The coach that sees your form
BNK Fit watches your movement through your phone camera: it counts your reps, measures your depth and corrects your mistakes with real-time voice coaching. No extra hardware — prop up your phone and go.
In development for Android and iOS. It will be right here on launch day.
*yes, zero
Camera on, form under control
Your phone camera watches the movement; BNK Fit measures joint angles in real time. Shallow reps don't count, movement in the wrong plane gets flagged — exactly what a good coach at the gym would do.
- Live skeleton and angle tracking — the joint you need to fix is marked on screen
- Invalid rep detection — shallow, rushed or wrong-direction reps are rejected with a reason
- Voice depth coach — hear "go lower" without looking at the screen
- Processed on device — the camera feed never leaves your phone
20 minutes, hands off the screen
One tap, and the rest takes care of itself: exercises flow one into the next, the countdown runs, voice narration guides you. The music ducks itself whenever the coach speaks.
- Guided sessions — starting with a 16-step stretching flow, more on the way
- Real studio voice-over — bundled on device, works offline
- Workout music — automatically ducks under the coach's voice
- Camera on demand — one tap adds form checking on scorable steps
Mention an injury, watch your plan change
The moment you flag a knee injury, you see exactly which exercises leave your pool. That's not an animation: the program engine genuinely removes them — and tells you why.
- Injury → exercise filtering — removed and remaining exercises shown with proof
- Built around your equipment — works with nothing but bodyweight, or with bands and dumbbells
- Goal + level + time — your weekly plan is built for you
- "Why" notes — every choice the engine makes comes with its reason
Measurement, not guesswork
Enter your tape measurements and get a US Navy body-fat estimate. When the number isn't reliable, we say so openly — no rounding things in your favor.
- US Navy body fat — clearly labeled as an estimate, right on the result
- Waist-to-height and waist-to-hip ratios — health signals that feed back into your plan
- Progress history — real change from one measurement to the next
- 3D body scan on Premium — your digital avatar and measurements from two photos
Your data is yours. Period.
Trust in a health app starts with how it treats your data. Our rules are written into the code.
Camera footage stays on your phone
Form analysis runs entirely on device. The camera feed is never uploaded and never stored anywhere.
Notifications are local
Reminders are scheduled on your phone and stay on your phone — no data goes to a server to ring a bell.
Health data never enters share texts
When you share a workout, we never include your weight, measurements or body fat. What you share is up to you.
Delete your account in the app
No emails, no forms. One step in Settings permanently deletes your account and your data.
Fake "96% match scores", made-up countdowns, "3 people just subscribed" toasts, personalization claims with nothing behind them… none of that here. We show what the engine actually does, and we tell you what it can't do. Trust isn't our marketing — it's the product.
Your team in shape, their data safe
Give your employees BNK Fit: guided stretching for desk-bound teams, personal programs, form coaching. On the employer side there's a hard line — individual data is never visible.
- Fast activation by code — employees enter a code and their package unlocks; zero setup burden
- Individual data is never shared — employers cannot see who trained or how much
- Aggregate metrics only — participation reports are aggregated, and hidden entirely for small groups
Good questions
We're preparing for the App Store and Google Play. The badges on this page will go live the day it ships.
Just your phone. Prop it upright, step back a couple of paces — analysis starts the moment the camera sees you. No sensors, no wearables, no extra hardware.
Nowhere. Movement analysis runs entirely on your device; the camera feed is never recorded and never uploaded. Details in our privacy policy.
Guided flows and voice narration work offline — the audio is bundled inside the app. You'll need a connection to sync your account and measurement history.
You start free: programs, guided flows and form analysis are open. Basic and Premium packages unlock body measurement tracking and the 3D body scan.
In development for Android and iOS. Form analysis runs smoothly on phones with recent processors (models from the last few years); everything else works on any ordinary smartphone.
Your move
BNK Fit is getting ready for the App Store and Google Play. The coach that sees your form — soon in your pocket.
