# Populations and Resources Sim vs SyncGrades

The clearest difference is rating: SyncGrades at 3.7 against Populations and Resources Sim's 2.3. SyncGrades also leads on update cadence (every 2 months vs every 4 months) and device support (3 vs 1). Populations and Resources Sim's advantage is ratings volume (47 vs 6) and iOS requirement (12.0 vs 15.0). On price, review sentiment, ads and in-app purchases there is nothing between them.

SyncGrades holds the better App Store score, 3.7 against 2.3.

Written reviews complicate that: 39% of Populations and Resources Sim's written reviews are positive against 33% of SyncGrades's, so the app with the better star average is not the one people write more warmly about.
