# Question.AI vs Studdy

Question.AI and Studdy both sit at 4.7 stars, but that hides the real split: 89% of Studdy's written reviews are positive against 61% of Question.AI's. Question.AI's advantage is ratings volume (164K vs 13K) and chart position (#44 vs unranked). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Question.AI sells 19 in-app purchases, starting at $6.99 per 7 days and Studdy sells 35 in-app purchases, starting at $1.99 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 — 4.7 for Question.AI against 4.8 for Studdy. That said, the two scores are not equally well evidenced: Question.AI has 164K ratings behind it against 13K, so its average is the more settled of the two. Written reviews are what separate them: 61% of Question.AI's written reviews are positive against 89% of Studdy's.

Question.AI ships an update fortnightly, Studdy every 10 days. Both last shipped on October 24, 2026.
