# Then vs OS One

The clearest difference is rating: OS One at 5.0 against Then's 4.7. OS One also leads on update cadence (every 4 days vs every 2 weeks). Then's advantage is ratings volume (24 vs 1) and iOS requirement (16.0 vs 26.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Then sells 2 in-app purchases, starting at $2.99 per month and OS One sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

OS One holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Then has 24 ratings behind it against 1, so its average is the more settled of the two.

Then ships an update every 2 weeks, OS One every 4 days. The most recent releases landed on October 24, 2026 and October 15, 2026 respectively.
