The coach that carries you through it.
A plan is easy. Doing it is the hard part, and that's the part PT‑One carries you through. It speaks each exercise, counts you in, times every rep, hold and rest, and tells you when to switch sides. Your phone stays in your pocket. You just follow along.
Press play. Follow the voice. Do your exercises.
Whatever app you came for, it's in here.
"I just want a simple gym tracker. Nothing else."
IT'S IN HERE. Sets, weights, PRs, history. Zero taps. Crack on.
"I want it all done for me. Designed, tracked, pushed."
IN HERE. Petra designs it, runs it, and nudges when it's earned.
"Ready-made plans I just press play on."
IN HERE. Programs, targets, challenges. The maths already done.
"Circuits, EMOM, AMRAP. I train hard."
IN HERE. Timed, spoken and scored. Benchmarks included.
"I'm rebuilding after an injury."
IN HERE. It's where PT‑One began.
"Honestly? All of the above."
That's the point. ONE APP. For you, and you, and you.
It speaks. You move. That's the whole deal.
Mid-stretch, on the floor, hands full: that's exactly when tapping a phone fails you. PT‑One runs the session for you, out loud, from the first "get ready" to the last "done".
- Every move announced: the exercise, the form cue, the count-in.
- Every rep and hold timed: rests handled, both sides guided one at a time.
- Talk back: "Petra, log eight" · "skip the rest" · "where are we?" Logging and control by voice, mid-set, with chalk on your hands.
- On your wrist too: the whole session runs on Apple Watch with heart rate logged, while the phone charges in another room.
"Petra. 12 Reps!"
Every format. Every pace. Your rules.
Straight sets, timed holds, flowing circuits, every-minute rounds, benchmark AMRAPs, and the same calm voice runs them all. However you train, PT‑One already speaks it.
- Edit mid-session: swap an exercise, add a set, change a weight while it runs. The session bends; it never breaks.
- Supersets & drop sets: paired work runs back-to-back in lockstep, spoken.
- Long efforts get a clock: a 5k row runs as a proper MM:SS clock with overtime, not a kitchen timer.
Honest is a feature.
PT‑One cheers you loudly: PBs, medals, streaks, the final-set push. And it never fakes one. No invented scores, no confetti for logging in, no new number to keep on top of. When this app celebrates, it's because you did it.
And when there's nothing true to celebrate? Silence. That's why you can believe the rest: the numbers, the streaks, the price. Honesty, always.
Show up. The numbers are already set.
Programs handle the arithmetic: what to lift today, when to add weight, when to hold steady. Targets turn a goal into a numbered route. Challenges give a month a shape. Your job is the reps; if life gets in the way, the plan bends. It never guilt-trips.
- Built to your goal: get-stronger, build-muscle and keep-moving programs are genuinely different: different lifts, different shapes, different numbers.
- Progressive overload, explained: a nudge when a lift has sat still, and a plain "why" behind every suggestion.
- Multi-week, lighter week built in: from ready-made classics to programs Petra builds around you, your kit and your days.
Targets
"Get stronger" isn't a plan. "Session 9 of 24 on the road to your first chin-up" is. Pick the goal, see the whole route before step one.
Challenges
One clear thing a day for a month, or your normal week, planned and kept. Life intervenes? It pauses and extends. The only way to fail is to stop forever.
See what's ready before you train.
Every session paints a body map: which muscles you worked, and how recovered they are now, on a clock you control rather than a formula we hide. Glance before you train and pick the day that fits: legs are fresh, chest needs another day.
- Pain, tracked, never diagnosed: where it hurts, how much, alongside what you trained. Patterns land in your data, not your memory.
- Sessions that respect it: flagged areas ease the plan and rank kinder swaps first, with a plain reason every time.
- A weekly review worth reading: sessions, records, muscles worked and honest observations. Silence on a quiet week; that's the trust.
Muscle recovery, visibly
What you hit, what's ready, what needs another day. One glance, then train. The recovery clock is yours to set, not a formula we hide.
The weekly report
Your week's sessions, records, muscle work and plain-language observations, with charts you can actually read. Silence on a quiet week; that's the trust.
7 Day Health
Steps, exercise minutes, resting heart rate, sitting time, benchmarked against evidence rather than vibes. No score, no lecture.
Form check
Film a set and Petra coaches it: what's working, what to correct, what to try next. Affirm, correct, progress.
Never interpreted, always shown
PT‑One shows the data and lets you draw the conclusions. If a number would be a guess, there is no number. That's a promise, not a limitation.
1,800+ exercises. Filtered to what you actually own.
Tell PT‑One what you've got: a full rack, a pair of dumbbells, or nothing but floor. Everything adjusts: sessions built from your kit, swaps suggested from your kit, nothing prescribed that you can't actually do. Hotel gym this week? Say so, and the plan reshapes itself.
- Search it any way: by name, muscle, kit or bodyweight; slide the A–Z to jump straight to the move you're after.
- Real detail: instruction, animation and muscle maps on every move, so nothing feels bolted-on.
- Honest matching: respects your kit, your pain and what you've marked "not for me". What you see, you can actually do.
Custom kit, built from a photo
Bought something the library's never heard of? Photograph it and tell Petra what it is. She makes it a real piece of kit and researches a set of exercises for it, muscles and instructions included. It won't feel bolted-on, because it isn't.
Your gyms, from photos
Snap your garage or the hotel basement and Petra lists what's in view. Your gym builds itself. Home rack, full gym, or nothing at all: every session reshapes to the kit that's actually there.
Point it at a machine
That machine you've never dared touch? Photograph it and see every exercise it can do, with instruction and muscle maps. The intimidating corner of the gym, opened up.
Find anything, instantly
Pull down on any main screen and search the whole app: exercises, kit, programs, settings, even "where do I change the wake word?" Torch takes you there and lights up the exact control when you land.
Made to be shared
Send a whole session as a link or QR: a client, a parent, a friend just presses play. "For someone else" folders keep their plan, history and progress cleanly apart from yours.
Ask for a change. Get a session.
Petra is the coach inside PT‑One: ask her to build a session for the kit you have, swap an exercise that isn't working, or explain why today looks the way it does, and the answer lands as a real, playable session, not a paragraph of advice.
Yes, Petra is AI, used the honest way: no account, your questions travel nameless and aren't kept, her answers land as sessions you can edit or undo, and she never tells you to push through pain.
- Works the moment you install: no key, no account, no set-up.
- Everywhere she's useful: in your session for hands-free logging, on every routine for chat-edits, behind the weekly review, building custom moves.
- Honest about what she is: never tells you to push through pain, and hands the wheel straight back after every change.
Your training data isn't our business model.
Your sessions, your history, your pain notes: all of it lives on your iPhone, backed up sealed to your Apple ID. No account to create, nothing to harvest. Ask Petra for help and even that stays nameless: your question travels with no identity attached and isn't kept. She answers; it's gone.
We built it this way because we'd want it this way.
The plan was never the problem.
Doing it was.
PT‑One runs your session out loud: every rep timed, every move spoken, hands-free from first stretch to full strength. In TestFlight now, public launch soon.
