# VisiGrab vs FlutterLab

The clearest difference is rating: VisiGrab at 4.8 against FlutterLab's 3.7. VisiGrab also leads on review sentiment (88% vs 67%) and ratings volume (74 vs 3). FlutterLab's advantage is in-app purchases (none vs 1) and update cadence (every 5 days vs fortnightly). On price, ads and device support there is nothing between them.

Both are free to download. VisiGrab sells 1 one-off in-app purchase. FlutterLab asks for nothing beyond the download.

VisiGrab holds the better App Store score, 4.8 against 3.7. That said, the two scores are not equally well evidenced: VisiGrab has 74 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 88% of VisiGrab's written reviews are positive against 67% of FlutterLab's.

VisiGrab ships an update fortnightly, FlutterLab every 5 days. The most recent releases landed on September 18, 2026 and August 31, 2026 respectively.
