## Description

Alarm is a self-defence/emergency alarm application with a rapid-movement and free-fall detector.  You can also touch the screen to give a warning.  

Not only a red screen blinking but also an alarm sound and a flash light are synchronized if the device has such functionalities. 

The Apple Watch app also blinks but it's limited for a few time only to save the battery.

## Review summary

Most reviews view Alarm Free as impractical for real self-defense. The alarm is frequently too quiet, and it often fails when the phone is asleep or locked, delaying activation. Its functionality is very basic, providing a blink and a sound rather than a proven deterrent. A few users like the simple, one-tap alert or enjoy it as a harmless novelty, but the majority consider it ineffective and not worth relying on in danger.

### Pros

- One-tap emergency alert concept (easy to trigger to signal for help or deter an attacker).
- Simple, easy-to-understand alert idea that some users appreciate as a quick signaling method.
- Some users enjoy the app as a harmless novelty or prank, appreciating the lighthearted use.

### Cons

- Alarm is often not loud enough to be effective in real danger.
- Does not work well when the phone is sleeping or locked, requiring unlocking and taking time to activate.
- Extremely basic functionality (blink light + sound) with little real deterrent value against attackers.
- Overall sentiment is largely negative, with many calling it useless or a waste of time.
