Verdict

The call

The clearest difference is in-app purchases: TruckIT Viewer at none against Calendars's 10. TruckIT Viewer also leads on iOS requirement (13.0 vs 18.2). Calendars's advantage is update cadence (weekly vs every 5 weeks) and chart position (#108 vs unranked). On price and ads there is nothing between them.
