THE WORKOUT TRACKER FOR SERIOUS LIFTERS
Log every set in seconds with last week's numbers right beside you — plus smart progression, automatic PRs, and a rest timer that keeps running even when your phone is locked.
LOGGING THAT KEEPS UP WITH YOUR WORKOUT
Type your first set and it fills the rest. Tap a number to overwrite it instantly. Last week's weight, reps, and RPE sit in the PREV column so you always know what to beat.
Mark a set done and the bar checks off — no menus, no friction, built for sweaty hands between sets.

NO MORE GUESSING HOW MUCH TO LIFT

Agree? Apply it in one tap. Prefer your own plan today? Just log your numbers and the suggestion steps aside. Your training, your call.
You hit the top of your rep range three sessions in a row — time to add weight.

FREQUENTLY ASKED QUESTIONS
Can I edit a workout after I've finished it?+
Yes. Open any past workout and adjust the weight, reps, or sets — your personal records and estimated maxes recalculate automatically to match.
Can I log RPE and RIR?+
Both. Tag each set with RPE (rate of perceived exertion) or reps in reserve — switch modes per exercise — and the app carries your intensity history forward session to session.
How does it detect personal records?+
When you finish a workout it automatically scans for PRs — estimated 1RM, heaviest single, best set volume, session volume, and rep records — and surfaces anything new, including first-time lifts.
Does it sync to Apple Health or Health Connect?+
Yes. Completed workouts are written to Apple Health on iOS and Health Connect on Android, and edits or deletions propagate so your health data stays accurate.
Is there a free trial?+
Yes. Cornerstone Strength is free to download and starts with a 14-day free trial — full access, no limits. After the trial, a subscription keeps everything unlocked.
