# FieldFab vs Graph Paper Pro

The clearest difference is in-app purchases: FieldFab at none against Graph Paper Pro's 4. FieldFab also leads on rating (4.5 vs 4.1) and ratings volume (79 vs 14). Graph Paper Pro's advantage is update cadence (every 5 days vs every 6 weeks) and review sentiment (67% vs 50%). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Graph Paper Pro sells 4 in-app purchases, starting at $3.99 per month. FieldFab asks for nothing beyond the download.

FieldFab holds the better App Store score, 4.5 against 4.1. That said, the two scores are not equally well evidenced: FieldFab has 79 ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 50% of FieldFab's written reviews are positive against 67% of Graph Paper Pro's, so the app with the better star average is not the one people write more warmly about.

FieldFab ships an update every 6 weeks, Graph Paper Pro every 5 days. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
