The short answer
You don't need to hunt for a Mouse Timer APK. The official Android app is free on Google Play, where it installs in one tap and updates automatically. iPhone and iPad users get it from the App Store. Both listings are published by LITALICO Inc.
APK files are Android installation packages. Downloading them from mirror sites skips Google Play's checks and means you won't receive updates — with no benefit, because the real app is already free and ad-free.
Install on Android (step by step)
- Open the Mouse Timer page on Google Play (our download buttons go there in the same tab).
- Check that the developer shown under the title is LITALICO Inc.
- Tap Install. Google Play tells you if your device isn't compatible.
- Open the app, choose a time, and the countdown begins.
- If you want alerts while using other apps, allow notifications when asked.
The package name of the official app is jp.co.litalico.mousetimer1. If you ever see a file or listing with a different developer, it's not the official app.
Install on iPhone, iPad or Mac
- Open the Mouse Timer App Store listing.
- Confirm the seller is LITALICO Inc.
- Tap Get, then confirm with Face ID, Touch ID or your password.
- On a Mac with an Apple M1 chip or later (macOS 11+), search the Mac App Store; the iPad version is listed there.
The iOS download is about 61.8 MB and requires iOS or iPadOS 13 or later.
Why avoid APK mirror and “MOD” sites?
- Tampered files: repackaged APKs can contain adware or other unwanted code.
- No automatic updates: side-loaded copies don't update through Google Play, so you miss bug fixes.
- Security warnings: installing them often requires allowing “unknown sources”. We don't recommend turning off security protections on your device.
- Nothing to unlock: “MOD” versions promise premium features, but Mouse Timer has no paywall to remove.

No Google Play on your device?
Some tablets and Chromebooks don't have Google Play, or it's disabled by a school administrator. Rather than side-loading an APK, use a browser-based timer. Our homepage timer runs in any modern browser, needs no install, and can be switched to a big-screen view for classrooms. If the device is managed by a school, ask the administrator to approve the app through the official store.
Keeping the app updated
Store-installed apps update automatically when auto-update is on. On Android, open Google Play, tap your profile picture, then Manage apps & device to see pending updates. On iPhone and iPad, updates appear in the App Store under your account. Updates to Mouse Timer have been occasional — it's a small, focused app — but they include useful fixes such as keeping the timer state and preventing screen dimming.
What is an APK, anyway?
APK stands for Android Package — the file format Android uses to install apps. Every app you install from Google Play is delivered as an APK (or a set of split packages) behind the scenes, so you never need to handle the file yourself. When people search for a “Mouse Timer APK”, they usually want one of three things: a way to install on a device without Google Play, an older version, or a “free” copy of a paid app. The last doesn't apply here, because Mouse Timer is already free.
What the app needs on your device
Mouse Timer is a simple utility. It doesn't need an account, and the App Store privacy label said “Data Not Collected” when we checked. On Android, you may be asked to allow notifications so the app can alert you when time is up while you use other apps. If any copy of “Mouse Timer” asks for unusual permissions — contacts, location, SMS — treat it as a red flag that you haven't got the official app.
Tips for parents installing on a child's device
- Use family controls (Google Family Link or Apple Screen Time) so new installs need your approval.
- Install the app yourself and set up the reduced time choices before handing the device over.
- Place the icon on the home screen so your child can find it without browsing the store.
- Turn on notifications if your child will use the timer while doing something else on the device.
Uninstalling or reinstalling
To remove the app, long-press its icon and choose Uninstall (Android) or Remove App (iOS). Reinstalling is free from the same store page. Since the app doesn't use accounts, there's nothing to sign back into — just choose a time and start.
