Verdict

The call

Yuno and memoryOS both sit at 4.8 stars, but that hides the real split: 80% of memoryOS's written reviews are positive against 53% of Yuno's. memoryOS also leads on device support (3 vs 1) and iOS requirement (15.2 vs 18.0). Yuno's advantage is update cadence (every 5 days vs every 3 weeks). On price, rating, ratings volume and ads there is nothing between them.
