# On‑Device AI vs Babel Fish

The clearest difference is update cadence: Babel Fish at every 3 days against On‑Device AI's fortnightly. On‑Device AI's advantage is device support (4 vs 2) and iOS requirement (18.0 vs 26.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. On‑Device AI sells 4 in-app purchases, starting at $3.99 per month and Babel Fish sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On‑Device AI ships an update fortnightly, Babel Fish every 3 days. The most recent releases landed on October 24, 2026 and September 30, 2026 respectively.
