Verdict
The clearest difference is review sentiment: ATrack Online at 100% against Acellus's 36%. Acellus's advantage is rating (4.5 vs 4.0) and ratings volume (32K vs 1). On price, update cadence, ads and in-app purchases 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. Neither carries in-app purchases, so what you see is what you pay.
Acellus holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Acellus has 32K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 36% of Acellus's written reviews are positive against 100% of ATrack Online's, so the app with the better star average is not the one people write more warmly about.
Acellus ships an update every 3 months, ATrack Online every 2 months. The most recent releases landed on September 25, 2026 and June 2, 2026 respectively.
