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. - Fast. Detects tempo quickly and accurately. - Flexible.

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. - Tempo keyboard. A special tempo keyboard (with tap pad) lets you set a target tempo easily and intuitively. - Visual feedback. If you drift from your target tempo, BeatMirror shows a red (slow down!), blue (speed up!), or green (perfect!) indicator. - Custom count-in. BeatMirror gives you an optional count-in before you start playing. - Versatile. Perfect for solo practice, band rehearsals, recorded music, and you can even use it at concerts! - Triplet mode. Boost accuracy in triplet-time with the new triplet mode. - Tutorial. An in-app tutorial gets you up and running in a flash. 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.
