In the app, tap Settings → Send feedback: it opens an email to me with the app version already added. Or write to superator2018@gmail.com, and please include the app version (Settings → About & support the developer), your phone model and what happened. I read every message.
Yes. The everyday tools are free, complete and without ads. Multitool Pro is a one-time purchase, not a subscription. It unlocks Sensor dashboard, GPS info, Network info and Dev utilities, and it supports the app’s development.
Sign in to the store with the same Google account or Apple ID you used to buy it, then tap Settings → Restore purchases. On iPhone, Pro is also shared with your Family Sharing group.
Purchases stay within one store: Pro bought on Android doesn’t carry over to an iPhone, and the other way round.
No. Everything works offline except the public IP lookup and ping to addresses on the internet (ping to devices on your own network works without it), buying or restoring Pro, sending feedback, and opening links: from scanned codes, and the Help and Privacy pages.
Your phone doesn’t have the sensor that tool needs, for example a magnetometer for the compass or a barometer for air pressure. The app can’t replace missing hardware.
Open the tool again and tap its Allow button. If the app shows Open system settings instead, tap it and allow the permission there. The app asks for a permission only when you use a feature that needs it, and everything else keeps working.
Tap Calibrate in the compass and move the phone slowly in a figure 8. Keep away from metal, magnets and phone cases with magnets.
Both can be calibrated. In the ruler, tap Calibrate, choose a bank card, a coin or a ruler, and resize the outline until it matches. In the level, put the phone on a surface you know is level and tap Calibrate.
No. Phone microphones aren’t calibrated measuring devices, so readings are approximate. They are good for comparing places and noises, not for official measurements.
Allow notifications when the timer asks for them. On Android, also tap Allow alarms when asked, so the timer rings on time while the phone is idle. Some phones stop apps in the background to save battery: if the timer still doesn’t ring, turn off battery optimization for Multitool in the system settings.
No accounts, no ads and no tracking. Crash reports help me fix errors and can be turned off in Settings → Send crash reports. Pro purchases are checked by RevenueCat, and on Android the QR scanner reads codes with Google’s ML Kit, which sends Google technical data. Details are in the privacy policy.
Settings → Language. The app is available in English, Ukrainian and Russian.
