Try these first
Most problems are fixed by one of these steps. Try them in order.
- Update the app. Open the App Store or Google Play and install any update.
- Close and reopen it. Swipe the app away from your recent apps, then open it again.
- Restart your phone. This clears most temporary glitches.
- Update your phone's software. Our apps work best on a recent iOS or Android version.
- Reinstall the app. Your purchase is safe. After reinstalling, tap Restore Purchases.
Check permissions
Some apps need access to a sensor to work. If you tapped "Don't Allow" earlier, turn it back on:
- iPhone: Settings, scroll down to the app, then switch on Camera, Microphone or Photos as needed.
- Android: Settings, Apps, choose the app, then Permissions.
Decibel Meter needs the microphone. TCG Vault and Protractor's camera mode need the camera. Colorzy needs access to the photos you choose.
Tips for specific apps
Stud Finder
Stud Finder uses your phone's magnetic sensor to find the metal screws and nails along each stud. Remove cases with magnets or MagSafe accessories, keep the phone flat against the wall and move it slowly.
Protractor
For edge measurements, take off thick or uneven cases so the phone sits flat. Hold it still for a moment before reading the angle.
Decibel Meter
Make sure nothing covers the microphone. Phone microphones are good for everyday checks, but they aren't a replacement for a certified sound level meter.
TCG Vault and Colorzy
Scanning cards and creating pages need an internet connection. Try again on Wi-Fi if it's slow.
