Most fitness apps are built around the fear of missing a day. Foundation is built around the reality of living one.
Core features free to use, no credit card required. Wearable sync available with a monthly or annual subscription.
ABOUT
Life is part of the plan, not an interruption to it. Foundation Fitness is built around how real routines work - rest days, schedule changes, and the days you show up anyway. No influencer features, no social feed, just a fast, focused tool that works between sets.
Simple by design.
Powerful by habit.™
BUILD YOUR ROUTINE
Name your workout days, tag them however you want, and load whichever one fits today. Start from scratch or pick a template. Either way, it's yours to customize.
TRACK EVERY SESSION
Check off exercises, update weights, snap progress photos, and log body metrics, all from your phone between sets.
WATCH RESULTS COMPOUND
Review charts, compare photos side by side, and see how showing up consistently turns daily effort into real change.
Built around real life.™
Pick your routine. Check it off.
Each day, tap which workout you're doing. Check off exercises as you go, swipe to add or edit. No menus, no friction.
Create a side-by-side collage to save or share.
CONNECT YOUR WEARABLE (OPTIONAL)
Add the Wearable Integrations subscription ($9.99/mo or $79.99/yr) and your metrics sync automatically: sleep, heart rate, HRV, VO2 max, steps, body composition, and more. Skip it and the rest of the app still works.
More providers (Apple via the iOS app, Peloton, Flo, Biostrap, Under Armour, Google Health Connect) rolling out.
Results vary. Habits don't.™
The app is free. Wearable sync is optional.
Manual entry is free for everyone. Add the Integrations subscription to auto-sync from Garmin, Oura, WHOOP, Withings, and more.
