# ATracker Time Tracker vs Ultradian

The clearest difference is rating: ATracker Time Tracker at 4.7 against Ultradian's 3.3. ATracker Time Tracker also leads on update cadence (fortnightly vs every 5 months) and ratings volume (3.2K vs 4). Ultradian's advantage is in-app purchases (none vs 3) and ads (none vs shown). On price and review sentiment there is nothing between them.

Both are free to download. ATracker Time Tracker sells 3 in-app purchases, starting at $2.99 per month. Ultradian asks for nothing beyond the download.

ATracker Time Tracker holds the better App Store score, 4.7 against 3.3. That said, the two scores are not equally well evidenced: ATracker Time Tracker has 3.2K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 92% of ATracker Time Tracker's written reviews are positive against 100% of Ultradian's, so the app with the better star average is not the one people write more warmly about.

ATracker Time Tracker ships an update fortnightly, Ultradian every 5 months. The most recent releases landed on October 19, 2026 and September 29, 2026 respectively.
