# Cronometer vs Nu

The clearest difference is ads: Nu at none against Cronometer's shown. Nu also leads on review sentiment (100% vs 69%) and rating (5.0 vs 4.8). Cronometer's advantage is ratings volume (100K vs 35) and update cadence (weekly vs every 3 weeks). On price, in-app purchases, monetization model and iOS requirement there is nothing between them.

Both are free to download. Cronometer sells 8 in-app purchases, starting at $10.99 per month and Nu sells 7 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

Nu holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Cronometer has 100K ratings behind it against 35, so its average is the more settled of the two. Written reviews point the same way: 69% of Cronometer's written reviews are positive against 100% of Nu's.

Cronometer ships an update weekly, Nu every 3 weeks. The most recent releases landed on November 6, 2026 and November 5, 2026 respectively.
