# cTrials vs CBT OUcare

The clearest difference is rating: cTrials at 3.0 against CBT OUcare's 2.3. CBT OUcare's advantage is review sentiment (36% vs 0%) and update cadence (every 3 months vs every 12 months). On price, ads, in-app purchases and monetization model there is nothing between them.

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

cTrials holds the better App Store score, 3.0 against 2.3. That said, the two scores are not equally well evidenced: CBT OUcare has 19 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 0% of cTrials's written reviews are positive against 36% of CBT OUcare's, so the app with the better star average is not the one people write more warmly about.

cTrials ships an update every 12 months, CBT OUcare every 3 months. The most recent releases landed on October 9, 2026 and October 16, 2026 respectively.
