After 5 or 6 times trying and still not getting the dots in the right place (they appeared to be vertical), I resorted to a Google search to find out more instructions, to find nothing. Please fix this! ### 4/5 — Great! *2019-09-15, version 1.2* Awesome app, but i wish it had more chords to choose from. ex: 9/11/13 ### 4/5 — Great for beginners *2019-07-22* Don’t get me wrong I wished I had this when I was learning my first chords but the app is quite limited. I’d like to see sus chords, and more jazz chords. ### 1/5 — Still doesn’t work *2018-12-29, version 1.2* With the most recent update it still doesn’t align properly with my Korg SV-1 ### 1/5 — Developer Responded...doesn’t work still *2018-11-24, version 1.2* The developer responded months back, and I did what they said and it still doesn’t work correctly on my iPhone X for my smaller Keyboard! Fix is needed ### 4/5 — All in one *2018-11-21* Nice most useful for lovers of music ### 2/5 — Trop sommaire *2018-11-11* Il n’y a que les accords basiques. L’app sera intéressante quand on pourra rechercher tous les accords (9e, 11e, 13e, altérées, diminués, augmentés,...) et leurs renversements ### 1/5 — Good concept, not good app *2018-11-07* I went through the calibration steps but the chords weren’t even close to the right keys. Plus there’s no way to recalibrate that I could see. Also the chord selection is fairly limited - major, minor, diminished, and the basic 7th chords. Not even a m7-flat 5 as an option. There’s definitely potential for something useful so let’s hope it keeps getting updates. ### 4/5 — Helpful! Looking forward to future updates *2018-11-04* Enjoying the app. Looking for 9ths, 11ths, and 13ths to be added sometime. Excited for what the team does with this app. ### 1/5 — Doesn’t work *2018-09-16, version 1.11* Doesn’t work, that is sad tried getting for special needs daughter no she is sad ## Most critical reviews (10 lowest-rated) ### 1/5 — Kalibrierung funktioniert bei mir auch nicht *2022-09-08* Schade, nachdem ich die Tiefste und die höchste Taste definiere, scheint die App zu glauben, dass Piano stünde um 90 ° gedreht. So nützt mir die App gar nicht. 🙁 ### 1/5 — Not calibrating *2022-05-28, version 1.2* Not calibrating. It move dot perpendicular to what it should be moving ### 1/5 — Doesn’t work *2020-12-29, version 1.2* Never could get it to align. It always thinks the keyboard is sideways no matter what. ### 1/5 — Won’t pick up the piano *2020-06-03, version 1.2* This App is awful. I’ve been scanning across the piano for 10 minutes, and it will not pick up the piano. DO NOT GET THIS APP ### 1/5 — Totally broken *2020-05-29, version 1.2* Yeah, this worked about as good as I thought it would. Couldn’t even calibrate it. ### 1/5 — Doesn’t work anymore, please fix! *2020-05-16, version 1.2* This app used to work 6 months ago but, now it just view keys from the side. Please fix this app ### 1/5 — Doesn’t align at all *2020-03-11, version 1.2* Tried a bunch of different ways. Just doesn’t work at all. ### 1/5 — Doesn’t work at all *2020-02-26, version 1.2* The dots won’t align with the piano; they keep facing perpendicular to the piano. ### 1/5 — Problem with the app *2019-12-29* The app seems like i could be really helpful for beginners but when it told me to align it it would not have the dots on the actual piano it. It had them going the opposite side and i try over and over again go get it to work but I couldn’t get it on the keys. ### 1/5 — It’s a trick to take your money nothing happens -1 *2019-05-10* The keys never show ## Most praised reviews (10 highest-rated) ### 5/5 — Cool app *2023-07-22, version 1.2* I really like this app ### 5/5 — Love it *2021-09-11, version 1.2* I love it so much tanks for making it ### 5/5 — It works *2020-02-29, version 1.2* For realfrthdo ### 5/5 — THANK YOU! *2019-08-19, version 1.2* BEEN LOOKING AND DOWNLOADING SO MANY APPS TO LEARN BASIC KEYS FOR FREE AND I HAVE FINALLY FOUND THE ONE. HAHA thanks xxxx ### 5/5 — I don’t spend time to write reviews *2019-06-19* This app is amazing. It gives a great reminder to my prior piano memory and opportunity to anyone trying to learn. It will allow for anyone new to easily learn chords. Fantastic job, I’m well impressed on the work as a developer myself. It allows you to learn and easily adapts to the camera position you place it in. There was likely good testing on this app (although small stuff like small keyboards may show sharp notes out of place); but it is one of the best implementations of AR I have seen thus far. Bravo. ### 5/5 — Amazing and has potential *2018-11-16* I was in the App Store searching some sort of chord dictionary and I stumbled across this wonderful app. Calibration was perfect and quick. My only gripe with it is that if only it had more complex extended chords for jazz harmonies this app would be bolstered to an even more unique and amazing app. ### 5/5 — Cool idea. Works great! *2018-11-12* This is a really cool idea. The old version didn’t align to my keyboard, but the new update works great! Thanks for the update :) **Developer response:** Hi j999, The latest version of Tonic should work with your keyboard. Try it out! If this works for you, would you mind revising your review? Thanks! ### 5/5 — Great application of AR *2018-09-20, version 1.11* Works well, really cool concept. ### 5/5 — Awesome! *2018-09-15* It’s working! Makes learning piano more comfortable and efficient. **Developer response:** Hi Ariyala2000, Sorry about that. The latest version of the app should fix this issue. Try it out! If this works for you, would you mind revising your review? ### 5/5 — Coole Sache *2018-09-15* Klappt super, freue mich auf zukünftige Updates, keep it up bro --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
