Verdict
The clearest difference is in-app purchases: Runners Calculator at none against MidLab's 2. Runners Calculator also leads on iOS requirement (12.0 vs 15.1). MidLab's advantage is ads (none vs shown) and update cadence (daily vs every 2 weeks). On price and device support there is nothing between them.
