The log

What Ratio holds for you

You open the app, you lift, you leave. The rest is written down.

Today’s session is waiting

Its exercises, its sets, the loads you used last time. One button to start — or an open session, picked as you go.

Everything is written down

The history of every session, your loads, your records and estimated 1RM, your attendance week after week.

Offline, in the gym

The session runs with no network — a basement, a gym with no signal — and syncs on your way out.

Lock screen

The session goes on,
phone locked.

The rest timer, the current set and its load stay on the lock screen. You log a set without reopening the app, and shorten a rest by fifteen seconds with your thumb.

And if the gym has no network: the session runs anyway, and syncs on your way out.

Program

Your program,
balanced per muscle.

A few questions — where you train, your equipment, your days, the muscles to emphasize — and Ratio builds the program, balances the volume per muscle group and fills it with your loads.

Or no program at all: start a session whenever you want, pick your exercises as you go, Ratio remembers everything.

Smart progression

It picks your loads,
and corrects live.

For every set, Ratio sets the load and the rep range — from what you actually lifted last time, not from a generic table. The warm-up is calculated on it.

Then it corrects during the session: two reps more than planned and the target for the following sets goes up; fewer, and it goes down. And if you would rather decide yourself, smart progression switches off.

Questions

What you need to know

Yes. Programs, sessions, smart progression, history, records, strength standards and sharing: all of the training side, with no limits and no crippled tier. The subscription only unlocks what costs us AI — the assistant, and body-fat analysis from a photo.

No. Start an open session and pick your exercises as you go; Ratio remembers everything. If you want one, a program is built in a few questions — where you train, your equipment, your days, the muscles to emphasize.

From what you actually lifted in your previous sessions, exercise by exercise — and it adjusts the targets during the session based on the set you just finished, in both directions. You can switch smart progression off and decide yourself.

Yes. The session runs entirely offline and syncs on your way out. A gym with no signal changes nothing.

Yes. The rest timer, the current set and its load stay on the lock screen: the checkmark logs the set, −15 and +15 adjust the rest.

Yes. The trial lasts 7 days, then Premium is commitment-free and cancellable from your Apple Account. And the app stays fully usable for training without any subscription.
