# ErgData vs ErgZone

ErgData and ErgZone both sit at 4.7 stars, but that hides the real split: 81% of ErgZone's written reviews are positive against 45% of ErgData's. ErgZone also leads on iOS requirement (13.4 vs 16.0). ErgData's advantage is in-app purchases (none vs 2) and update cadence (every 2 weeks vs every 2 months). On price, rating, ads and device support there is nothing between them.

On the App Store both sit at effectively the same score — 4.7 for ErgData against 4.8 for ErgZone. That said, the two scores are not equally well evidenced: ErgData has 5.1K ratings behind it against 458, so its average is the more settled of the two. Written reviews are what separate them: 45% of ErgData's written reviews are positive against 81% of ErgZone's.
