Pythagorean Tuner is a precision tuner for violinists, cellists, violists, bassists, and singers who play in true Pythagorean intonation, built on pure 3:2 perfect fifths. Unlike equal-tempered tuners, it places every sharp and flat at its true, distinct pitch, so a flat sits lower than its enharmonic sharp, just as string players hear it.

Verdict
The clearest difference is price: Pythagorean Tuner at Free against sinusedo's $3.99. Pythagorean Tuner also leads on rating (5.0 vs 4.7). sinusedo's advantage is ratings volume (7 vs 1) and device support (4 vs 1). On review sentiment, update cadence, ads and in-app purchases there is nothing between them.
