# On/Off vs Gate Master

The clearest difference is ads: On/Off at none against Gate Master's shown. Gate Master's advantage is update cadence (every 3 days vs every 29 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

On/Off ships an update every 29 months, Gate Master every 3 days. The most recent releases landed on November 1, 2026 and November 10, 2026 respectively.
