Verdict
The clearest difference is in-app purchases: O2 Car Control at none against RingCalendar's 2. O2 Car Control also leads on iOS requirement (17.6 vs 26.5). RingCalendar's advantage is update cadence (every 3 days vs every 4 months). On price, ads and device support there is nothing between them.
