Keep Time

I love this metronome for silently keeping time. I would give the app 5 stars if the number of colors in the rainbow mode matched the number of beats per measure so that the first beat was always a designated color. I’m able to keep time to the color change while reading music, but I have difficulty noting the position of the color bands while reading music.

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!

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.
