# Astra AI vs StudyNotes AI

The clearest difference is ads: StudyNotes AI at none against Astra AI's shown. StudyNotes AI also leads on rating (5.0 vs 4.8). Astra AI's advantage is update cadence (every 4 days vs every 5 weeks) and ratings volume (3.9K vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Astra AI sells 10 in-app purchases, starting at $8.00 per 7 days and StudyNotes AI sells 3 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

StudyNotes AI holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Astra AI has 3.9K ratings behind it against 1, so its average is the more settled of the two.

Astra AI ships an update every 4 days, StudyNotes AI every 5 weeks. The most recent releases landed on September 24, 2026 and August 5, 2026 respectively.
