In the gym
You’re standing at a rack with chalk on your hands. Thrive is built for that moment, not for studying dashboards at a desk.
01
Open the session and every row is pre-filled with what you lifted last time. No scrolling back through a notebook to remember whether it was 20 or 22.5.

One tap logs the set and starts the rest timer. Big targets, no keyboard, nothing to think about while you're still catching your breath.

Swap between the day’s exercises, check the movement notes, add a set, or minimise the whole thing and pick it back up after a phone call. It survives you leaving the app.
A little stronger. A little more you.
Progress
Progress in the gym is slow enough that you can’t feel it week to week. Thrive keeps the receipts, so twelve weeks of work becomes a line instead of a hunch.
Dumbbell bench press
Pick a lift and Thrive plots your estimated one-rep max from every set you’ve logged of it - so a heavier set for fewer reps still counts as progress, and a lighter week doesn’t read as failure.
It’s the Epley estimate, the same arithmetic strength coaches have used for decades. A yardstick for comparing your own sessions - never a weight to go and attempt.
Every session totalled the moment you finish it.
How often you actually showed up, over the last four weeks.
What each day asks of you, and what you've already ticked off.
Your programme
Your goal, your equipment, the days you’ve actually got and the muscles you want to prioritise. Thrive turns those answers into a training week you can start tomorrow, plus the energy and protein targets to support it.

Your targets
Smart, not mystical
Your routine comes from your equipment, experience and time per session. Your targets come from published energy equations and the history you log. Every calculation runs on your iPhone - no account, no upload, no one else reading your numbers.

Nutrition
You can log every set perfectly and still stall. Thrive sets your energy and protein around the goal you’re training for, then keeps them honest as your weight moves.

One weigh-in is noise - water, salt, sleep, timing. Thrive averages across the weeks so you see the direction you’re going, and how far it is to where you said you wanted to be.
One system
A training plan is a guess until something checks it. Thrive closes the loop: logged sets become your strength history, weigh-ins correct your energy target, and next week moves with you instead of going stale by week three.
That’s the part a folder of separate apps can never do.
Train
Every set you log says what you did.
Measure
Your history says what's working.
Fuel
Your targets support where it's going.
And round it goes.
Details
Built the way iPhone apps are meant to be built - so it fits however you have your phone set up.
No before photo. No fresh start on Monday. Log one meal, do one session, and let the line do the talking.
