# AcadAI vs SciSpace

The clearest difference is rating: AcadAI at 4.6 against SciSpace's 3.2. AcadAI also leads on review sentiment (48% vs 13%) and ratings volume (2K vs 6). SciSpace'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. SciSpace asks for nothing beyond the download.

AcadAI holds the better App Store score, 4.6 against 3.2. That said, the two scores are not equally well evidenced: AcadAI has 2K ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 48% of AcadAI's written reviews are positive against 13% of SciSpace's.

AcadAI ships an update weekly, SciSpace fortnightly. The most recent releases landed on September 24, 2026 and September 9, 2026 respectively.
