# Data Structure Display vs VisiGrab

The clearest difference is update cadence: VisiGrab at fortnightly against Data Structure Display's every 5 months. VisiGrab also leads on review sentiment (88% vs 62%) and rating (4.8 vs 4.5). Data Structure Display's advantage is ratings volume (676 vs 74) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Data Structure Display sells 1 one-off in-app purchase and VisiGrab sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

VisiGrab holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Data Structure Display has 676 ratings behind it against 74, so its average is the more settled of the two. Written reviews point the same way: 62% of Data Structure Display's written reviews are positive against 88% of VisiGrab's.

Data Structure Display ships an update every 5 months, VisiGrab fortnightly. The most recent releases landed on September 24, 2026 and September 18, 2026 respectively.
