# Caption AI vs Aether

The clearest difference is update cadence: Aether at every 4 days against Caption AI's fortnightly. Caption AI's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Caption AI ships an update fortnightly, Aether every 4 days. The most recent releases landed on October 24, 2026 and October 8, 2026 respectively.
