*2016-04-18, version 1.2*

I just downloaded this app today, tried to open it for the first time but it crashed. Then I tried re-opening it for another time, then another, and for the fourth time, it still crashed. Please fix app, I would like to try it out. Thanks!

### 5/5 — Lovers gonna love

*2015-02-22*

Have had this cute app for over 4 years. I use as the rear light on my bike and as a warning light for cars when I go running. I would get it again, any day.

### 1/5 — Doesn't scare a cat

*2013-12-26, version 1.2*

So, I downloaded this thinking I'd use it as an irritation if (when) my cat jumps on the counter while cooking; and then maybe have it ready if I got into a sticky situation and wanted a deterrent. Nope, already uninstalled. It didn't even bother my cat.

### 4/5 — Bien

*2013-07-13*
