Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
