# В уме vs MAXIMUM

The clearest difference is in-app purchases: В уме at none against MAXIMUM's 10. В уме also leads on ads (none vs shown) and rating (4.8 vs 4.4). MAXIMUM's advantage is update cadence (every 3 weeks vs every 7 months). On price, review sentiment, ratings volume and device support there is nothing between them.

Both are free to download. MAXIMUM sells 10 in-app purchases, starting at $0.99 per month. В уме asks for nothing beyond the download.

В уме holds the better App Store score, 4.8 against 4.4. Both are backed by a comparable volume of ratings — 25 and 13 respectively. Written reviews complicate that: 93% of В уме's written reviews are positive against 100% of MAXIMUM's, so the app with the better star average is not the one people write more warmly about.

В уме ships an update every 7 months, MAXIMUM every 3 weeks. The most recent releases landed on September 19, 2026 and June 1, 2026 respectively.
