Speedbreaker

Make the next tap intentional.

Speedbreaker adds a breathing pause before the Android apps you choose. Take a moment, then continue, leave, or open somewhere else. Optional check-ins bring that same pause back during continuous use.

Android 8.0 or newer. Installed from an APK; not currently on Google Play, F-Droid, or iOS.

The current version is 1.0.7. Recent versions added a total of the time you have breathed, in-app updates for the GitHub APK, a guided two-step setup, breaths that no longer need Phone permission, a separate Settings page, and counts of what you chose after each breath. See the latest release and the changelog.

A little room to choose

• Choose your own apps. Nothing is selected for you.
• Take a breath. Twelve seconds by default, adjustable from 8 to 60 seconds.
• Decide what comes next. Continue in the app, Leave for your home screen, or choose from up to four optional detour apps, with their own icons.
• Check in again. By default, another breath follows ten minutes of continuous use. Change the interval or turn check-ins off for each app.
• Set your hours. Stay active all day or choose a weekly schedule, with separate schedules for individual apps when needed.

There are no streaks, usage scores, or daily screen-time budgets. Speedbreaker works locally, without an account, ads, analytics, or cloud sync.

From 1.0.4 the GitHub APK updates itself when you ask: Check for updates in Settings (the gear on Home; at the foot of Home through 1.0.6) asks GitHub for a newer release, and Update downloads it, checks it, and hands it to Android's installer. An optional daily check is off until you turn it on there.

A look inside

Take a breath	Choose what comes next	Make it yours

Screens rendered from the app's UI with example settings. App icons appear as monograms here; installed apps show their own icons on a phone. You choose your own apps and detours.

Install and get started

1. Open the latest GitHub release and download the .apk from a release's Assets, rather than a source archive.
2. Open it on your phone. If prompted, allow your browser or file manager to install this APK, then follow Android's installer.
3. Open Speedbreaker, tap Continue, read the Accessibility disclosure, and tap I understand — continue. Home then lists two steps.
4. Tap Turn on in Accessibility and enable Speedbreaker.
5. Speedbreaker opens again by itself; if it does not, press Back. Tap Choose apps, then open a chosen app to try it.
6. Optional: open Settings (the gear on Home) and, under Reliability, tap Phone permission and allow it, so a breath also steps aside for a call that rings without a ringtone (silent, vibrate or Do Not Disturb).

If Android says the Accessibility setting is restricted, open Speedbreaker's App info → ⋮ → Allow restricted settings, confirm your identity, and return to Accessibility. Menu names vary by phone. Keep Play Protect enabled.

Allow notifications (Settings → Reliability → Notifications) to use the fifteen-minute Pause option. On Samsung, check Settings → Reliability → Battery and background for background-operation guidance. Through 1.0.6 these rows sit on Home itself. See the setup and troubleshooting guide for details.

Verify the APK

Each release lists a .apk.sha256 file beside the APK. Before installing, run sha256sum -c Speedbreaker-X.Y.Z.apk.sha256 in the download folder (or compare sha256sum Speedbreaker-X.Y.Z.apk with the published value). To check the signer, run apksigner verify --print-certs Speedbreaker-X.Y.Z.apk from the Android SDK build-tools. The certificate SHA-256 should be fe3fcd3e893fe89d97aba6e25b429e9140455846423c2b42c44bfb4fcc320272 for Android 9+, or 8063da543d9e65ccf8ec4267e0710439f67af51d4990720f0ae36bef236a98ca for the original Android 8 signer. A checksum confirms the file matches; it is not an audit.

Know how a breath behaves

The first eight seconds intentionally hold the breathing screen. Home, Back, and Recents cannot dismiss it during that time. At eight seconds, Leave, configured detours, and Pause become available; Continue waits until the full breath finishes. Ordinary navigation can leave after eight seconds.

Each chosen app gets two fifteen-minute pauses per local day. Active pauses on the home screen and the pause notification both offer End now; the in-app control remains available if the notification is dismissed. After Continue, returning within ten seconds resumes the session; a longer absence starts a new opening breath. Visible apps in split-screen and picture-in-picture count toward check-ins.

The app yields to Android-reported calls, communication audio, the dialer, the lock screen, screen-off, and Android Settings. Calling apps that do not report their calls to Android may not be detected while ringing. One Hand Operation+ edge gestures are unavailable while the overlay is visible; use Leave, a detour, or ordinary navigation once choices unlock. You can turn Speedbreaker off in Android Accessibility settings.
