Verdict
The clearest difference is ratings volume: Self at 305 against Time Zero's 7. Self also leads on update cadence (weekly vs fortnightly). Time Zero's advantage is iOS requirement (12.0 vs 15.0). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Time Zero sells 10 one-off in-app purchases and Self sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.6 for Time Zero against 4.6 for Self. That said, the two scores are not equally well evidenced: Self has 305 ratings behind it against 7, so its average is the more settled of the two. Written reviews are what separate them: 67% of Time Zero's written reviews are positive against 59% of Self's.
Time Zero ships an update fortnightly, Self weekly. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
