Looking for a program for guitar

[Vegitto]

This might be kind of a weird question, but I'm looking for an app that does something like this:

When I feed it some places on the frets, it tells me what scale that's in, or what scale it resembles the most. Hope it's clear what I mean and thanks in advance.

Nothing like that exists as far as I know. The problem is the software wouldn't be able to tell what tones are in what scale as there are modal overlaps between scales. It would be easier to learn the scale patterns. There's lots of mind tricks that you can learn to memorize scales. For instance, the major scales can be laid out like this:

C maj ? 0 sharps
G maj ? 1 sharp ? F#
D maj ? 2 sharps ? F#, C#
A maj ? 3 sharps ? F#, C#, G#
E maj ? 4 sharps ? F#, C#, G#, D#
B maj ? 5 sharps ? F#, C#, G#, D#, A#
F# maj ? 6 sharps ? F#, C#, G#, D#, A#, E#

If you can learn these 7 lines, you can build on them. For instance, the minor pentatonic scale uses tones 1,3b,4,5, and 7b. So, in the key of C (C, D, E, F, G, A, B), the minor pentatonic would be C, Eb, F, G, Bb.

It's kind of like learning the rules of the alphabet, but you only have to learn 7 letters
