If you have an iPhone or iPad ( or iPod Touch) check out Pitchlab: https://itunes.apple.com/us/app/pitchlab-guitar-tuner-free/id732850624?mt=8
Basic app is free but you’ll probably want to spend the three bucks and get the full set of displays. Easy to set up, lots of useful things, especially a strobe tuner display. …Bob To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
