The clearest difference is price: Anchor Pro at Free against Knot Guide's $2.99. Anchor Pro also leads on rating (4.8 vs 4.6) and ratings volume (3.5K vs 450). Knot Guide's advantage is update cadence (monthly vs every 2 months). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.

Anchor Pro holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Anchor Pro has 3.5K ratings behind it against 450, so its average is the more settled of the two. Written reviews split almost evenly too, at 80% and 79% positive.

Knot Guide ships an update monthly, Anchor Pro every 2 months. The most recent releases landed on September 24, 2026 and September 23, 2026 respectively.
