# Knot Guide vs Calculator‰

The clearest difference is price: Calculator‰ at Free against Knot Guide's $2.99. Calculator‰ also leads on in-app purchases (none vs 2) and ratings volume (410K vs 451). Knot Guide's advantage is ads (none vs shown) and update cadence (monthly vs every 5 months).

Calculator‰ is free to download; Knot Guide costs $2.99 up front. Knot Guide sells 2 in-app purchases, starting at $2.99 per month. Calculator‰ asks for nothing beyond the download.

Calculator‰ holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Calculator‰ has 410K ratings behind it against 451, so its average is the more settled of the two. Written reviews complicate that: 79% of Knot Guide's written reviews are positive against 70% of Calculator‰'s, so the app with the better star average is not the one people write more warmly about.

Knot Guide ships an update monthly, Calculator‰ every 5 months. The most recent releases landed on October 31, 2026 and November 4, 2026 respectively.
