PM
Planning to drop one last big update to Leisurist before the year’s out—custom recommendations with AI! Let's see if this improves the conversion rate to premium!

Me: "I’ll just add a small feature to Leisurist today."

Also me, 5 hours later: "Why isn’t this building anymore?"
December 9, 2024 at 4:30 PM
Two more weeks of work and then… holidays! Or, well, “holidays” because I’ll just be working on my iOS apps instead of my 9-to-5. Let’s gooo!
December 9, 2024 at 11:50 AM
I love seeing how do users interact with my app!
December 8, 2024 at 6:00 PM
165 new followers since June might not seem like much, but to me, it’s a big deal. This is just the beginning—new updates and apps are on the way. Thanks for being part of the journey!

🤖 After the widgets update, I’m excited to share that AI is coming to Leisurist! 🎉

Working on personalized recommendations based on your ratings. Here’s a sneak peek of what’s next! 👀
December 7, 2024 at 4:00 PM
The last Leisurist update is here! After weeks of fighting with SwiftData, widgets are now live—track and mark the next episode of your favorite series directly from your home screen.

Update now and give it a try! Let me know what you think!
December 7, 2024 at 11:10 AM
SwiftData: "Your model is fine." Also SwiftData: "Crash on launch because I felt like it."

Yeah, this is the last app I’m using SwiftData for, at least for the moment.

In parallel to Leisurist, I'm implementing Dijkstra’s algorithm in Metrociego to calculate accessible routes between stations. Just one edge case left to fix!
December 6, 2024 at 11:30 AM
So… how difficult is it to train a custom movie recommendation model? Asking before I dive in and lose my sanity.
December 5, 2024 at 3:04 PM
Tomorrow I’m starting to integrate AI into Leisurist using ChatGPT (and maybe borrowing some ideas from WrapFast by @juanjovn). Let’s see if I can teach it to recommend content without breaking everything (which is easy with Swift/SwiftUI)
