ReceptionRating · Positive reviews · Number of ratings

Critical holds the better App Store score, 4.4 against 4.2. Both are backed by a comparable volume of ratings — 268 and 125 respectively. Written reviews complicate that: 43% of Idle Evolution's written reviews are positive against 18% of Critical's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Idle Evolution ships an update every 11 days, Critical fortnightly. The most recent releases landed on October 12, 2026 and October 13, 2026 respectively.
