Verdict
The clearest difference is rating: FieldLevel at 4.9 against b4's 4.2. FieldLevel also leads on in-app purchases (none vs 4) and ratings volume (2.7K vs 152). b4's advantage is update cadence (every 3 weeks vs every 3 months). On price, review sentiment and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. b4 sells 4 in-app purchases, starting at $3.99 per month. FieldLevel asks for nothing beyond the download.
FieldLevel holds the better App Store score, 4.9 against 4.2. That said, the two scores are not equally well evidenced: FieldLevel has 2.7K ratings behind it against 152, so its average is the more settled of the two. Written reviews complicate that: 71% of FieldLevel's written reviews are positive against 79% of b4's, so the app with the better star average is not the one people write more warmly about.
FieldLevel ships an update every 3 months, b4 every 3 weeks. The most recent releases landed on November 10, 2026 and November 12, 2026 respectively.
