Verdict

The call

The clearest difference is in-app purchases: OSC Members at none against CharlaViva's 1. OSC Members also leads on iOS requirement (13.0 vs 15.0). CharlaViva's advantage is ads (none vs shown) and update cadence (every 5 days vs every 7 months). On price and device support there is nothing between them.
