# ErgZone vs PocketCox

The clearest difference is ratings volume: ErgZone at 458 against PocketCox's 15. ErgZone also leads on iOS requirement (13.4 vs 17.0). PocketCox's advantage is update cadence (every 3 weeks vs every 2 months). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. ErgZone sells 2 in-app purchases, starting at $4.99 per month and PocketCox sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for ErgZone against 4.9 for PocketCox. That said, the two scores are not equally well evidenced: ErgZone has 458 ratings behind it against 15, so its average is the more settled of the two. Written reviews are what separate them: 81% of ErgZone's written reviews are positive against 86% of PocketCox's.

ErgZone ships an update every 2 months, PocketCox every 3 weeks. The most recent releases landed on September 27, 2026 and September 13, 2026 respectively.
