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.

SET 01The coach that waits to be asked·PREMIUM

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.

01

You ask, it answers

One tap, one read. The rest of the session is yours and it stays quiet.

02

It read everything anyway

Loads, reps in reserve, eight weeks of history and today. Ready for the second you want it.

03

Silence is the default

No notifications, no cheerleading. If you never ask, you train in peace and the numbers still land.

SET 02Periodization, automatic

The routine writes itself.

Linear · free Wendler 5/3/1 · Premium

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.

WEEK 01BLOCK PROGRESSIONWEEK 11
SET 03The number nobody else computes

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.

SET 04Basement-proof · A scoreboard, not a wall
OFFLINE-FIRST

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.

NO SERVICE · STILL LOGGING
SOCIAL LAYER

A club, not a feed.

No infinite scroll of other people’s abs. A scoreboard, a small circle, routines you send by link and workouts you can post anywhere. All of it free.

PRIVACY

E2E encrypted chat

Direct messages nobody else can read. Private accounts and asymmetric follows: being followed is not being watched.

SET 05Field notes·EXAMPLE

What a season sounds like.

I stopped guessing what to load. Week seven, the bar said 85 and I had no reason to argue.
96 KGLINEAR BLOCK · WEEK 07
It never speaks first. I tap when I want a read, and one thing comes back. That one thing is usually right.
71 KGCOACH · ON DEMAND
I am 78 kg and the guy above me is 104. Same table, and the number says he earned it. That I respect.
78 KGRANKING · ONE TABLE
Basement gym, no signal. The session synced when I got upstairs. That's the whole review.

SET 07Straight answers

Before you ask.

Is it really free?

Yes. Free, no card, no time limit: logging, routines, history, linear periodization and the full social layer. Premium, Analytics and Cosmetics are optional one-time purchases; only Featured is monthly.

Do I need a subscription?

No. Everything you buy, you buy once. Featured is the only monthly extra, it is marked as such, and you can ignore it forever.

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.
