# ErgData vs CrewLAB

The clearest difference is update cadence: CrewLAB at daily against ErgData's every 2 weeks. CrewLAB also leads on review sentiment (75% vs 45%). ErgData's advantage is ratings volume (5.1K vs 98) and rating (4.7 vs 4.4). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

ErgData holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: ErgData has 5.1K ratings behind it against 98, so its average is the more settled of the two. Written reviews complicate that: 45% of ErgData's written reviews are positive against 75% of CrewLAB's, so the app with the better star average is not the one people write more warmly about.

ErgData ships an update every 2 weeks, CrewLAB daily. The most recent releases landed on September 29, 2026 and September 26, 2026 respectively.
