# Thrombosis vs The Calgary Guide

The clearest difference is rating: The Calgary Guide at 4.4 against Thrombosis's 4.0. Thrombosis's advantage is review sentiment (75% vs 67%). On price, ratings volume, update cadence and ads there is nothing between them.

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

The Calgary Guide holds the better App Store score, 4.4 against 4.0. Both are backed by a comparable volume of ratings — 3 and 8 respectively. Written reviews complicate that: 75% of Thrombosis's written reviews are positive against 67% of The Calgary Guide's, so the app with the better star average is not the one people write more warmly about.

Thrombosis ships an update every 5 months, The Calgary Guide every 4 months. The most recent releases landed on October 8, 2026 and October 22, 2026 respectively.
