Verdict
The clearest difference is review sentiment: CT at 100% against IMAIOS e's 48%. CT also leads on in-app purchases (none vs 2) and iOS requirement (13.0 vs 16.6). IMAIOS e's advantage is ads (none vs shown) and update cadence (every 9 days vs every 12 months). On price and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. IMAIOS e sells 2 in-app purchases, starting at $21.99 per month. CT asks for nothing beyond the download.
IMAIOS e holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: IMAIOS e has 1.4K ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 48% of IMAIOS e'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.
IMAIOS e ships an update every 9 days, CT every 12 months. The most recent releases landed on September 26, 2026 and September 9, 2026 respectively.
