Verdict

The call

Acellus and Co both sit at 4.5 stars, but that hides the real split: 75% of Co's written reviews are positive against 36% of Acellus's. Acellus's advantage is ads (none vs shown) and ratings volume (32K vs 7). On price, rating, update cadence and in-app purchases there is nothing between them.

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

ReceptionRating · Positive reviews · Number of ratings

Acellus holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Acellus has 32K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 36% of Acellus's written reviews are positive against 75% of Co's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on November 1, 2026 and October 24, 2026 respectively.
