# Uknow.AI vs Answer.AI

The clearest difference is ratings volume: Answer.AI at 166K against Uknow.AI's 4.2K. Answer.AI also leads on chart position (#192 vs unranked). Uknow.AI's advantage is update cadence (weekly vs every 3 weeks) and iOS requirement (13.0 vs 18.0). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Uknow.AI sells 10 in-app purchases, starting at $8.99 per month and Answer.AI sells 10 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for Uknow.AI against 4.7 for Answer.AI. That said, the two scores are not equally well evidenced: Answer.AI has 166K ratings behind it against 4.2K, so its average is the more settled of the two. Written reviews are what separate them: 78% of Uknow.AI's written reviews are positive against 75% of Answer.AI's.

Uknow.AI ships an update weekly, Answer.AI every 3 weeks. The most recent releases landed on November 6, 2026 and November 9, 2026 respectively.
