Verdict
The clearest difference is price: SmartLab35 at Free against mySpotMeter's $6.99. SmartLab35 also leads on iOS requirement (16.0 vs 26). mySpotMeter's advantage is update cadence (every 2 days vs every 5 weeks) and chart position (#56 vs unranked). On ads, in-app purchases and device support there is nothing between them.
