Don’t know how hot but uncomfortably warm. Didn’t check battery drain. ### 5/5 — Essential Tool! *2025-04-26, version 3.0.0* BeatMirror should be famous. There are two tools EVERY musician who wants to improve their tempo needs: a metronome and BeatMirror. A metronome trains you to (re)sync with an external reference. BeatMirror shows you what your internal tempo is and how (un)stable it is. The app interprets tempo accuately even when there are complex rhythms. It’s rock solid and works well in a practice room, rehearsal, and on stage! I highly recommend it!!! ### 2/5 — Doesn’t work unless you set target tempo. *2024-10-18, version 2.6.0* I just wanted an app to tell me the bpm. Paid 5 bucks and immediately deleted. ### 5/5 — Not ideal for DJs *2024-06-21* Hi Alex, this is a super beautiful you provide. As a Vinyl DJ, I need the first two digits to show up in program. I do think it not hard to implement. Maybe you could implement a switch to change between integer and double numbers with two digits. DJs will love it!!!! Best ### 5/5 — Timing für Schlagzeuger *2024-04-09* Die App ist eine echte Hilfe, um als Schlagzeuger das Timing zu überprüfen und einzuhalten. Beim Spielen hat man über die Darstellung als Kurve und auch farblich grün oder rot bei zu großen Abweichungen aus dem Augenwinkel heraus direktes Feedback. 😎🥁 ### 5/5 — Incredible App with SP404MKII ETC! *2024-02-14, version 2.6.0* 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! ### 5/5 — Great for keeping you and the band honest. *2024-02-12, version 2.6.0* 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 so BPM 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. ### 4/5 — Nice app with one major pain *2024-01-03, version 2.6.0* I would give this app 5 stars if it would just have a mode like the app liveBPM where it just detects your playing. I try to use this in a band setting but there isn’t time to tap in a target tempo between most songs. ### 4/5 — Nice app with one major pain *2024-01-02* I would give this app 5 stars if it would just have a mode like the app liveBPM where it just detects your playing. I try to use this in a band setting but there isn’t time to tap in a target tempo between most songs. ### 5/5 — Essential Tool! *2023-07-30* There are two tools EVERY musician who wants to improve their tempo needs: a metronome and BeatMirror. A metronome trains you to (re)sync with an external reference. BeatMirror shows you what your internal tempo is and how (un)stable it is. The app interprets tempo accuately even when there are complex rhythms. It’s rock solid and works well in a practice room, rehearsal, and on stage! I highly recommend it!!! ### 3/5 — Gaps in the tracking *2022-11-21, version 2.6.0* I am playing a piece on the piano and I notice when I play the bridge the beat mirror goes gray and only comes back once I exit the bridge the tempo of the bridge never gets tracked ### 5/5 — Great Practice Tool! *2022-09-17, version 2.5.0* Let’s face it, practicing with a metronome is just not enough. This app takes the training wheels off and gives you feedback on your overall pulse. ### 5/5 — Brilliant *2022-07-26, version 2.4.2* I have been looking for a BPM counter that doesn’t require you to tap along for ages. This is great and accurate as well. I have actually tested it using professional music software... and it has not been wrong once yet.. ### 5/5 — Just What My Drum Teaching Studio Needed! *2022-01-31, version 2.4.0* 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! ## Most critical reviews (10 lowest-rated) ### 1/5 — Not as useful as expected *2024-05-11, version 2.6.0* Considering this is a paid for app, rather than free to evaluate etc, this is disappointing. Basically it doesn’t work or at least it isn’t precise enough to measure rapid beats. Even a fairly simple case of physically tapping the microphone to detect a tempo and then doubling this rate results in total confusion in the app - even reporting a slower tempo. I appreciate the effort but it needs more work before charging people for it. ### 1/5 — Does not work with headphones *2022-11-09, version 2.6.0* The app doesn’t work without headphones, which makes it useless for those who wants to try it out while playing along to some songs ### 1/5 — Garbage *2022-10-01, version 2.5.0* Doesn’t work ### 1/5 — 😤DON’T PURCHASE | SCAM 😤 *2022-01-30, version 2.4.0* Not only does this “app” not work. It clearly wasn’t designed to work. You enter