Beat Mirror uses your device's built-in microphone to detect musical tempo while you play your instrument or your favorite tracks! Set a target tempo with the special tap-for-tempo feature and then start the music. A real-time graph of your tempo will appear right away, allowing you to scroll through your tempo history and see trends. Perfect for musicians looking to build their internal rhythm, or to see the tempo of their favorite tracks in real-time!
"Beat Mirror truly is simplicity at its finest. That quality is missing from most apps who try to cram too many features into one app thus making it difficult to use and many times buggy. We feel like your app is VERY good. We're reviewing Beat Mirror and it will be a part of the next show. It's got nothing but thumbs up!" - Phil Smith of "Drummer's Weekly Groovecast" (podcast)
"When I first heard about Beat Mirror, I was kind of skeptical but after trying it out for weeks now and playing with it everyday, I'm mindblown. Alex really wanted to put a focus on helping drummers improve their internal clock and I really think he's done so." - Richard Ducat of "Drummers I Like" (podcast)
"Overall, this app is so quick and simple to use, there’s not really an excuse as to why you wouldn’t use it during practice sessions, just to see how you’re improving. If you’re a drummer, having an app on your phone or tablet like Beat Mirror just makes sense." - Laura Barnes of MI-PRO (mi-pro.co.uk)

Ratings and Reviews
Great tool for improving tempo
As an adult drum student, I'm always striving to improve my groove and my stability of tempo. Beat Mirror does a great job of tracking my tempo, giving me a realtime graph of my played tempo. What is remarkable is that whether I play 16ths, or triplets (12ths), or quintuplets (20ths?) it follows without a hiccup.
The developers are wonderful, very friendly and responsive. Not that I had any issues, I just emailed a suggestion for a future version, and they were very receptive and genuinely excited about what they are doing!!
Very helpful tool!
When songwriting, I often have trouble figuring out the tempo I’m looking for. This app helps by recognizing the tempo in real-time while I’m jamming.
The worst app in eleven years
The fact that Apple sells this tells it all.
Never has $5 & tax been so savagely wasted on an AWFUL app.
Hi Ian, Thanks for reviewing the app, though between this and your emails, I'm not sure I understand the issue you're experiencing. In any case, I'm certainly happy to help with support anytime. Just get in touch at alex[at]tenkettles[dot]com. Best, Alex
