About this app

StrengthOS is a training log built for people who take the barbell seriously — powerlifters and strength athletes who want to log fast, track real progress, and train on a proper plan.

BUILT FOR THE GYM FLOOR
Logging happens between sets, with chalk on your hands and a clock running. Every set is one tap: weight × sets × reps @ RPE, saved instantly. One exercise in focus at a time — never a wall of tiny inputs.

TRACK WHAT ACTUALLY MOVES
• Estimated 1RM (e1RM) computed on every set, per lift — see your true strength trend, not just what you lifted that day
• Personal records by lift, kept separate for each variation (back squat and SSB squat never get merged)
• Bodyweight log with automatic DOTS score for weight-class athletes
• Clean progress charts across a whole training block

TRAIN ON A REAL PLAN
Browse structured powerlifting programs. Enroll available programs, and the app builds your week-by-week sessions with personalized target weights suggested from your previous lifts. Advance block to block as you progress. Coach-designed paid programs coming soon.

AN AI COACH THAT READS YOUR NUMBERS (Pro — coming soon)
StrengthOS watches your block-by-block data and surfaces what a good coach would notice — a stalling bench, a lift ratio drifting out of balance, an RPE creeping up week over week — in plain language, with what to do about it. The pattern detection is rules-based and auditable; AI writes the explanation, never the numbers.

FREE — NO CARD REQUIRED
Logging your training, tracking PRs, and following programs are free, with no card required. AI training insights (StrengthOS Pro) are coming soon.

Your training data is yours. Export or delete your account at any time from inside the app.

StrengthOS is operated by CloudNamaste Pty Ltd (Australia).
