# Ag PhD Field Guide vs Quick Commodities

The clearest difference is rating: Quick Commodities at 4.3 against Ag PhD Field Guide's 2.5. Quick Commodities also leads on update cadence (fortnightly vs every 3 months) and ratings volume (505 vs 8). Ag PhD Field Guide's advantage is in-app purchases (none vs 6) and review sentiment (50% vs 24%). On price, ads and device support there is nothing between them.

Both are free to download. Quick Commodities sells 6 in-app purchases, starting at $2.99 per month. Ag PhD Field Guide asks for nothing beyond the download.

Quick Commodities holds the better App Store score, 4.3 against 2.5. That said, the two scores are not equally well evidenced: Quick Commodities has 505 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 50% of Ag PhD Field Guide's written reviews are positive against 24% of Quick Commodities's, so the app with the better star average is not the one people write more warmly about.

Ag PhD Field Guide ships an update every 3 months, Quick Commodities fortnightly. The most recent releases landed on September 15, 2026 and September 22, 2026 respectively.
