# Field Tools vs Digital DoF

The clearest difference is in-app purchases: Field Tools at none against Digital DoF's 16. Field Tools also leads on ads (none vs shown) and rating (4.9 vs 4.6). Digital DoF's advantage is update cadence (monthly vs every 5 months) and ratings volume (274 vs 9). On price and device support there is nothing between them.

Both are free to download. Digital DoF sells 16 one-off in-app purchases. Field Tools asks for nothing beyond the download.

Field Tools holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Digital DoF has 274 ratings behind it against 9, so its average is the more settled of the two. Written reviews point the same way: 78% of Field Tools's written reviews are positive against 70% of Digital DoF's.

Field Tools ships an update every 5 months, Digital DoF monthly. Both last shipped on October 29, 2026.
