# Math Solver vs Ring Sizer

The clearest difference is monetization model: Ring Sizer at free with in-app purchases against Math Solver's subscription. Ring Sizer also leads on rating (4.9 vs 4.7). Math Solver's advantage is update cadence (monthly vs every 2 months). On price, review sentiment, ratings volume and in-app purchases there is nothing between them.

Both are free to download. Math Solver sells 1 in-app purchase, starting at $4.99 per 7 days and Ring Sizer sells 6 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Ring Sizer holds the better App Store score, 4.9 against 4.7. Both are backed by a comparable volume of ratings — 29 and 33 respectively. Written reviews complicate that: 96% of Math Solver's written reviews are positive against 90% of Ring Sizer's, so the app with the better star average is not the one people write more warmly about.

Math Solver ships an update monthly, Ring Sizer every 2 months. Both last shipped on October 24, 2026.
