# Sub vs Mill

The clearest difference is review sentiment: Mill at 62% against Sub's 15%. Mill also leads on monetization model (free vs ad-supported). Sub's advantage is rating (4.4 vs 4.2) and ratings volume (788 vs 95). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Sub holds the better App Store score, 4.4 against 4.2. That said, the two scores are not equally well evidenced: Sub has 788 ratings behind it against 95, so its average is the more settled of the two. Written reviews complicate that: 15% of Sub's written reviews are positive against 62% of Mill's, so the app with the better star average is not the one people write more warmly about.

Sub ships an update every 5 weeks, Mill monthly. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
