# Unit Ease vs Secure App

The clearest difference is rating: Unit Ease at 5.0 against Secure App's 3.8. Unit Ease also leads on ratings volume (67 vs 4) and device support (4 vs 1). Secure App's advantage is update cadence (every 4 days vs every 4 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Unit Ease sells 1 one-off in-app purchase and Secure App sells 3 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Unit Ease holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: Unit Ease has 67 ratings behind it against 4, so its average is the more settled of the two.

Unit Ease ships an update every 4 weeks, Secure App every 4 days. The most recent releases landed on October 24, 2026 and October 31, 2026 respectively.
