# Escape vs Zero/Sum

The clearest difference is ads: Zero/Sum at none against Escape's shown. Zero/Sum also leads on update cadence (every 2 months vs every 14 months) and iOS requirement (8.0 vs 15.6). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Escape ships an update every 14 months, Zero/Sum every 2 months. The most recent releases landed on November 9, 2026 and November 2, 2026 respectively.
