Stacked — strength training, dealt daily

Field notes

Stacked maps strength progress onto a card-deck system: each movement receives a rank, and the deck becomes the visible progress bar. The policy describes local storage for exercises, history, badges, equipment, places, and settings, with optional on-device location and Apple Health export for workouts, heart rate, and outdoor routes. The site says the app works offline, has no account or tracking layer, and is planned for a $9.99 one-time App Store purchase.
