About this app

Everyone deserves simple, lightweight tools.

I built this app because I wanted to log my workout and move on with my day. No sign-ups. No subscriptions. No nonsense. Then I thought — maybe others want this too.

◉ Open the app.
◉ Tap your workout type.
◉ Hit "Log Workout."
◉ Done.

Want to see what you did last Tuesday? Open the calendar. Tap the date. There it is.

What this app does NOT do:

✗ No accounts or sign-ups
✗ No internet connection needed — ever
✗ No ads, in-app purchases, or subscriptions
✗ No data collection of any kind
✗ No remote AI processing or cloud-based data selling

Your data stays on your device. Period.

Features:

• Ultra-lightweight (under 3MB) — installs instantly, negligible battery use
• Log workouts with one tap — Cardio, Gym, or any preset type
• Pick a date and time, or just log "right now"
• Swipe to delete, with undo
• Monthly calendar view and rolling 7-day weekly view
• 100% open-source & offline — code is auditable on GitHub
• Worry-free device switching — securely backed up to your Google account
• Android 16 AppFunctions integration — let your on-device assistant log workouts and query history locally
• Material You theming with light and dark mode

This app does one thing and does it well.
If you're tired of bloated apps — this is for you.
