Minimal Night Check

Minimal Night Check shows you what apps did on your phone while you slept. Open it in the morning and one color tells you if anything looked wrong. 🌙 How it works 1. Allow "Usage access" once. 2. Each morning, open the app. 3. White means all good. Light pink means worth a look. Red means please check. 4. Tap an app to see what happened, why it matters and what to do next. What it checks During your sleep hours (12–6 AM by default, or 1–7 AM or 11 PM–5 AM): - Apps that started while your screen was off - Apps that used much more data than on other nights - Apps not from an app store that went online or ran in the background It also checks which apps have special access to your phone: - Accessibility, notification access, device admin, keyboard, default SMS app, display over other apps, usage access and installing apps You see apps that got new access, and apps not from an app store that hold this access. The Access screen also shows if you have added certificates or turned on USB debugging. Simple rules 🚦 The app does not guess. It uses rules anyone can check: - Red: an app not from an app store woke up, went online or holds special access - Light pink: something unusual, such as an app waking up with the screen off or using much more data than usual - White: nothing unusual If you installed an app yourself, tap "I installed it". The app remembers it with the app's signing certificate, so a different app with the same name is not trusted. You can reset this in Settings. What it does not do - It does not scan files for viruses. - It does not see what apps send or where they send it. It sees how much data each app used. - It does not block, stop or remove apps. "App info" opens Android settings, where you decide. - It checks only when you open it. It does not run in the background. - Data use is counted by Android in about one-hour blocks. Offline and private The app does not have internet access. Nothing leaves your phone. There is no account, and no ads, analytics or tracking. The list of your apps and their activity stays in memory only. The app saves only two small encrypted lists on your phone: which apps had special access (to spot new access), and the apps you marked "I installed it". They are not backed up and are removed when you uninstall the app. Permissions - Usage access: to read which apps started and how much data they used. You turn it on in Android settings. - Query all packages: to see your installed apps, where they came from and their special access. Design Short English words, few icons. Light and dark themes. Support ☕ All features are free. If you would like to support development, there are three optional in-app items (Coffee, Lunch and Dinner-sized Support). They do not unlock anything. A small support message may appear on the 10th day of use, then every 100th day, and stops once you have supported.
