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.

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.

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 It's mostly irrelevant paid content, SEO optimised nonsense and outdated infos.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.

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!
