### 5/5 — Perfect

*2021-01-16*

Great little app. Works as advertised. Need faster note? Divide by 2 each time from 16th notes to get 32nd & 64th notes. No ads is great!

### 5/5 — Does what it says

*2018-05-04*

I input the tempo and it tells me how to set the delay.  Although it may not go past 16th notes, you can just double the tempo to get shorter delay times.

### 2/5 — Rubbish😐👎🏽

*2017-10-03*

Ad supported can’t break down past 1/16 and no tap...exiting my iOS device after this review

### 5/5 — Good & Simple

*2013-09-27*

Does the job perfectly for me.

### 5/5 — Great tool!!

*2013-07-14*

After many years of struggling with tap tempo for my triplet delays, it hit us this morning: There has to be an app for that!   Indeed, and here it is and what a great app for just that.   Get the bpm from the drummer, punch it in and out comes a spot-on 1/8 dotted time to input into your fx.   My ocd side is rejoicing!
