Nice but lacks basic steady rhythm.

It's a very simple to use app with nice features. Nothing fancy, just exactly what you need. Swing beat, increasing or decreasing tempo are nice and humanize feature is cool. But there seem to be a bug so even if I put humanize to off, the metronome doesn't play a straight rhythm. It's still usable but really annoying. If that was fixed I'd put a 5 star rating.

Great but for a couple of flaws

Would be great but for one giant flaw. While the app is running, if you accidentally swipe across the screen, for example when moving the phone, it changes the BPM to match what it thinks you tapped, with random results. I have several times started recording something and then noticed that the app's tempo was way off from what I had set. This could be easily fixed by adding a 'lock tempo' option but right now there's now way to lock in the BPM. This happens to me pretty much whenever I use the app. Also a minor flaw: the font used to tell you what BPM it's been set to is very very small. But this is the one piece of information a user will need to see without having to get up close to the phone!

Except for one little request... Can you add a "silent" sound for the beat (for when I forget to mute phone?) This app is awesome for psychoeducational testing when counting seconds must be precise. I can see the colors out of the corner of my eye. Perfect! Best visual metronome out there. Thanks!
