### 1/5 — Needs to be updated!

*2018-08-20*

I loved this timer until I updated my iPad and now it will not work. I used this in my classroom everyday. Please update this app!

### 2/5 — Unnecessarily hard to use

*2017-08-22*

There are better timers available.

### 5/5 — Good!!

*2017-03-14, version 1.5*

Easy to use, adjust and reset.

### 1/5 — No sound

*2015-03-01, version 1.5*

Looked like a cool app but the noises don't work so useless to me

### 5/5 — Bang boom

*2014-04-11, version 1.5*

Very good! I like the very affectionate noises.
I use it nearly every day.

### 1/5 — ?

*2014-03-02*

The app doesn't go into landscape and when you open it it's upside down with the ipad. So, you have to flip the ipad. Not a problem unless you have a zagg keyboard like I do and then none of the plugs, speaker and charger fit the holes in the zagg case.

### 1/5 — Worst app

*2014-02-22, version 1.5*

No sound. Make you pay and then still no sound! No stars

### 1/5 — Nil sound

*2013-07-19, version 1.3*

Not happy! No sound!!!!!!! Why???? Please don't tell me to check the audio/ volume either. Refund!!!!!!!

### 1/5 — Garbage

*2013-03-06*

All ipad stands stand one way. This app is locked out upside down. It is completely useless unless you lay it flat on the table, and who uses an ipad that way? Total waste of time, uninstalled.

### 1/5 — No sound

*2013-02-04, version 1.3*

How do you get the sound to work?
Volume control is up full on the iPad so is there a settings switch to turn it on?
