Why the usual way fails
Phones sit on very different surfaces, from a wobbly café table to a solid desk or a soft hotel nightstand. The same small movement feels like nothing on one and like a grab on another. Many alarm apps start watching the moment you tap the button, so the movement of your own hand putting the phone down counts as a trigger. And most give you no way to see how sensitive they are until the alarm actually goes off in a quiet room, which is the worst moment to find out.
How MotionGuard helps
MotionGuard is built around that setup step. Before you trust it, a visible sensitivity test shows how the phone reacts to movement on the surface where it will sit. When you arm it, a settle delay gives you time to put the phone down and step back before monitoring starts. The free version uses Normal sensitivity, and Pro adds Low and High presets for surfaces that need a different setting. While it is armed, the monitoring state stays visible, and you can disarm it from the app or from the ongoing notification when you come back. After a trigger, the local history shows what set it off, which sensitivity you used and the coarse movement it saw, so you can adjust for next time.
“A visible sensitivity test lets you check how the phone reacts to movement before arming a full alarm.”
“Choose a settle delay, tap Arm, and let the phone settle.”
Step by step
- Put the phone where you will leave it, on the real table or nightstand.
- Run the sensitivity test and nudge the surface the way normal life would.
- Pick a settle delay long enough to put the phone down and step away.
- Tap Arm and let the phone settle.
- When you come back, disarm from the app or the notification.
- If it triggered, read the history entry and change the delay or sensitivity.
Tips
- Test on the exact surface you will use. A soft nightstand and a hard desk can react very differently to the same tap.
- If Normal is too jumpy on a shaky table, Pro adds a Low preset. High is there for places where only a firm grab should count.
- Leave the phone flat and away from the edge, so a passing bag is less likely to brush it.
- Remember that it is an alarm, not a lock. It makes noise when the phone moves, but it does not stop anyone from taking it.
Questions
Can I turn it off quickly when I come back?
Yes. You can disarm it from the app or from the ongoing notification.
Source: play.google.comAre Low and High sensitivity free?
No. The free core uses Normal sensitivity, and Pro adds Low and High.
Source: play.google.comDoes it record my phone's movement all the time?
No. Continuous raw accelerometer traces are not kept.
