# Spaced Repetition vs Math Solver

The clearest difference is rating: Spaced Repetition at 5.0 against Math Solver's 4.1. Spaced Repetition also leads on monetization model (free vs free with in-app purchases) and iOS requirement (17.2 vs 26.0). Math Solver's advantage is ratings volume (16 vs 2). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Spaced Repetition sells 6 in-app purchases, starting at $1.99 per month and Math Solver sells 3 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Spaced Repetition holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: Math Solver has 16 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 95% of Spaced Repetition's written reviews are positive against 100% of Math Solver's, so the app with the better star average is not the one people write more warmly about.

Spaced Repetition ships an update every 10 days, Math Solver every 2 weeks. Both last shipped on October 28, 2026.
