# Astra AI vs Mindfly

The clearest difference is in-app purchases: Mindfly at none against Astra AI's 10. Mindfly also leads on rating (5.0 vs 4.8). Astra AI's advantage is ratings volume (5.6K vs 3) and chart position (#203 vs unranked). On price, update cadence, ads 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. Mindfly asks for nothing beyond the download.

Mindfly holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Astra AI has 5.6K ratings behind it against 3, so its average is the more settled of the two.

Astra AI ships an update every 9 days, Mindfly weekly. The most recent releases landed on November 8, 2026 and November 5, 2026 respectively.
