# MocapX vs On‑Device AI

The clearest difference is rating: On‑Device AI at 4.4 against MocapX's 3.2. On‑Device AI also leads on update cadence (fortnightly vs every 2 months) and review sentiment (64% vs 47%). MocapX's advantage is iOS requirement (15.0 vs 18.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. MocapX sells 6 in-app purchases, starting at $19.99 per month and On‑Device AI sells 4 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

On‑Device AI holds the better App Store score, 4.4 against 3.2.
