Scale Finder and FretBoard Map
I made an excel program back in 2012, to find what chords fit a particular key or a particular scale and where to find them in a guitar fret-board. It's only for 4 scales, Major, Minor, Harmonic Minor and Blues. (Haven't had the time to add modes or exotic scales, or pentatonic scales even) It's pretty easy to use. You just pick a particular key. Like C or D# etc. Then you pick a scale. (Major, Minor, Harmonic Minor) Then thats it. A guitar fret-board will show which particular note you'll have to use in the fret-board to stay in key Anyways, it's not much. but it may help you somehow It's in this link: https://drive.google.com/file/d/0B9YSodwjXVZdRmQ4QVgzVVFtTVE PS: this assumes you're on a 6 string guitar, on standard tuning only I like to think of this now as my gift to the music world.
