However, there’s an electronic buzzing going on and it doesn’t seem to allow tuning. Also, really, really weird that there’s no reviews. ### 1/5 — Nur noch Schrott *2024-10-14, version 2.4* Seit dem neuen iOS funktioniert es nicht mehr und obwohl ich bezahlt habe verlangt man dass ich es wieder kaufen muss. Das ist glatter Betrug. ### 1/5 — No custom tuning *2023-10-05* No way to do custom tuning! ### 5/5 — Exceeds expectations *2020-08-07* Works as expected therefore it exceeds my expectations as opposed to most crap apps ### 5/5 — 10 string Yepes tuning *2020-06-07* Can you please update for the 10-string Yepes tuning? ### 5/5 — Good App ! *2020-03-02, version 2.3* Goog App! ### 5/5 — Good tuner! *2020-02-17* Out of all the other tuner apps I’ve tried and used this is the most accurate! Many of the other tuners doesn’t put my guitar in to or near perfect tune like this app. ### 2/5 — heidiandbunji1 *2018-08-10* Can not use for a guitalele **Developer response:** Thanks for suggestion. We will add "guitalele" next update version. ### 5/5 — This app is helpful. *2018-07-09* This app is good if you don’t have an “actual” tuner I suggested this app to my friends and they liked it! ## Frequently asked questions about GuitarTuner ### Does GuitarTuner have ads?
