Gainset uses your sessions to work out what’s due today: load, reps, sets and rest. Every target has a “Why?” with the numbers behind it.
How it worksMost apps take notes. Gainset closes the loop: every session sets the target for the next one, and your day shapes today’s session.
A check-in before training, one question per screen, done in 30 seconds. If you like, HRV, resting heart rate and sleep join in. The score is measured against your own last 28 days, never against other people’s average.
Load and reps sit large in the middle; rest, RIR and “Complete set” at the bottom, where your thumb is. The screen stays on while you train.
Once you save, Gainset computes the next session from this one: more load if you reached the top of the rep range, the same load if you didn’t. Gainset spots when a deload is due, when you plateau and when you return after a break, and suggests what to do. You decide.
Estimated max (e1RM) and trend per exercise, a Strength Score across your movement patterns, records that follow from your history. Every screen starts with a sentence, and the chart shows it.
Every target follows fixed rules you can look up. Tap “Why?” to see what it is based on.
The engines compute, the AI Coach only explains. Every AI answer is checked against the engines’ numbers; if one doesn’t match, you see the fixed explanation instead. AI text is always labeled.
Everything serious training needs. And nothing that slows you down mid-session.
“Fresh. Bench press goes up to 82.5 kg today.” The first screen says what’s next, with the week strip and your week in the block, your next session and its time budget. For the main lift, “last time” stands beside “today”, with the difference. When a deload is due, it sits right below: every exercise shows its plan and its deload (say, 3 by 8 to 2 by 8 at the same weight), and you choose: deload this week, put it off or train without it. If you just start, that counts as “this week”.
Coming from Strong or Hevy? Import your CSV export. Exercises with history need no starting value; Gainset computes the first target from your past sessions.
Sets per muscle against your range: what you recently handled well. Planning only adds sets from your own history.
HRV, resting heart rate and sleep from Health Connect, Apple Health or WHOOP. Read-only, only with your consent, each category separately.
Load, reps and e1RM – spotted the moment you finish the set, derived from your whole history, imported sessions included.
Daily targets for calories and macros, computed from your trend weight and training. A barcode scanner for packaged food, and over 7,000 staple foods from the German Federal Food Key for everything else.
Trend weight instead of daily swings, body measurements with a plausibility check, progress photos that never leave your device.
The screens are tested with a screen reader and at 200% text size. Contrast meets WCAG, and animations respect “Reduce motion”.
Computed in kilograms, shown in your unit – with bars, plates and increments on your gym’s grid.
Training data says a lot about a person. Gainset treats it that way: encrypted on the device, fully usable without an account, each consent revocable separately.
The engines compute for everyone. Pro unlocks what they decide for every exercise and every week.
Free forever, no time limit.

Prices and trials are shown in the app, straight from the App Store or Google Play.
For people who want measurable progress in the weight room and have been training for a while. If you are just starting, you get a first plan based on your days, equipment and experience – the depth reveals itself with every session.
From your history: load, reps and RIR of your recent sessions, plus your readiness. The rules are deterministic and documented; the same data always yields the same target. Without history, Gainset starts from your starting values or an import.
No. You can accept any target or enter your own load. A deload that is due is already in your next session, but you can put it off or train without it; Gainset learns from what you actually train.
Yes. Training, history, targets and analysis run on the device. You only need a connection to sync with your account, search the food catalog and use the AI Coach.
It puts the engines’ results into words. It decides nothing and never receives raw health values or your name. Every answer is checked against the numbers before you see it. Without the coach, Gainset shows the fixed explanations.
No. Gainset is not a medical device. If you are in pain or have health concerns, talk to a doctor.
