A fantastic app; the best metronome available.

This is by far the best metronome available in the app store; it’s versatile, endlessly customizable, and incredibly user-friendly. What’s more, the dev seems to be wonderfully responsive.

I do have a wish: I wish this metronome was configured to work as an AUV3 extension. No metronomes seem to do this; but it seems like it would be incredibly useful to be able to chain a metronome into a full sound production setup in an app like AUM or Audiobus. When I’m practicing or recording myself playing piano, it’s usually inside AUM; and while it works to have Dr Betotte open in a floating tab (it’s great that it has that functionality!) it is a little glitchy that way (has to be isolated every time you open it by sliding over, and sometimes crashes) and would work better if it were just directly chained into AUM as a AUV3 (or even IAA) sound module.

No other metronome app seems to do this, so it’s not something I’m annoyed about. Dr Betotte works so great without this feature that I’ll be happy with it and use it anyway. But it would be a cool way to distinguish the app, since there seems to be a vast ocean of relatively basic metronomes.

Still, this is the best one. It’s very good.

Only works with ringer on and does not work in background :(

I have been using this met for a couple years and it’s been wonderful up until recently- now it only works when my ringer is on and will not play if I close out of the app. I tried restarting my phone and uninstalling/reinstalling the app but I’m still having the same issue.

This app needs a users manual

I bought it, but I’m not going to use it. I can tell you that it is a well thought out, versatile, and feature rich, app. Here is my example: 2/4 time, on beat #1 play four 16th notes, the first two notes are assigned sound A. The second two are assigned sound B. For beat #2 use sounds A and B to play two 8th notes. This is the kind of metronome i use to practice drum sticking exercises. How can this be done? Maybe I can do it with the sequencer feature, but that is the main problem. The developer provides a sequencer, but no documentation on how to use it. It is not intuitive enough for the uninitiated. The built in help is lame; the online help does not exist. Ill go back to using Metronomics until there is better support for this app. Ill give it 5 stars when some better documentation shows up

Developer Response ,

Hi, Thank you so much for downloading Dr.Betotte TC and apologize for not providing enough documentation. I created a quick instruction to make sequence that you mentioned here. Please visit ““. If you have any question, please feel free to contact me at
