Key Features
- Explicitly arm a phone motion alarm and immediately disarm from the app or ongoing notification
- Use Normal sensitivity, settle-delay controls, sensitivity testing, and local trigger history in the free core
- Unlock Low and High sensitivity presets with MotionGuard Pro
- Add Pro charger-removal monitoring when the phone is connected to power at arm time
- Review what triggered an alarm without retaining a continuous raw accelerometer trace
- Mirror the phone status on a paired Wear OS watch and open MotionGuard from the read-only status Tile
- Receive best-effort Pro trigger alerts on the paired watch when connectivity and notification state allow
- Choose an explicitly requested rewarded ad for an 8-hour Advanced Guard Pass after server verification, or make a one-time lifetime Pro purchase; there is no subscription
- No MotionGuard account or developer-operated cloud backend is required; core motion monitoring is local, while optional purchases and rewarded ads use Google Play, RevenueCat, Google AdMob, and Google UMP
- Focused alerting utility only: MotionGuard does not prevent theft, track a device, provide emergency monitoring, or guarantee remote alerts
Frequently Asked Questions
Is MotionGuard a theft-prevention or tracking service?
No. MotionGuard is a user-armed local alerting utility. It does not prevent theft, track a device, provide emergency monitoring, or guarantee that a remote alert will be delivered.
Does MotionGuard show ads?
MotionGuard has no banner, forced interstitial, or app-open ads. A rewarded ad is requested only when you explicitly choose Watch an ad for temporary Pro access and Google UMP reports that ads may be requested. Ads are not shown while the phone is arming, armed, alarming, or disarming. The optional lifetime Pro purchase avoids rewarded ads entirely.
Does MotionGuard use my location?
MotionGuard does not request Android location permission. If you explicitly request a rewarded ad, Google AdMob may process an IP address and infer approximate location for ad delivery, measurement, security, and fraud prevention according to applicable consent choices.
Does the Wear OS app replace the phone?
No. The phone owns the authoritative armed session. The paired watch mirrors status, provides a read-only Tile, and can receive best-effort Pro alerts when connectivity, notification state, and entitlement allow.
Does MotionGuard require an account or developer cloud?
No. MotionGuard has no account system or developer-operated cloud backend. Core monitoring runs locally. Google Play and RevenueCat handle optional purchase and entitlement flows, while optional rewarded access uses Google AdMob and Google UMP.
Is MotionGuard Pro a subscription?
No. MotionGuard offers a one-time Lifetime Pro purchase. Users can also explicitly request a rewarded ad for temporary Pro access.
