# Notion vs S1 Timer

The clearest difference is rating: Notion at 4.8 against S1 Timer's 1.8. Notion also leads on update cadence (every 3 days vs every 4 months) and ratings volume (90K vs 19). S1 Timer's advantage is in-app purchases (none vs 6) and iOS requirement (11.0 vs 18.0). On price, ads and device support there is nothing between them.

Both are free to download. Notion sells 6 in-app purchases, starting at $9.99 per month. S1 Timer asks for nothing beyond the download.

Notion holds the better App Store score, 4.8 against 1.8. That said, the two scores are not equally well evidenced: Notion has 90K ratings behind it against 19, so its average is the more settled of the two. Written reviews point the same way: 55% of Notion's written reviews are positive against 38% of S1 Timer's.

Notion ships an update every 3 days, S1 Timer every 4 months. The most recent releases landed on October 20, 2026 and October 4, 2026 respectively.
