Quick start

1. Create a weighing profile when you first open the app.
2. Open Weigh, tap “Add your first scale,” and allow Bluetooth access.
3. Wake the scale near your iPhone and select the detected device.
4. Stand barefoot and still until weight and impedance lock. With socks, many scales provide weight only.

Compatibility labels

• Hardware verified: reproducible end-to-end evidence exists for this protocol family. Version 1 verifies two QN/Yolanda GATT scales owned by the developer.
• Community verified: an external user supplied evidence for the real model.
• Awaiting field test: protocol code and test vectors exist, but that retail model has not completed hardware acceptance.
• Not currently supported: iOS or device-protocol constraints prevent reliable direct connection.

Check the complete model and evidence label under “Me → Supported Scales.” Do not rely on brand alone.

Troubleshooting

The scale is not found

• Turn on Bluetooth and allow MantaScale to use it in iOS Settings.
• Keep the scale awake, place the iPhone nearby, and quit other apps connected to the scale.
• Wait for a complete scan; if needed, enable “Show all Bluetooth devices” for troubleshooting.

The scale appears but weighing does not complete

Check the complete model on the scale label. Some encrypted scales require the lawful bind key, Bluetooth address, or initialization in the manufacturer’s app. MantaScale does not bypass manufacturer authentication.

Why do I see weight but not body fat?

Body-composition estimates usually require impedance plus valid height, sex, and date of birth. Stand barefoot on the electrodes. Weight-only scales do not produce body-composition results.

Why is a record awaiting confirmation?

If a new weight differs greatly from the current member’s recent baseline or resembles another household member, MantaScale does not guess. Select the correct member or delete the pending record.

Why does Apple Health require a separate owner?

Apple Health normally represents the iPhone owner. Explicitly select that person’s MantaScale profile before importing or enabling automatic writes.

Before uninstalling or changing phones

Export CSV or JSON from “Me → Export Data” and save it outside the app. Version 1 has no account or cloud sync, so reinstalling does not restore deleted local records.

Restore a purchase

Open “Me → MantaScale Pro” and choose “Restore Purchases.” Apple handles payment, refunds, and purchase history.

Contact support

Email support@axonlume.com with the MantaScale version, iOS version, iPhone model, complete scale model, the affected stage, and brief reproduction steps. Do not send unrelated names, dates of birth, or complete health records.

MantaScale provides consumer body-composition estimates, not medical diagnosis, emergency service, or treatment advice.
