# I vs AcadAI

The clearest difference is rating: AcadAI at 4.6 against I's 3.7. AcadAI also leads on update cadence (weekly vs every 2 months) and ratings volume (2K vs 3). I's advantage is in-app purchases (none vs 9). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. AcadAI sells 9 in-app purchases, starting at $9.99 per 7 days. I asks for nothing beyond the download.

AcadAI holds the better App Store score, 4.6 against 3.7. That said, the two scores are not equally well evidenced: AcadAI has 2K ratings behind it against 3, so its average is the more settled of the two.

I ships an update every 2 months, AcadAI weekly. The most recent releases landed on June 19, 2026 and September 24, 2026 respectively.
