Cello Tuner (Free Version) (com.stamselicious.cellotuner) on Google Play
Easy-to-use cello tuner (free version)To use:- Start the app.- Pluck each string.- The app will now show you which strings needs tuning and in which direction.Notes:- The settings do nothing (all suggestions welcome).- The app is for free for now, as we're still not 100% happy with the detection, which is trickier than for a violin due to the low notes. A later/better version (with improved/stable detection) will be released later (expected price: 1£).
