# Nekosan vs Responsibility Zero

The clearest difference is ads: Responsibility Zero at none against Nekosan's shown. Responsibility Zero also leads on update cadence (daily vs every 2 months) and rating (4.9 vs 4.6). On price, review sentiment, ratings volume and in-app purchases there is nothing between them.

Both are free to download. Nekosan sells 5 one-off in-app purchases and Responsibility Zero sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Responsibility Zero holds the better App Store score, 4.9 against 4.6. Both are backed by a comparable volume of ratings — 869 and 831 respectively. Written reviews complicate that: 83% of Nekosan's written reviews are positive against 77% of Responsibility Zero's, so the app with the better star average is not the one people write more warmly about.

Nekosan ships an update every 2 months, Responsibility Zero daily. The most recent releases landed on September 30, 2026 and October 2, 2026 respectively.
