Verdict
The clearest difference is monetization model: VidPair at free with in-app purchases against Arm Care's subscription. VidPair also leads on review sentiment (100% vs 74%) and update cadence (every 2 days vs weekly). Arm Care's advantage is chart position (#159 vs unranked) and iOS requirement (15.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
