Comments on Auto-Key | Music key detection for Android

★★★★★ Mafdy Magdy · Mar 13, 2023

Great app !! Couple of things to consider if this app to be used in a live music environment 1. Add the ability to set the key manually and set the scale with the option to set the scale chromatic. 2. Add eastern makam scales (not sure if they are implemented in antares auto-tune though)

★★★★★ Steven Atamian · Oct 9, 2023

This app is pretty accurate I don't think I've seen it get any keys wrong. 5-star app for sure

★☆☆☆☆ John Hernandez · Aug 4, 2023

I downloaded this app reading all the great reviews. Withing the first 5 songs that I tested out, it always gave me the wrong key. Back to manually figuring out the key.

★☆☆☆☆ Aniruddha Chavan · Jul 11, 2024

All it says is Minor. I tested 10 different songs, and it always said the key is c minor

★☆☆☆☆ Adam G · Sep 6, 2022

Create an account?? Nope. This app is accurate, but after several uses, it demands that you create an account to continue using it. No. Uninstalled it.
