# ErgZone vs Watta

The clearest difference is in-app purchases: Watta at none against ErgZone's 2. Watta also leads on update cadence (every 2 weeks vs every 2 months). ErgZone's advantage is ratings volume (501 vs 1) and device support (4 vs 2). On price, rating and ads there is nothing between them.

Both are free to download. ErgZone sells 2 in-app purchases, starting at $4.99 per month. Watta asks for nothing beyond the download.

Watta holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: ErgZone has 501 ratings behind it against 1, so its average is the more settled of the two.

ErgZone ships an update every 2 months, Watta every 2 weeks. Both last shipped on October 26, 2026.
