Both are free to download. Vimi sells 7 in-app purchases, starting at $19.99 per month. Astral Tutor asks for nothing beyond the download.
Vimi holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Vimi has 974 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 60% of Vimi's written reviews are positive against 100% of Astral Tutor's, so the app with the better star average is not the one people write more warmly about.
Vimi ships an update every 8 days, Astral Tutor daily. The most recent releases landed on October 18, 2026 and October 14, 2026 respectively.
