BeatMirror uses your device's built-in microphone to detect musical tempo in real-time. Just tap start and a 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 songs in real-time!
TESTIMONIALS:
"BeatMirror 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 BeatMirror 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 BeatMirror, 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 BeatMirror just makes sense." - Laura Barnes of MI-PRO (mi-pro.co.uk)
FEATURES:
Good music needs good rhythm. But learning to stay on beat—learning to groove—isn't always easy. Build your inner metronome with BeatMirror and catch yourself when you're speeding up or slowing down. Here’s what BeatMirror has to offer:
- Wide tempo range. Tempo detection between 35 bpm and 220 bpm.

- Real-time, scrollable graph. Displays current tempo and tempo history in real-time.
- Zoom features. Choose tight, loose, or full zoom—or double-tap the graph for easy toggling.
- Easy sharing. Share your tempo graph with a tap.
- Easy-to-read interface. Optimized for various light environments, such as stages and practice spaces.

TIPS FOR BEST PERFORMANCE:
- Avoid handling your device during tempo measurement.
- Be mindful of competing noise near the device's microphone (e.g., conversation, typing).
NOTES ON USAGE:
- Recorded music. To detect the tempo of recorded music using BeatMirror, follow these steps:
1) Play a song from your favorite music player app using the device speaker (i.e., unplug your headphones). Or, play the song from a different device altogether.
2) Open BeatMirror and start tempo detection, adjusting the tempo range if needed.
3) The song's precise tempo will then be displayed in real-time.

I’m a professional drummer/teacher who was using and endorsing the BeatNik Rhythmic Analyzer from Onboard Research since 2008. When the company folded in December of 2017, I was dreading the day both my units would malfunction. It used to be a simple matter of me sending them in for a free repair under their lifetime warranty. Now I needed an alternative. I did some research and stumbled upon the Beat Mirror. It took a little getting used to but is far more simple and intuitive to operate and it doesn’t have the risk of a sensor going bad. The price point is reasonable and having the functionality on both phone and iPad make it super convenient. The developer is very responsive and quick to answer questions and offer solutions. All in all I’m very pleased with Beat Mirror and know my students will be as well!
New version makes this superior
Fiddlocity
Gigging musician here. Just started using it, but I’d say this version makes the Beat Mirror app superior to other tempo detectors that I and bandmates have previously bought and used. Seems to be very accurate. Displays tempo and draws a line in real time. Two different zoom settings. Does fine with 3/4 time also when some others do not. Target tempo is a standout feature, with an illuminated strip showing when you’re staying close. Haven’t used the range option, because for our use it’s way too broad, even though you can slide the range up and down. Wish one could further customize the range to better zoom in on the tempo graph. But overall, really like it so far.
Great for keeping you and the band honest.

I like to use this app during band practice. I set the bpm for the song we’re about to play and keep a casual eye on it to make sure we’re not getting carried away. I have a pretty fat pocket, but that doesn’t mean the other guys don’t want to run off with the tempo. So I can glance over periodically and check that we’re still within 5 or soBPM of where we should be. I can also check the graph after the fact and see where we wobble a bit and where we lock in, etc. Good tool. I haven’t used it in a performance, but probably will.
Incredible App with SP404MKII ETC!

After years of tapping to determine BPM using hardware and apps, I never understood why it seemed so difficult to find the BPM of a sample or song. My Korg KP3 did a good job, but now that hardware music devices have audio and MIDI over USB-C, this app is a must-have for me. I've never written a review of an app before, but I tried several other BPM apps which still required me to tap for BPM or only showed popular music BPM.This app is perfect for use with new samplers and any app where your loop needs to be perfect. Unless you're only producing dance music that hovers around 120 BPM or whatever and you don’t change the original beat in samples, you need a simple app like this. I use old vintage analog live 'standards' samples or obscure things for sound design, and while it will fluctuate, the app includes an option to use a different algorithm, each of which works slightly differently. It's fun to watch the BPM needle move along and draw out the beat as a fluctuating line on a heart monitor.I just got this the other day, and I was amazed when I opened the app on my iPad Pro M2, plugged in my SP404 Mk2 to a daisy-chained third hub with USB-C, and instantly saw the BPM of everything I was doing while the music was playing via monitors or headphones! I didn’t believe it was working, so I tried different samples, and it matched right away.It may need more features to thrill others, but it’s great as it is. I have a couple of requests at the end.I've been quickly fixing samples that I thought were good by ear, but the app synced them perfectly. I'm on a steep learning curve with two new hardware samplers, every decent iPad app (2000+), and I just got the SP404 and recently a Polyend tracker, plus the new Zoom R4 4-track recorder and the new Minifreak I got last year. I am overwhelmed, but I'm an artist with ADHD who is also obsessed with sound design since I first heard Kraftwerk on reel-to-reel in high school!
We've got a big update for you today. It's been months in the making, and today we are very happy to announce BeatMirror's brand new Range mode!
It's the same BeatMirror you know and love, but now you have the option to set a nice big tempo range (instead of a target tempo) and start detecting tempo right away. The new Range mode also has a special triplet option for high accuracy in triplet-time. (You'll get a mini-walkthrough when you update the app.) Finally, we've added the ability to listen to whatever you like in your headphones during tempo detection (music from other apps, metronomes, etc.).
I hope you like the new update. And as always, I'd love to hear any feedback you have. Just tap the envelope icon in BeatMirror to get in touch and I'll get back to you ASAP. -Alex
