For simple piano music it gives wildly different results when checking the same piece. The piano keyboard displayed is far too quiet - even with the speaker next to my ear - then of course I cannot see the keys. ### 3/5 — Fails *2026-05-31, version 1.1.0* Will not allow sign or reset password! ### 2/5 — Another account driven app *2026-04-04, version 1.1.0* Starts off well - but after a few uses request to make an account. If something’s free you are the commodity. ### 2/5 — No good results *2026-01-04, version 1.1.0* I tested on some reggae tunes I know the keys of, but it failed and after a few attempts I should have had to register. Nonsense. ### 4/5 — Excellent utility *2025-12-30, version 1.1.0* I’m impressed! Very accurate results. It would be even more valuable if was able to display the Camelot key too. ### 4/5 — Please add camelot and bpm *2025-09-20, version 1.1.0* Works! But seeing bpm and Camelot world be next level!!! ### 3/5 — Accessibility *2025-07-30, version 1.1.0* As a user with low vision, the app was accessible for me — which was great. I came back to use it today and was asked to create an account. However, I cannot see the small faint font to do this. Now I’m locked out. ### 2/5 — What for? *2025-05-14, version 1.1.0* The App only detects the main key a piece is written in. Why do I need an app for that? If I know the concert pitch A then I just listen a couple of seconds and know the key. I had hoped that the app would spit out the chord progression of a song. That would be useful. ### 1/5 — Sign in to use *2024-12-29, version 1.1.0* Why do I have to create an account to use the app for free? Ridiculous. ### 1/5 — 数回で *2024-11-27, version 1.1.0* 使用出来なくなりました。 英語だらけで意味不明 ## Most critical reviews (10 lowest-rated) ### 1/5 — Terrible *2026-06-27, version 1.1.0* This is the worst app that’s ever been made, it’s only job is to find the key of whatever music is being played and still gets it wrong regularly, how has this been passed? It’s faulty ### 1/5 — Help *2026-06-23, version 1.1.0* Love it, won’t let me register, won’t let me reset password, won’t let me log in, infinitely stuck not being able to use it :( ### 1/5 — Rather pay than sign up *2026-06-05, version 1.1.0* Can i just pay for the app and not make a login? I don’t understand why key detection requires a username and password. I liked this app before this change because it was simple to use, with no extra stuff. Now idk ### 1/5 — Wrong Keys *2026-04-09, version 1.1.0* I tried this app, every single song I sung, it gave me the wrong key. And besides that the app is slow. They say perfect pitch in your pocket… someone with perfect pitch will know the key almost instantly. This requires like 10 seconds of singing… just to give you the wrong key. Imagine how embarrassing it would be if a tone deaf person were relying on this app in a Live Musical Setting. ### 1/5 — Doesn’t work *2026-03-12, version 1.1.0* Keys are usually wrong ### 1/5 — So many questions *2025-10-01, version 1.1.0* Why do I need an account for this? What does me having an account add to my experience? How many nights has the developer spent crying alone in bed? ### 1/5 — Was great, now not *2025-09-27, version 1.1.0* Great app, until it asked to create account - buggy and can’t access the new account. ### 1/5 — Didn’t work for me *2025-09-14, version 1.1.0* Tried 4 times with one song and came up with 3 different keys, none of which matched official key. ### 1/5 — Waste of your time *2025-08-21, version 1.1.0* Totally disgusting. Apple should really remove companies like this from the platform. Originally, I gave this app a glowing review, only to discover that after a handful of uses it goes for the data grab. You will be blocked from using it unless you give over your data. ### 1/5 — Seems pretty handy for picking harmonica keys *2025-06-30, version 1.1.0* After I used it a few times it blocked me and wanted me to sign up. The agreement to continue using it gives up all my information they collect to 3rd parties. What a shame; I deleted the app. I was looking forward to using it. I would pay a small fee if it didn’t require giving up my information and constantly get bugged by 3rd parties… ## Most praised reviews (10 highest-rated) ### 5/5 — Bring auto tune to ipad *2026-05-08, version 1.1.0* Hi, please bring auto tune. iPad would be amazing to have it and if you have any vocal sinking tools, you can bring as well. It would be very useful. ### 5/5 — Tut was es soll *2025-09-12, version 1.1.0* Eine App gesucht, die über Mikrofon die Tonart eines Liedes erkennt. Klappt super👍🏻 ### 5/5 — The key to the keys *2025-04-23, version 1.1.0* I wish the app could be my ears It’s been spot on for me. Simple. Quick. Shows keys on keyboard for more novice players of piano. Nice to have when wanting to jam with some Spotify musicians that I dig. Fun. Thanks for the key to the keys ### 5/5 — Parfait *2025-04-10, version 1.1.0* Fonctionne parfaitement bien ### 5/5 — Useful app! *2025-04-02, version 1.1.0* I find myself using this tool a few times a month, usually when learning new songs in the guitar. It helps to get confirmation you’re in the right key ### 5/5 — Got it right most times *2025-02-04, version 1.1.0* You have to try it more than once to get reliable results, but most of the time it works. It's nice that you can see the key on the piano, so you can easily determine whether the key is correct. ### 5/5 — The Gold Standard. Fast & No Frills. *2024-10-08, version 1.1.0* Can’t wait to see what they do next. ### 5/5 — Easy and actually works *2024-10-08, version 1.1.0* Use it every day for instruments and vocals ### 5/5 — Auto-Key *2024-10-08, version 1.1.0* Super helpful product, great job ### 5/5 — Great app for making music !!!! *2024-10-08, version 1.1.0* Love this app. Helps me with my vocals and ties into Auto Tune seamlessly. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
