Comparing PNG, JPG and their optimised versions... to be honest they all look the same, which is pretty good news for my app size!

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 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!

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.
