Building My Own Pixel Art Workout Widget after BJJ, Running, and Weight Training

They say you should exercise at least 30 minutes a day, 3 times a week to stay healthy. I practiced Jiu-Jitsu (BJJ) for a long time, and these days I work out 5 days a week for about 40 minutes each session, while also running regularly.

As I engaged in various sports, I often thought: 'Wouldn't it be great if tracking my workouts felt more fun and visual, rather than just plain numbers and text?' Talking with fellow fitness enthusiasts, I realized many people wanted a light, hassle-free way to log attendance alongside customizable widget spaces tailored to different sports.

That's how Sportling was born—an app where you can showcase your own cute pixel art workout space, easily check in daily, track D-Days, and feel a genuine sense of accomplishment right from your home screen.

2. Daily Attendance & Visual Heatmaps

Check off your daily workouts with a single tap. As time goes on, your consistency fills up a heatmap calendar—giving you a visual sense of achievement every time you look at it.

Forgot to log yesterday's workout? No problem. You can retroactively record past workouts whenever you want.

Closing Thoughts

Although I started building Sportling for my own personal needs, I hope it brings a smile and a small sense of accomplishment to anyone who loves staying active.
