# One Second vs Second By Second

The clearest difference is review sentiment: Second By Second at 100% against One Second's 31%. Second By Second also leads on rating (5.0 vs 4.5) and update cadence (daily vs every 5 weeks). One Second's advantage is ratings volume (3.6K vs 1) and iOS requirement (13.0 vs 18.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. One Second sells 8 in-app purchases, starting at $7.99 per month and Second By Second sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Second By Second holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: One Second has 3.6K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 31% of One Second's written reviews are positive against 100% of Second By Second's.

One Second ships an update every 5 weeks, Second By Second daily. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
