# RepZero vs S

The clearest difference is update cadence: S at every 3 days against RepZero's fortnightly. S also leads on iOS requirement (18.0 vs 26.0). RepZero's advantage is device support (3 vs 1). On price, ads and in-app purchases there is nothing between them.

Both are free to download. RepZero sells 2 in-app purchases, starting at $1.99 per month and S sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

RepZero ships an update fortnightly, S every 3 days. The most recent releases landed on October 24, 2026 and October 2, 2026 respectively.
