Verdict
RSTR and Studio Three both sit at 5.0 stars, but that hides the real split: 100% of RSTR's written reviews are positive against 55% of Studio Three's. RSTR also leads on device support (3 vs 1) and iOS requirement (14.0 vs 16.0). Studio Three's advantage is ads (none vs shown) and ratings volume (1.3K vs 9). On price, rating, update cadence and in-app purchases there is nothing between them.
