Transformations
Losing weight, losing weight with GLP-1, muscle gain, pregnancy, postpartum recovery and more — eight types, each with its own goal and rhythm. Completed journeys move to the archive and can be revisited or resumed at any time.
Your transformation,
made visible.
Whether you’re losing weight — with or without GLP-1 —, expecting a baby, recovering after birth or building muscle: Formwandel accompanies your transformation with progress curves, guided progress photos — and, at the end, a film that shows your whole journey. Private, no account, entirely on your iPhone.

Features
Everything for your journey. Nothing to distract you.
One entry per day: your values and up to three guided photos. Formwandel turns them into curves, a before/after graphic and a film.
Guided camera
Alignment guides for every photo type, a ghost overlay of your last photo and a self-timer — your photos are always taken from the same perspective.
Apple Watch as remote shutter
iPhone on the tripod, eyes on your wrist: the Watch app shows you the live camera feed and takes the shot at the tap of a button — instantly or with a 3, 5 or 10 second timer.
Today, your way
You decide what counts for each transformation: weight, body fat, waist, baby bump, BMI, muscle mass or steps — as a tile with the current value or as a progress curve with goal line and streak badge.
Studio: film & before/after
Your photos become a film with smooth transitions — date, value and curve run along in the picture. Or create a before/after graphic to share in seconds. Rendered entirely on your iPhone.
Apple Health
The weight from your smart scale is picked up automatically as an entry. Your entries are written neatly to Apple Health.
Widgets & reminders
Check-in status and weight curve on your Home Screen, progress on your Lock Screen — plus reminders at the time of your choice.
iCloud sync & backup
Entries, photos, transformations and measurements sync to all your devices via your private iCloud. Plus: ZIP export and restore with merge.
For every journey 
One app, many transformations
Formwandel is more than a weight-loss app: when you create a transformation, you choose where your journey is headed — from GLP-1-assisted weight loss to pregnancy. The app adapts values, curves and film accordingly.
Losing weight
Set a goal weight, follow the curve with its goal line, keep your streak — and capture every bit of progress in photos.
Losing weight with GLP-1
Supporting your weight loss with a GLP-1 medication such as Wegovy or Mounjaro? Log every dose in mg on your own schedule — the dose appears in your entries list, in the film and in the success graphic.
Pregnancy
The current week of pregnancy right on your Today screen, your baby bump circumference as its own progress curve — and, at the end, a film that tells nine months in seconds.
Postpartum recovery
Back to your own shape after birth: postpartum recovery is its own transformation type with fitting values and no pressure on rhythm.
Muscle gain & bulking
Upwards is a direction too: muscle mass and weight as curves, plus progress photos that make your gains visible.
Maintaining & custom goals
Maintain your weight after a diet or define a goal that’s entirely your own — you configure values, tiles and interval freely.

A look inside the app
Four tabs, one goal: keep going and see the change.
Your day at a glance: your values as tiles and curves — with goal line and streak.
Apple Watch
Your remote shutter on your wrist
iPhone on the tripod, app open — from now on you don’t have to touch it. The Formwandel app on Apple Watch shows you the live camera feed and takes the shot when you’re ready.
- Live preview. See your iPhone’s camera feed in real time on your wrist — including alignment guides for the perfect position.
- Shutter with timer. Shoot instantly or with a 3, 5 or 10 second countdown — enough time to lower your arm and get into position.
- Switch cameras. Toggle between front and rear camera, right from your watch.
Studio
Your whole journey in one film
The moment every photo was worth it: Formwandel automatically aligns your photos and lets them flow into one another.
- Collect photos. Face, body front, body side — the guided camera keeps every perspective consistent.
- Align automatically. Face and body detection stack all shots congruently — no manual work needed.
- Configure the film. Portrait or landscape, 15 to 90 seconds, up to three categories as a split screen — with the date and the curve of your choice in the picture, from weight to baby bump. With GLP-1, the dose can run along too. Exports straight to your photo library.
For the quick moment in between: the before/after graphic puts two photos side by side — with perspectives, comparison values and progress curves, ready to share.
Progress
Numbers that encourage you
This is what the curve feels like in the app — your development with goal line and selectable time windows, at a glance. The app does the same for body fat, waist, baby bump and more.

Privacy
Your photos. Your data. Your device.
Progress photos are as personal as it gets. That’s why Formwandel is private by design.

Photos, weights and films stay on your device. Even the morphing for the transformation film is rendered on-device.
No account, no tracking
Formwandel needs no sign-up and no e-mail, and it collects no analytics.
Private iCloud
If you enable sync, your data travels exclusively through your personal iCloud — visible to no one else.
Your backup, your format
A ZIP with JSON, photos, videos, transformations and settings. Export it, keep it and restore it whenever you like.
You’ll find all legal details in the privacy policy of the Formwandel iOS app.
FAQ
Frequently asked questions
Which devices is Formwandel available for?
Formwandel is a native iOS app for iPhone — including an Apple Watch app that acts as a remote shutter with a live preview of the camera feed. You’ll find it on the App Store. We test new features in an open beta first — you can join via TestFlight.
Do I need a smart scale?
No. You can enter your weight by hand in seconds. If your scale writes to Apple Health, Formwandel picks up today’s value automatically.
Do I have to take photos every day?
You decide: daily or weekly rhythm, weight and photos independent of each other. Entries can also be backdated — including imports from your photo library.
Where are my photos stored?
Locally on your iPhone — and optionally encrypted in your private iCloud if you enable sync. There is no server of ours that ever sees your photos.
How is the transformation film created?
Formwandel detects facial and body landmarks, aligns your photos automatically and morphs them smoothly into one another — with the date and the curve of your choice as an overlay, from weight to baby bump circumference. You choose length and format. All directly on your device, exportable to your photo library.
I’m losing weight with GLP-1 — what does Formwandel do for me?
A dedicated transformation type, “Losing weight with GLP-1”: you log every dose in mg on your own schedule. The dose shows up in your entries list, runs along in the transformation film and appears in the before/after graphic — for example “Mounjaro 2.5 mg – 10 mg”. Formwandel doesn’t replace medical advice, but it makes visible how your body changes during therapy.
Can I use Formwandel during pregnancy?
Yes — pregnancy is its own transformation type: the current week of pregnancy appears on the Today screen, in the entries list and in the film, and your baby bump circumference is tracked as its own measurement with a progress curve. For the time after birth there’s the postpartum recovery type.
How much does Formwandel cost?
The complete tracking is free — entries, photos, curves and all transformation types. Formwandel Plus is a one-time purchase with no subscription and expands the Studio, for example with multiple perspectives, comparison values and multi-curves in the before/after graphic.
