# Compare Flow vs QField for QGIS

The clearest difference is rating: Compare Flow at 4.6 against QField for QGIS's 4.1. Compare Flow also leads on iOS requirement (15.1 vs 17.0). QField for QGIS's advantage is update cadence (every 6 days vs every 32 months) and ratings volume (37 vs 5). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Compare Flow holds the better App Store score, 4.6 against 4.1. That said, the two scores are not equally well evidenced: QField for QGIS has 37 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 50% of Compare Flow's written reviews are positive against 56% of QField for QGIS's, so the app with the better star average is not the one people write more warmly about.

Compare Flow ships an update every 32 months, QField for QGIS every 6 days. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
