# Zef vs Updraft

The clearest difference is rating: Updraft at 5.0 against Zef's 4.6. Zef's advantage is ratings volume (41 vs 1) and device support (5 vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Zef sells 3 in-app purchases, starting at $6.99 per month and Updraft sells 4 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Updraft holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Zef has 41 ratings behind it against 1, so its average is the more settled of the two.

Zef ships an update fortnightly, Updraft weekly. Both last shipped on November 2, 2026.
