Why TransformAI
Your workout app and your body tracker — in the same app.
Workout apps plan sessions. Scan apps give you a number. Habit trackers count streaks. TransformAI keeps what you train and how your body responds side by side, so you can see both move.
Single-purpose apps
One thing, done in isolation.
- Workout apps plan exercises but give no body-composition feedback.
- Photo-scan apps return a single number with no range and no second source.
- Smart-scale apps swing with hydration and ignore what you look like.
- Form feedback usually means uploading video of yourself to someone's server.
- Habit trackers log streaks with no link to training or physique.
TransformAI
Train it. Scan it. Watch it change.
- AI body-fat scan with a range. 1–4 photo angles in, a body-fat estimate with a confidence range, regional breakdown and physique score out.
- Smart-scale fusion. Scale readings from Apple Health or Health Connect are blended with photos, tape and calipers, with a source breakdown and a 7-day smoothed number.
- A coach you can talk to. Tap to talk or type. The AI coach builds a session from what you say and can ask for a quick assessment first.
- Form check for any exercise. Record a set. Pose is analysed on your phone and graded against the exercise's instructions, with per-rep flags and camera-angle advice.
- Progress on four axes. Body, Strength, Flex and Form on one tab, with local clips and an on-device side-by-side reel.
TransformAI is in TestFlight beta on iPhone; the Android app is in development. Everything described here exists in the current iOS build.
How it works
From first scan to a visible trend in five steps.
How the app is meant to be used, week to week.
- 01
Set your goal
Pick what you're after — lose fat, build muscle or maintain — and optionally a skill goal (a first pull-up, a pancake) or a strength goal with a 1RM target.
- 02
Take your first scan
One to four photos, plus weight and any measurements you have. Faces are blurred on your phone before upload. You get a body-fat estimate with a range, a regional breakdown and a physique score.
- 03
Let the coach build the session
Tell the coach what you've got today by voice or text. It builds a session from a library of 870+ exercises with real photos, or a full weekly plan.
- 04
Train and check your form
Work through the session set by set. Record any set for a form check — pose is analysed on-device and you get per-rep flags and camera-angle advice.
- 05
Log habits, watch the trend
Tick off up to four daily habits and re-scan weekly. Progress shows body, strength, flexibility and form side by side.

Features
What's in the app today.
Every feature below is in the current iOS beta build. Nothing on this list is a roadmap item.
Smart-scale fusion
Readings from Renpho, Withings, Eufy, Garmin or Zepp scales (via Apple Health / Health Connect) are blended with photos, tape and calipers. See the source breakdown and a 7-day smoothed number, or log from the scale with no photo.
AI workout plans
Weekly plans and one-off sessions built around your goal, equipment and time, drawing on a public-domain library of 870+ exercises with real photos and instructions.
Voice and text coach
Tap to talk or type what you've got today. The coach builds the session, and can ask you for a quick assessment before it prescribes anything.
Form check, any exercise
Record a set. Pose is analysed on-device — only numbers are sent, never the video — and graded against the exercise's instructions with per-rep flags and camera-angle advice.
Skill and strength goals
Skill roadmaps such as a first pull-up or a pancake, broken into milestones. Strength goals with 1RM targets and 5/3/1 progressions.
4-habit tracker
Up to four daily habits you choose, one tap to log. Streaks per habit and a weekly heatmap show where the week slips.
Apple Health sync
Reads steps, sleep, weight and body fat; writes your workouts, weight and body fat back. On Android the same role is played by Health Connect.
Progress on four axes
Body, Strength, Flex and Form on one tab. Clips are stored locally, and a side-by-side progress reel is generated on your phone.
Private by default
Faces are blurred on your device before a scan photo is uploaded. Form-check video never leaves the phone. Photos stay local unless you turn on cloud backup. No ads. Export or delete your data any time.
How the number is made
An estimate you can see the working of.
No home method measures body fat exactly. TransformAI combines whatever you give it and tells you how sure it is.
