I don’t use the app because i can’t properly tune for my solo concertos. ### 2/5 — Directions *2025-05-29, version 1.1.0+2* There are no directions given for using this tuner. It also needs to be adjustable. The goal note needs to be able to be put on repeat so that you don’t have to go back and forth from instrument to phone, to replay the note. ### 3/5 — Fail *2025-02-06, version 1.1.0+2* It helped me tune my A string but it didn’t let me go to the next string! Ts pmo ### 2/5 — Sensitivity *2024-11-03* This app is not sensitive to sound enough. ### 1/5 — BRUHHHHH *2024-06-12, version 1.1.0+2* alr so it’s summer and I need sum to help me tune my cello and this literally did nothing it was supposed to 🤦‍♀️ when I played my D,G,C string it kept telling me my “a” was too low like bruhhh 😑 ## Most critical reviews (10 lowest-rated) ### 1/5 — Cello tuner *2026-07-10, version 4.5.4 (137)* Doesn’t pick up the c string. Works well with g, d, and a. ### 1/5 — Worst experience *2026-03-29, version 4.4.1 (123)* Can’t even tune my C ### 1/5 — Don’t download! *2026-03-22, version 4.4.1 (123)* It wouldn’t recognize the C string at all, when I’d pluck, it would play the C sound but the screen said A and kept telling me to tune both up and down. This app is clueless. ### 1/5 — Bad *2025-12-02, version 1.1.0+2* I used it and it told me to tighten the string and it ended up falling out and I had to go get it fixed. Do not recommend ### 1/5 — C String Fail *2025-10-13, version 1.1.0+2* The app does not recognize the C string. Very bad cello tuner. Not recommended. The good news is that the tuner recognizes all other strings. ### 1/5 — Could not find the changing strings button *2025-09-28, version 1.1.0+2* I finished doing the first string, but I could not find how to tune the rest ### 1/5 — One of the worst tuners I’ve tried *2024-09-10, version 1.1.0+2* It was so slow, some of the buttons wouldn’t work and was so laggy ### 1/5 — this made me mad *2024-08-05, version 1.1.0+2* i had my cello and i could tell it was really out of tune so i downloaded this app. it looked good at first but when i tried it it kept saying that the string was in tune. i could tell it wasn’t because at first it plays what the note is supposed to sound like. the played note sounded nothing like my string it was really annoying. maybe my microphone on my phone wasn’t working or something but this just didn’t work for me ### 1/5 — This broke my C string!!! *2024-07-17, version 1.1.0+2* Thanks a lot 😒 ### 1/5 — Do not recommend *2024-07-05, version 1.1.0+2* This is terrible, completely ruined all of my strings I had my tuner so I could fix them ## Most praised reviews (10 highest-rated) ### 5/5 — The best cello tuner ever *2026-08-01, version 4.5.4 (137)* I highly recommend this app if you don’t know how to tune your cello ### 5/5 — good but funky *2026-06-17, version 4.5.4 (137)* not accurate ### 5/5 — BEST THING EVER TO USE FOR MY CELLO!!! *2025-09-22, version 1.1.0+2* This is something simple and easy to learn and tune. ### 5/5 — New at this! *2024-07-26, version 1.1.0+2* This app is great to get me tuned up to practice as a new player. My piano is way out of tune so I needed a standard. Thank you! ### 5/5 — I love it *2024-04-25, version 1.1.0+2* It helps me tune my cello ### 5/5 — Cello tuner *2024-03-03, version 1.1.0+2* IT HELPED ME SO MUCH TO TUNE MY CELLO THX GUYS! ### 5/5 — Great Tuner *2023-09-14, version 1.0* Tuned my cello and got the job done ✅ ### 4/5 — Love it *2026-08-08, version 4.5.4 (137)* Like a bunch of the cellos in my orchestra class, have it ### 4/5 — It’s pretty good *2024-12-15, version 1.1.0+2* I like this but sometimes it is hard to tell what sound it thinks I’m making because it’s a little late but if you have some patience it’s a really good app for beginners. ### 4/5 — Best tuner I have ever used *2024-11-03, version 1.1.0+2* I have tried lots of different tuners for my cello and this is the best one I have found. It tells you if you are to high or to low. It also gives you a recording of what your string should sound like. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
