# Milki vs Zen

The clearest difference is in-app purchases: Zen at none against Milki's 3. Milki's advantage is update cadence (fortnightly vs every 6 months) and rating (4.9 vs 4.5). On price, ads and device support there is nothing between them.

Both are free to download. Milki sells 3 in-app purchases, starting at $11.99 per year. Zen asks for nothing beyond the download.

Milki holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: Milki has 107 ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 97% of Milki's written reviews are positive against 80% of Zen's.

Milki ships an update fortnightly, Zen every 6 months. Both last shipped on November 3, 2026.
