Verdict

The call

The clearest difference is ads: Oshi Fan Log at none against Oshi's shown. Oshi Fan Log also leads on device support (3 vs 1) and iOS requirement (16.0 vs 26.2). Oshi's advantage is update cadence (daily vs every 2 days). On price and in-app purchases there is nothing between them.
