# COPD vs VTE Calc

The clearest difference is in-app purchases: COPD at none against VTE Calc's 1. COPD also leads on rating (5.0 vs 4.8). VTE Calc's advantage is update cadence (every 2 days vs every 2 months) and ratings volume (4 vs 1). 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. COPD asks for nothing beyond the download.

COPD holds the better App Store score, 5.0 against 4.8. Both are backed by a comparable volume of ratings — 1 and 4 respectively.

COPD ships an update every 2 months, VTE Calc every 2 days. The most recent releases landed on September 9, 2026 and August 15, 2026 respectively.
