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)

Delivering the Beat w Instant Feedback using Beat Mirror
A metronome is fine when I need to RECEIVE a steady mechanical beat but I needed an app which I can DELIVER my internal beat to and receive instant feedback of how accurately (or inaccurately) I perform on drums (or guitars).
Beat Mirror is exactly as advertised! I’m now able to truly find out how steady my drum meter is by opening this app, setting my Target Speed in BPM, clicking play, follow my optional Count In, and start drumming! This app is extremely simplistic to use with unlimited upside and worth every penny of the bargain price tag. I’ve practiced with it for over 7 real time hours since purchasing it yesterday so it’s already paid for itself many times over.
As far as Customer Care, I reached out to the Designer with a few enhancement ideas/suggestions yesterday and he responded to me immediately, that’s how you take care of customers!
I highly recommend Beat Mirror to any level drummer or musician who wants instant feedback when DELIVERING the beat whether in a practice session, a live jam, or for on-stage performances.
Practicing with a metronome is fine when you want a mechanical click to do all of the difficult work for you, keep steady time. However, if you truly want to become a steady drummer and develop your internal clock, Beat Mirror is what you need!
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!!
I only record drums now but retired I have plenty time. With iPad mounted by kit & QSC mixer I can see how much drift I have. It is actually less than I thought. It’s easy, fast & accurate in real time. Wish I had it 40 years ago as a kid! Highly recommended~!!!
With Family Sharing set up, up to six family members can use this app.
