A full training diary for Android and the browser. Log any exercise with weight, reps and effort, follow 12-week plans for bench, squat and deadlift, watch your progress in graphs — and export the whole diary for your AI assistant.
Three tabs: TRAINING, PROGRAM and PROGRESS — a diary, smart plans and your trend in one app.
Log any exercise, free-form — weight, reps and effort 1–5 per set. Today's session, your way, in seconds.
Add anything — cable pulldowns, curls, farmer's walks. Add it once and it stays in your list.
Estimated 1RM and training volume over time, per exercise. Watch the trend, not a single day.
Export the whole diary to JSON, ready to hand to your AI assistant — have it analyse your training and suggest what's next.
Bench, squat and deadlift — each with its own test, its own plan and its own history. Weekly increments tuned per lift.
What you can lift for 1 through 15 reps. Above 10 reps shown as an honest range (two formulas), not false precision.
Log a set and the rest countdown starts by itself — it remembers your rest length per exercise and vibrates when time's up. Survives app switches and the lock screen.
25 questions & answers on muscles, strength, recovery and mindset — including why you shouldn't test your calculated max today, and how to reach a new PR safely.
No cloud. No signup. No tracking. Your data stays on your device. Works fully offline.
Switch language with a single tap. Both translations crafted by lifters, not Google Translate.
From today's session, to your 12-week plan, to the long-term trend.

For anyone who wants their training written down and understood — a diary for every exercise you do, and deliberate 12-week plans for the big three. Beginners get structure; advanced lifters get history, trends and data their AI can chew on.
