# ATracker Time Tracker vs Calflow

The clearest difference is ads: Calflow at none against ATracker Time Tracker's shown. Calflow also leads on rating (4.9 vs 4.7). ATracker Time Tracker's advantage is ratings volume (3.2K vs 121) and iOS requirement (15.0 vs 17.0). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. ATracker Time Tracker sells 3 in-app purchases, starting at $2.99 per month and Calflow sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Calflow holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: ATracker Time Tracker has 3.2K ratings behind it against 121, so its average is the more settled of the two. Written reviews complicate that: 93% of ATracker Time Tracker's written reviews are positive against 88% of Calflow's, so the app with the better star average is not the one people write more warmly about.

ATracker Time Tracker ships an update every 2 weeks, Calflow every 10 days. The most recent releases landed on September 25, 2026 and September 21, 2026 respectively.
