Answers to common questions about Hakari, supported scales, Apple Health and purchases.
Which scales are supported?
Hakari is tested with the eufy Smart Scale P2 Pro and supports other eufy Smart Scales that use the same protocol (P2, P3, C1, P1, A1, C20 and more). If your scale isn't recognized, open Settings › Bluetooth Diagnostics, step on the scale, then export the capture and email it to us.
Do I need to keep the app open?
For the most reliable recording, open Hakari before stepping on. Scales that support it are also received while your iPhone is locked or the app is in the background.
Is my data uploaded anywhere?
No. Hakari has no account and no servers. Readings are stored on your iPhone and, if you allow it, in Apple Health.
Why is a reading marked “To Review”?
A reading far from your recent trend is held so someone else on the same scale doesn't end up in your history. Tap “It's Me” to keep it or “Not Me” to discard it.
Are body metrics accurate?
BMI, healthy weight range and BMR are calculated with published formulas and are estimates. Talk to your doctor before making health decisions.
Restoring purchases
Open Hakari › Settings › Hakari Pro and tap Restore Purchases while signed in with the same Apple Account.
