Irish Whistle Tabs is an open-source and ad-free tool to learn and improve your tin whistle skills. It features hundreds of traditional Celtic tunes (jigs, reels, polkas, ballads, etc.). To play along, you can change the whistle key (high D by default) and the tempo. A delay can be added to get time to pick up the whistle. This app is ad-free, fully offline and very lightweight (<3 Mo). More tunes and features to come! Code source on Github, GPLv2 licence: https://github.com/CGrassin/tinwhis
