Progress isn't a feeling. It's a number that goes up.
A coach that answers when you ask it, periodization that writes next week for you, and a leaderboard where 68 kg and 105 kg finally compare — because the score already divides by what you weigh.
Ittalkswhenyousay.
Every other app talks over your set. This one waits. Tap once and it tells you the load for the next set, reading eight weeks of your training, not a template someone printed in 1997.
You ask, it answers
One tap, one read. The rest of the session is yours and it stays quiet.
It read everything anyway
Loads, reps in reserve, eight weeks of history and today. Ready for the second you want it.
Silence is the default
It says nothing while you train. If you do not ask, you train in peace and the numbers get logged anyway. The only thing that may reach you is a nudge if you stop training for weeks, and you can switch it off in settings.
The routine writes itself.
Pick linear or Wendler 5/3/1 once. From then on the loads move on their own, week after week, adjusted by what you actually lifted — not by what the plan hoped you would.
The strongest lifter in the room is not the heaviest one.
Your score is your volume divided by your bodyweight to the two-thirds. A 68 kg lifter and a 105 kg lifter land on the same table, and the number already made it fair. One leaderboard, everyone in it.
What a season sounds like.
I stopped guessing what to load. Week seven, the bar said 85 and I had no reason to argue.
It never speaks first. I tap when I want a read, and one thing comes back. That one thing is usually right.
I am 78 kg and the guy above me is 104. Same table, and the number says he earned it. That I respect.
Basement gym, no signal. The session synced when I got upstairs. That's the whole review.

Before you ask.
Is it really free?
Yes. Free, no card, no time limit: logging, routines, history, linear periodization and the full social layer. GainzAI Pro is optional at €4.99 a month; Analytics is a one-time €9.99 buy if you only want the numbers.
What does Pro add over the free app?
The AI coach, the routine generator, the Wendler 5/3/1 engine, full analytics and the featured profile, which is what puts you in the global and national rankings. Training, logging and the social layer do not need Pro and never will.
Does it really work offline?
Yes. Sessions, timers and history are local first. Losing signal mid-workout changes nothing; sync resumes on its own later.
How does the ranking work?
Your score is training volume divided by your bodyweight to the power of two thirds, the allometric scale. There are no weight classes: everyone shares one table and the maths does the levelling.
Add weight. Not excuses.
Free on Google Play, no card. Set the coach to the volume you can stand and let the numbers do the arguing.
Builtfortheroomswithnosignal.
Train with the antenna dead.
Logging, timers and your whole history work in a basement with zero bars. Signal comes back, everything syncs. You never lose a session.
