# Algorithms HQ vs VisiGrab

The clearest difference is rating: VisiGrab at 4.8 against Algorithms HQ's 4.0. VisiGrab also leads on update cadence (every 3 weeks vs every 16 months) and ratings volume (74 vs 1). Algorithms HQ's advantage is in-app purchases (none vs 1) and review sentiment (100% vs 88%). On price, ads and iOS requirement there is nothing between them.

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

VisiGrab holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: VisiGrab has 74 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Algorithms HQ's written reviews are positive against 88% of VisiGrab's, so the app with the better star average is not the one people write more warmly about.

Algorithms HQ ships an update every 16 months, VisiGrab every 3 weeks. The most recent releases landed on September 24, 2026 and October 6, 2026 respectively.
