What Key Is This Progression Actually In?
Most key finders match scales and give you a confident-looking answer. Fretscape asks what the progression actually suggests - and tells you how sure it is.
The Wrong Name, Ranked First
Hand a reverse chord lookup three notes and it leads with C6(no3) over the obvious Am7 - then warns about its own answer. Lookup isn't the problem. Ranking is.

I sat down to take one screenshot for the Play Store. Three hours later I'd fixed three bugs in the optimiser - and was very late for a family day out.
