How can we help?

Email support@stax-apps.com and a person will answer. Tell us your phone model and whether you are on iPhone or Android. Never send us your password; we will never ask for it.

The readings seem too high or too low

Phone microphones are not calibrated instruments, and each model is different. Open the tune menu on the meter and set a calibration offset by comparing against a reference meter in a steady sound. Hold the phone the same way each time, away from your body, with no case covering the microphone. Also check the weighting: dBA (the default) reads lower than dB SPL on bass-heavy sounds, and that is expected.

The meter shows nothing or stays at zero

Check that dB Meter has microphone permission in your phone's settings. If another app is using the microphone, or a phone call is active, the meter cannot read it until that ends.

Subscribing, the free trial, and cancelling

The first 3 days are free. The store charges you on day 3 unless you cancel before then. To cancel, use your phone's subscription settings: on iPhone, Settings › your name › Subscriptions; on Android, Play Store › profile › Payments & subscriptions. You keep access until the end of the period you paid for. Deleting the app does not cancel a subscription.

New phone, and the app wants me to subscribe again

Tap Restore Purchases on the paywall while signed into the same Apple ID or Google account that bought the subscription. Your subscription comes back without a new charge. If you also had a dB Meter account, sign in instead, and your readings come back too.

Do I need an account?

No. You can subscribe and use everything without one. An account is only for backing up readings and seeing them on another phone. Create one in Settings whenever you like, or never.

I switched between iPhone and Android

Store purchases do not cross platforms on their own. If you created a dB Meter account before switching, sign in on the new phone and your subscription and readings follow. If you had no account, the subscription stays with the store you bought it from.

Deleting readings or my account

Swipe or long-press a reading to delete it. To delete your account, see Delete account.