1–4 photos
Front is required; side, back and legs narrow the range. A vision model estimates body fat, a regional breakdown and a 0–100 physique score. Photo-only estimates are roughly ±3–5 percentage points.
Smart scale
Body-fat and weight readings that Renpho, Withings, Eufy, Garmin or Zepp scales write to Apple Health (Health Connect on Android) are picked up automatically when they're recent.
Tape measure
Optional waist, hip and other circumferences you enter at check-in give the estimate a second, camera-independent signal.
Calipers
If you take skinfold measurements, add them too. Every extra source you provide is blended in rather than replacing the others.
What you get back
- One fused estimate, with a range. The sources you provided are blended into a single body-fat figure shown with a confidence range — not one falsely precise number.
- A source breakdown. Each result shows which sources went into it (photo, scale, tape, caliper), so you can see why this week's number is tighter or looser than last week's.
- A 7-day smoothed number. Scale readings swing with hydration. A 7-day smoothed value evens that out, so a salty dinner doesn't look like fat gain.
- Log from scale, no photo. On days you don't want to take photos, log a reading straight from your scale. It keeps the trend going between photo scans.
Body-fat figures in TransformAI are wellness estimates, not medical measurements. Accuracy improves when you add a smart scale or measurements and keep lighting, pose and time of day consistent.

FAQ
Frequently asked questions.
Straight answers, including the ones about what is not ready yet.
- Not from a store yet. The iPhone app (version 1.0.0, iOS 17 or later) is in TestFlight beta and the Android app is still in development, so there is no App Store or Google Play listing. To try the iOS beta, email support@transformai.fit and we will send a TestFlight invite when a spot is available.
- You take one to four photos — front is required; side, back and legs are optional. Faces are blurred on your phone before the photos are uploaded, and a vision model returns a body-fat estimate with a confidence range, a regional breakdown and a 0–100 physique score. If you also have a smart scale, tape or caliper measurements, they are blended into the same estimate.
- Treat it as a wellness estimate, not a medical measurement. From photos alone, expect roughly ±3–5 percentage points. The estimate improves when you add more angles, a smart-scale reading or tape and caliper measurements, and when you keep lighting, pose and time of day consistent. The app always shows a range rather than a single falsely precise number, and the trend across weeks is more useful than any one reading.
- Yes. The free tier includes 4 AI body-fat scans per month. Logging a reading straight from your smart scale does not use a scan. TransformAI Pro removes the monthly scan limit.
- In the current build Pro is $6.99 per month, $39.99 per year (about $3.33 per month) or $79.99 once for lifetime access. Monthly and annual subscriptions start with a 7-day free trial. Prices are confirmed at purchase by the App Store and may vary by region.
- Any scale whose app writes body fat and weight to Apple Health on iPhone — for example Renpho, Withings, Eufy, Garmin and Zepp. TransformAI reads the latest reading from Apple Health; on Android the same role is played by Health Connect. You can also log a check-in from the scale without taking a photo.
- Record a set of any exercise. Your body pose is analysed on the device, and only the resulting numbers — joint angles and rep measurements — are sent to be graded against that exercise's instructions. You get per-rep flags and advice on camera angle. The video itself never leaves your phone.
- You tap to talk or type what you want — for example how much time you have, what equipment is around and what feels tight. The coach builds a session from a library of more than 870 exercises with real photos, and it can ask you to do a quick assessment first. It also generates weekly plans, skill roadmaps such as a first pull-up or a pancake, and strength progressions based on 1RM and 5/3/1.
- Faces are blurred on your device before a scan photo is uploaded, and the scan is processed through our server by OpenAI's models. Progress photos are stored locally on your phone unless you opt into cloud backup. Form-check video never leaves the phone. There are no ads. You can export your data and delete your account from Settings.
- Yes, if you grant permission. It reads steps, sleep, weight and body fat, and writes your workouts, weight and body fat back to Apple Health.
- An Android app is in development and not yet available. It is a native app that mirrors the iOS features and uses Health Connect in place of Apple Health.
