# Idle Anomaly vs Sol Frontiers

The clearest difference is rating: Idle Anomaly at 4.7 against Sol Frontiers's 4.2. Sol Frontiers's advantage is review sentiment (59% vs 38%) and update cadence (fortnightly vs every 5 weeks). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Idle Anomaly sells 10 one-off in-app purchases and Sol Frontiers sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Idle Anomaly holds the better App Store score, 4.7 against 4.2. Both are backed by a comparable volume of ratings — 364 and 122 respectively. Written reviews complicate that: 38% of Idle Anomaly's written reviews are positive against 59% of Sol Frontiers's, so the app with the better star average is not the one people write more warmly about.

Idle Anomaly ships an update every 5 weeks, Sol Frontiers fortnightly. Both last shipped on November 3, 2026.
