### 1/5 — A 5 second extremely repetitive and annoying loop. Waste of Money

*2018-07-09*

I used this to focus this morning and it is the first time I have really implemented using it for more than 5 minutes since I bought the app. I found myself getting extremely irritated and annoyed by the constant sound repeating. When I skipped to the next track and heard it was a similar 5 second loop as well. I just thought what a total waste of money. I wish I had never purchased this app. I will stick with one of my premium focus services instead of using this. It actually ensured I lost my concentration. The fact it doesn’t skip into another track means I have to get irritated and then skip a track, not exactly what I want to focus on study and other things I need to do.

**Developer response:** Thank you for your honest review, I am sorry it did not fit your needs. I have recently added new music patterns, please feel free to check them out.

### 3/5 — Are the Binural beats for sleep? If so Delta or what frequency?

*2019-09-25, version 1.3*

Are the Binural beats for sleep? If so Delta or what frequency?

### 4/5 — It works great!

*2021-11-17, version 1.4.4*

A nice simple app that helps me focus or fall asleep!   

Suggestion:  add track numbers so I can go back to my favorites.

### 4/5 — Really like it!

*2021-04-06, version 1.4.2*

This is very nice and simple to use, and it is very helpful. It would be good to add a sound name or track number so you can reference the ones that work best and go back to it.

### 5/5 — This is great.

*2022-04-05*

I use this for my deep work sessions and it’s exactly what I need. Easy to get started and I love the timer.
