Fail
Im a life-long Peterson user (since 1978); Ive need had cause to look elsewhere for a tuner.
Until now.
As a guitarist I find this app fails -- even with the additional purchase of the Sweeteners -- to provide a solid tune.
Far from it.
One strum after verifying all strings hold tune with no abrupt swing sharp and a proper decay flat says it all: my instrument(s) are unplayable after a strobe app tune.
Fail.
