## Most critical reviews (5 lowest-rated)

### 3/5 — Good, small tweaks would make it great

*2018-09-21, version 1.3*

I suggest two small improvements:
1) The yellow and green numbers look too similar. I suggest making the yellow more orange. 
2) I don’t like that the clock turns back to red during the day. I wish I could set a time for it to switch from green to red in the evening. The red during the day is confusing to my toddler.

### 3/5 — Great

*2016-05-07, version 1.0*

Great in theory, I have an older iPod I use for white noise in my Son's room. Well because this app requires 7.0 and later I cannot download on the older iPod. I love that it doesn't interfere with the playing of the white noise on my iPhone 6 but it's worthless to me on my phone and not on my sons iPod. I think many people use older or used gadgets for their children. It's also great that the background is black and also allows the phone to sleep to diminish interference with sleep. Wish I could use it!

### 4/5 — Like the concept

*2018-07-19, version 1.3*

Really like the concept, but was hoping to use it basically in reverse, as more of ‘time is up’ timer, going from green to red, which it currently isn’t set up to do.

### 4/5 — Works Great

*2014-09-12, version 1.0*

This is pretty much exactly what I was looking for. Only thing that would make it better is some sort of optional way to indicate passage of time. Could be gradual color change or maybe some other clock element like a rectangle that fills in gradually.

### 5/5 — Good response from developer

*2018-01-01, version 1.2*

I posted an issue with app not working on my iPad. Developer responded immediately that an Apple update had caused the dysfunction and he was working to correct (and did so). App working well now.
