# Deep Sea Defender vs Polycell

The clearest difference is ads: Deep Sea Defender at none against Polycell's shown. Polycell's advantage is update cadence (every 3 weeks vs every 108 months) and iOS requirement (11.0 vs 13.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Deep Sea Defender sells 4 one-off in-app purchases and Polycell sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Deep Sea Defender ships an update every 108 months, Polycell every 3 weeks. The most recent releases landed on October 1, 2026 and October 3, 2026 respectively.
