# ErgZone vs Lung Rot

The clearest difference is ratings volume: ErgZone at 458 against Lung Rot's 4. ErgZone also leads on device support (4 vs 1) and iOS requirement (13.4 vs 26.0). Lung Rot's advantage is update cadence (every 11 days vs every 2 months) and rating (5.0 vs 4.8). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. ErgZone sells 2 in-app purchases, starting at $4.99 per month and Lung Rot sells 2 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Lung Rot holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: ErgZone has 458 ratings behind it against 4, so its average is the more settled of the two.

ErgZone ships an update every 2 months, Lung Rot every 11 days. The most recent releases landed on October 11, 2026 and October 8, 2026 respectively.
