### 4/5 — It's good....

*2014-08-04*

But it doesn't feel as responsive as it used to. They keys don't feel as if they are responding to your touch. Apart from that if you work in radio - it's very handy!

### 5/5 — Essential radio presenter tool

*2014-07-12*

Genius. You guys gotta send a link to all radio presenters. Or certainly add it in the description. This is amazing. Worked perfectly. Thank you.

### 4/5 — I use it all the time

*2013-01-15*

If an ad break starts at 56:40 it would be nice to start the calculation from there. 5 stars when that is added :)

### 5/5 — Works well - very helpful.

*2012-06-07*

As a radio host, I need to time all segments of the hour down to the second.  I find Back Timer very helpful.

Nothing. Apple is making me create a new version because they can't conceive of the idea that software doesn't need to be updated. But I guess that we need to take marching orders from the company that the forcing liquid glass on us. That's Apple for making me waste an afternoon doing nothing to this app.
