# Pavlok vs Flow

The clearest difference is review sentiment: Pavlok at 69% against Flow's 17%. Pavlok also leads on rating (4.5 vs 4.1) and ratings volume (3.2K vs 395). Flow's advantage is update cadence (every 3 days vs every 2 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Pavlok sells 6 in-app purchases, starting at $4.99 per month and Flow sells 6 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Pavlok holds the better App Store score, 4.5 against 4.1. That said, the two scores are not equally well evidenced: Pavlok has 3.2K ratings behind it against 395, so its average is the more settled of the two. Written reviews point the same way: 69% of Pavlok's written reviews are positive against 17% of Flow's.

Pavlok ships an update every 2 weeks, Flow every 3 days. The most recent releases landed on November 13, 2026 and November 9, 2026 respectively.
