# Thrombosis Guidelines vs VTE Calc

The clearest difference is in-app purchases: Thrombosis Guidelines at none against VTE Calc's 1. VTE Calc's advantage is update cadence (every 2 days vs every 12 months) and iOS requirement (9.0 vs 12.0). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. VTE Calc sells 1 one-off in-app purchase. Thrombosis Guidelines asks for nothing beyond the download.

Thrombosis Guidelines ships an update every 12 months, VTE Calc every 2 days. The most recent releases landed on June 5, 2026 and August 15, 2026 respectively.
