# 0 vs sit

The clearest difference is in-app purchases: sit at none against 0's 3. sit also leads on review sentiment (88% vs 59%) and iOS requirement (12.2 vs 16.0). 0's advantage is rating (4.7 vs 4.4) and update cadence (every 2 months vs every 11 months). On price, ads and device support there is nothing between them.

Both are free to download. 0 sells 3 in-app purchases, starting at $4.99 per month. sit asks for nothing beyond the download.

0 holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: 0 has 2.1K ratings behind it against 67, so its average is the more settled of the two. Written reviews complicate that: 59% of 0's written reviews are positive against 88% of sit's, so the app with the better star average is not the one people write more warmly about.

0 ships an update every 2 months, sit every 11 months. The most recent releases landed on October 20, 2026 and October 8, 2026 respectively.
