# CCU Guide vs Cardiac Trials

The clearest difference is price: CCU Guide at Free against Cardiac Trials's $4.99. CCU Guide also leads on review sentiment (100% vs 78%). Cardiac Trials's advantage is in-app purchases (none vs 5) and ads (none vs shown). On device support and iOS requirement there is nothing between them.

CCU Guide is free to download; Cardiac Trials costs $4.99 up front. CCU Guide sells 5 in-app purchases, starting at $3.79 per year. Cardiac Trials asks for nothing beyond the download.

Cardiac Trials holds the better App Store score, 4.6 against 4.1. Both are backed by a comparable volume of ratings — 14 and 50 respectively. Written reviews complicate that: 100% of CCU Guide's written reviews are positive against 78% of Cardiac Trials's, so the app with the better star average is not the one people write more warmly about.
