Please raise tempo limit

This is an excellent app. I am a fan of Cleartune as well. I got this Clockwork app because of the feature that enables you to adjust the length of subdivisions. While learning a movement of Bartok Quartet No. 5 which was in 9/8 that had subdivisions of 4+2+3, this app was terrific except that I needed a tempo of 414 and the limit on the app is 300. Please raise the tempo limit to 420 and you will increase your number of users. I believe that Tempo by Frozen Ape has a tempo limit of 400. It lacks the adjustable subdivision feature which is unique to Clockwork.

It's a powerful metronome app that is super easy to use and intuitive to figure out. When you want a basic click to keep time, it doesn't get in the way. But when you want more control, it's ready for you! I used it to easily program complex tempo and meter changes for Bartok - something no physical metronome has ever been able to do, and a task which is cumbersome on other metronome apps. It seems like there might be a bug that makes editing click tracks very difficult after the initial creation. Overall, however, well worth the money!

...I just wish the accent didn't keep turning back on every time I make a change... But this is a small gripe!

Nicely written App!

LIke it's companion app ClearTune, this is a well thought out, well written app. I've tried a few others but this one is straightforward, and intuitive. The user interface is clear and easy to use. I never use emphasis because as a percussionist, play works with complex meters. I would be great if the app would save the current setup as a default, otherwise, this is my favorite and only metronome. It's loud enough and the visual feedback is helpful as well. I haven't tried the click track editor yet but what I really want is a simple, well implemented app, which this clearly is.

PS I'm clearly NOT "dissapointed" and don't understand how this designation got assigned.
