Privacy labels are what each developer told Apple, and Apple doesn’t verify them. Morph launched in July 2026 and had no ratings yet. The five other apps are free to download on the US App Store. Pip Body Scan is coming soon to the App Store, for iPhone, and needs a membership to see your results.
How we ranked
We ranked on where your photos end up. Apps that keep every photo on the phone with no account come first, then apps that can sync to your own iCloud, then an app that needs an account, and last an app that sends photos to a server. Within each group, the app whose App Store privacy label lists fewer kinds of data comes first, then the one with more US ratings. That puts Pip Body Scan at the bottom. This compares declared data flows, not security we have independently tested; fewer privacy-label categories do not prove an app is safer.
How to read an App Store privacy label
Every App Store listing has an App Privacy section filled in by the developer. “Data not linked to you” means the developer says it can’t tie that data to you. “Data used to track you” means it may be combined with data from other companies’ apps and websites. Apple doesn’t check these answers, so read the privacy policy too.
On-device storage also means you need a way to keep a copy: Body Tracker says deleting the app deletes its photos, and recommends exporting them before changing phones. A label covers the whole app, not just photos. ZOZOFIT’s ordinary scans process photos on the phone; optional support uploads are separate. Its label also lists usage data used for tracking and health data linked to an account.
Why Pip Body Scan sends photos
Pip Body Scan’s 3D body is made in the cloud. After you agree, your four photos go through Pip’s server to Meshy, which builds the textured 3D body, and copies with the head masked go to OpenAI for the estimates. Meshy’s copy is deleted once the body is saved on your iPhone. If you don’t want any photo to leave your phone, choose Morph or Body Tracker.
- Your record is stored on your iPhone with iOS file protection and left out of backups. There’s no account and no iCloud sync.
- Pip says it doesn’t sell body photos or derived body-shape data, or use them for advertising.
- 3D share links hide your face, keep measurements off by default, expire, and can be revoked.
- “Delete all Pip data” wipes the phone and asks the server to delete the Meshy and avatar copies.
