# REAN AI vs Question.AI

The clearest difference is rating: Question.AI at 4.7 against REAN AI's 4.3. Question.AI also leads on ratings volume (164K vs 19) and chart position (#46 vs unranked). REAN AI's advantage is review sentiment (80% vs 61%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. REAN AI sells 5 one-off in-app purchases and Question.AI sells 19 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Question.AI holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Question.AI has 164K ratings behind it against 19, so its average is the more settled of the two. Written reviews complicate that: 80% of REAN AI's written reviews are positive against 61% of Question.AI's, so the app with the better star average is not the one people write more warmly about.

REAN AI ships an update every 11 days, Question.AI fortnightly. The most recent releases landed on October 17, 2026 and October 31, 2026 respectively.
