This is an app for phones and tablets (Android only I’m afraid!) that allows you to maintain and organise a tune library on your device, and do a lot more besides! With support for transposition, playback, mandolin and flute/whistle tablature, a built-in ABC keyboard, sync between devices, access to your library via a web app from any PC, custom sets, ratings, tags and tunebooks, and a lot of options, it’s sure to help you keep track of and finally get round to practising all those tunes…
