# SYSTEM AI vs Mastermind

SYSTEM AI and Mastermind both sit at 4.4 stars, but that hides the real split: 80% of SYSTEM AI's written reviews are positive against 64% of Mastermind's. SYSTEM AI also leads on update cadence (every 2 weeks vs monthly). Mastermind's advantage is ratings volume (53 vs 14) and iOS requirement (15.1 vs 18.0). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. SYSTEM AI sells 4 in-app purchases, starting at $6.99 per 7 days and Mastermind sells 9 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Mastermind holds the better App Store score, 4.6 against 4.4. Both are backed by a comparable volume of ratings — 14 and 53 respectively. Written reviews complicate that: 80% of SYSTEM AI's written reviews are positive against 64% of Mastermind's, so the app with the better star average is not the one people write more warmly about.

SYSTEM AI ships an update every 2 weeks, Mastermind monthly. The most recent releases landed on June 4, 2026 and September 23, 2026 respectively.
