# Abstruct vs Vaultica

The clearest difference is rating: Vaultica at 5.0 against Abstruct's 4.3. Vaultica also leads on update cadence (every 2 months vs every 4 months) and device support (3 vs 1). Abstruct's advantage is monetization model (free with in-app purchases vs subscription) and ratings volume (18 vs 1). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Abstruct sells 3 in-app purchases, starting at $0.99 per month and Vaultica sells 1 in-app purchase, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Vaultica holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Abstruct has 18 ratings behind it against 1, so its average is the more settled of the two.
