Turns out I'm motivated by little green squares. I code every day just to keep my GitHub streak alive, so I thought: why not use this power for good? Now I have a heatmap widget on my home screen for going to the gym. Watching those green squares pile up hits different than any fitness app I've tried. It's shallow, but it works. I got fed up with existing habit trackers—too many had subscriptions for what's basically a calendar with colors. So I built this in a month while learning Swift. It's my first native iOS app (I usually work on boring B2B apps), and I'm honestly impressed with how smooth SwiftUI made everything. Features: * GitHub-style heatmap widgets * iCloud sync * Everything stored locally, no accounts * One-time purchase (because I refuse to add another subscription to my life) The green squares now guilt me into working out. Mission accomplished. My goal: keep building apps until I can afford an Apple Vision Pro. If you want to support me, check it out! App Store: https://apps.apple.com/app/habit-heatmap/6747598515
