Most problems are solved below. If not, email the developer and you'll get a reply.
Setup and Bluetooth
My scale won't connect
Check that Bluetooth is on and that SyncScale is allowed to use it under Settings, Privacy and Security, Bluetooth. Make sure the model you picked in the app matches the model number on your scale. Step on the scale to wake it, keep your iPhone close and try again.
Close the maker's own app first, since a scale usually talks to one app at a time. If it still fails, choose Report connection problem in the app and keep the report ID it shows.
My scale isn't in the list
Choose My model is missing in the scale list and send the short report. It tells us which models people want next. See the supported scales for the current list.
Does it work while my iPhone is locked?
Often yes, depending on your scale. iOS decides when background apps get to run, so it can't be guaranteed every time. Opening SyncScale picks up a reading that was waiting.
Several people use the same scale
SyncScale saves readings as the phone owner's. Supported scales don't say who stood on them, so SyncScale can't tell people apart. Only set it up on the phone of the person whose readings should go to Health.
Apple Health
Readings don't show up in Apple Health
Open the Health app, tap your profile picture, then Apps, then SyncScale, and check that SyncScale may write weight and the other values you want. In SyncScale, Settings, Apple Health shows what's allowed and any reading waiting to be saved.
How do I remove readings?
Health stores your readings, so you review and delete them in the Health app. Turning off a permission or deleting SyncScale doesn't remove readings already saved there.
Trial and purchases
How do the trial and the purchase work?
The 7 day trial is free and never charges you. After it ends, new syncing pauses until you make the one-time purchase. There's no subscription.
Restoring a purchase on a new or reset iPhone
In SyncScale, open Settings, then Purchases, and choose Restore purchases. Use the same Apple Account you bought with. Restoring keeps the original trial date, so it can't start a new trial.
A purchase failed
Apple handles every payment, so we never see or change your purchase. If a purchase fails, choose Share purchase details in the app and attach the file when you write to us. It holds app and iOS versions and purchase steps, never your password or account. For refunds, go to reportaproblem.apple.com.
Write to the developer
Please don't send passwords or your health readings. Your scale model, iPhone model and iOS version are enough. If you sent a compatibility report, include its report ID: the report itself has no contact details, so this is the only way we can link it to you.
Include your scale model, iPhone model and iOS version, and the report ID if you have one. See how support email is handled in the privacy policy.
