# TowerTank vs On\Off

The clearest difference is in-app purchases: On\Off at none against TowerTank's 1. On\Off also leads on update cadence (daily vs every 2 days) and ratings volume (8 vs 1). TowerTank's advantage is iOS requirement (9.0 vs 14.0). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. TowerTank sells 1 one-off in-app purchase. On\Off asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for TowerTank against 5.0 for On\Off. That said, the two scores are not equally well evidenced: On\Off has 8 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

TowerTank ships an update every 2 days, On\Off daily. The most recent releases landed on June 10, 2026 and June 11, 2026 respectively.
