# iRadTech Lite vs CT

The clearest difference is review sentiment: CT at 100% against iRadTech Lite's 25%. CT also leads on ratings volume (12 vs 4). iRadTech Lite's advantage is rating (5.0 vs 4.5) and ads (none vs shown). On price, update cadence, in-app purchases and device support there is nothing between them.

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

iRadTech Lite holds the better App Store score, 5.0 against 4.5. Both are backed by a comparable volume of ratings — 4 and 12 respectively. Written reviews complicate that: 25% of iRadTech Lite's written reviews are positive against 100% of CT's, so the app with the better star average is not the one people write more warmly about.
