Verdict

The call

The clearest difference is review sentiment: Activity Trackr at 100% against Calendars's 56%. Activity Trackr also leads on rating (5.0 vs 4.7) and iOS requirement (15.1 vs 18.2). Calendars's advantage is ratings volume (122K vs 2) and update cadence (weekly vs every 2 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.