a “target” and the “reading” swings back and forth randomly +/- 20. Apple should be aware of this guy having stolen 5 bucks from everyone who purchased this. Is nobody at Apple moderating the store anymore? ### 1/5 — Does not work with acoustic guitar *2021-09-06, version 2.3.0* This app gets lots of love but I can’t get it work with my Martin D28, which is loud. ### 1/5 — Doesn’t do what it claims *2019-11-21, version 2.2.2* It’s won’t pick up the correct bpm by playing it music. Yes my mic is on. ### 1/5 — Lame *2019-05-26, version 2.2.1* Doesn’t work with my iPhone. Tap a bpm hit play, it counts on and then nothing. How do I get my money back??? ### 1/5 — Crap *2019-04-01, version 2.2.1* The app is a piece of not functional CRAP. I bought it to determine beats per minute of songs but I am expected to indicate “count in” beats, whatever that is. I need documentation that has complete sentences with a noun and a verb ### 1/5 — Not worth the price *2018-08-21, version 2.2.0* Huge rip off for what you get. No way to learn the BPM of a song or track a songs BPM without first entering a target BPM... which doesnt make sense since you are trying to find out what that songs bpm is. Also it is incredibly hit or miss (it ignored my pad sound even at loud volumes). If this app is just intended for practicing, it sucks at that too. The app itself has no Metronome capabilities (no sound, visual, haptic etc) so I am not sure how the app expects you to keep on a specific tempo. Really regret purchasing it, they just dont allow refunds (i wonder why..) ### 2/5 — Accurate for Guitar? *2026-03-20, version 3.0.0* I'm trying to use this to get faster at playing guitar and I'm comparing it to my metronome. The beat detection (for me bpm of picking speed) seems inaccurate. Anyone have success with this or suggestions? I'd love for this to work, would be a great tool. ## Most praised reviews (10 highest-rated) ### 5/5 — Fijne app om stabiliteit op ritme te trainen *2026-08-19* De app is eenvoudig te gebruiken en meet het ritme van je muziek, zodat je de stabiliteit daarvan kunt meten en trainen. ### 5/5 — Pretty Nice! *2026-08-04, version 3.0.0* As a songwriter this is a cool app. Gets you in the ballpark of bpm real fast. I usually have to adjust logic drummer just a smidge but not much. Very useful in a creative sense! ### 5/5 — Easy to use *2026-07-01, version 3.0.0* Just open the app and play ### 5/5 — Fantastic drumming tool *2026-05-21, version 3.0.0* This app is a game changer wish I’d had it years ago, I can’t recommend it enough to any drummers, my band mates love it too. Thx for creating it 👍 ### 5/5 — Awesome for guitar rhythm *2026-01-31, version 3.0.0* This is exactly what I was looking for because I’m struggling using a metronome on strum patterns. I can set the target to a songs BPM and practice going through the chord progression over and over and over until my ears and muscle memory kicks in. ### 5/5 — New version makes this superior *2025-10-08, version 3.0.0* 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. ### 5/5 — Great app just have one improvement to mention *2025-09-16, version 3.0.0* I work at a recording studio and use this app all the time to find the proper BPM of songs. It’s golden about 95% of the time. The only issue I run into is with tracks where the BPM lands on a decimal (for example, 120.5). In those cases, the app rounds up or down and doesn’t display the decimal point, which can throw me off briefly during a session. It would be super helpful if a future update added a setting to toggle whether BPM decimals are displayed. That way, users who need the precision can see it right away without second-guessing. Aside from that, the app is fantastic and worth the money. ### 5/5 — Great app *2025-09-06* Have been using for 5 years ### 5/5 — Für Musiker, denen ein Click zu starr ist *2025-08-26* Tolle App, wenn einem der Click im Ohr zu starr ist. Vor allem für Drummer, denen der Rest der Band schon mal gerne davon galoppiert. Zeigt die tatsächliche BPM Zahl an, und dann kann man selbst entscheiden, ob die Schwankung noch im Rahmen ist, oder ob man langsam die Zügel etwas anziehen sollte. ### 5/5 — Great app *2025-04-26, version 3.0.0* I am an intermediate drummer and this app helps me improve my timing. It is one step up from a metronome, BM shows how my timing can waiver and how to bring it back to the speed I want. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
