# Lost Sock vs Responsibility Zero

The clearest difference is ads: Responsibility Zero at none against Lost Sock's shown. Responsibility Zero also leads on update cadence (daily vs every 5 weeks) and rating (4.9 vs 4.6). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Lost Sock sells 1 one-off in-app purchase 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. That said, the two scores are not equally well evidenced: Responsibility Zero has 831 ratings behind it against 35, so its average is the more settled of the two. Written reviews complicate that: 81% of Lost Sock'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.

Lost Sock ships an update every 5 weeks, Responsibility Zero daily. The most recent releases landed on September 27, 2026 and September 28, 2026 respectively.
