# Notra vs Zachet

The clearest difference is rating: Notra at 5.0 against Zachet's 4.6. Zachet's advantage is ratings volume (57 vs 1) and update cadence (every 4 days vs every 10 days). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Notra sells 2 in-app purchases, starting at $8.99 per month and Zachet sells 4 in-app purchases, starting at $17.99 per month. Whichever you choose, the download price is not the number that matters.

Notra holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Zachet has 57 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 75% of Notra's written reviews are positive against 86% of Zachet's, so the app with the better star average is not the one people write more warmly about.

Notra ships an update every 10 days, Zachet every 4 days. Both last shipped on November 13, 2026.
