Still going strong - the paid version of the Hot Apps winner is still the best guitar tuner for webOS! This update now saves your last used tuning so you don't have to switch it every time you open the app. Tap the strings to play the proper sounds and tune your guitar to that pitch. Tap the orange button at the bottom of the screen to choose from 11 tunings - yes, now Open E tuning is included for slide guitar! If you have any issues, choose Support from the drop-down menu at the top-left of the screen in the app.
