Verdict

The call

The clearest difference is review sentiment: RF at 91% against Fluke Connect's 6%. RF also leads on rating (4.9 vs 4.4) and iOS requirement (11.1 vs 13.1). Fluke Connect's advantage is price (Free vs $7.99) and update cadence (every 5 weeks vs every 4 months). On ads, in-app purchases and device support there is nothing between them.
