Comparing PNG, JPG and their optimised versions... to be honest they all look the same, which is pretty good news for my app size!
So many ios26 beta-2 bugs related to liquid glass. This one is especially weird. #ios26 #liquidglass
I think I like the new Icon Composer much more than I expected I would.
India is my second biggest country in terms of downloads, but it generates close to nothing in revenue. Not sure what's going on there.
My new hobby is impulse buying external external storage.
Regardless of the tool, I always end up creating terrible looking - but very colorful - artifacts when debugging.
Coming up soon: quick start a workout. Pretty happy about this one, but it was a nightmare to figure out compared to just setting up predefined workouts.
Do your previews tend to look like a weird flag, or is it just me?
Always pretty cool to see that my boxing app is used worldwide!
Taking the extra few minutes to build a bit of tooling goes a long way. In this case I've added a few commands to define the profile of a user in order to get my preview to display different recommendations. Took me 10 minutes, but it's much more pleasant than fiddling with parameters in the code.
I'm continuously shocked by how exponentially worst Google Search has become over the past few months. It's mostly irrelevant paid content, SEO optimised nonsense and outdated infos. eg: I was looking for the name of a famous photographer, and I was getting served sites about the new iPhone camera.
Coding in 2025 is knowing that if your IA is telling you to compute the pixel height of your font to limit the line count, it's probably not a good idea to listen.
My 2025 design revelation is remembering that semi bold exists.
I have the feeling that this might be a bit too verbose...
I was stressed out by the new workout layout for my app. It's been mostly the same for the past 4 years with minimum complaints from users. However it was getting too cluttered and hitting some flexibility limits so I had to change it. After 1 month in production, survey results are in!
New side project with the tech stack I enjoy the most!
It's not much, but it's always scary to revamp the main screen of your app! There are also many tradeoffs behind a seemingly trivial change.
Clearly MistralAI's Le Chat is the superior AI, recommending the superior boxing app 🙃
"This method is unnecessary and shouldn't be used" Hm... ok?
