Specialized on high frequency electronics for RF professionals, radio amateurs and students. RF-Toolbox is based on the popular Electronic Toolbox by Marcus Roskosch. This app contains some of the common tools of Electronic Toolbox but contains a wide range of additional tools, specialized for high frequency electronics, RF professionals, radio amateurs and students. Currently RF-Toolbox consists of more than 90 tools and like Electronic Toolbox, there are more to come over the time. Feature list: ■ PCB Trace Width (Internal and external Traces) ■ PCB Trace Resistance ■ PCB Trace Impedance (various trace types e.g. Microstrip, embedded Microstrip, Symmetric and Asymetric Stripline, Wire Microchip, Wire Stripline, Edge Coupled Microstrip and Stripline) PCB Crosstalk (Microstrip and Stripline) ■ LC L/T/Pi Match calculation ■ Coax Cable calculation (Standard and individual Types) ■ Amplifier and Attenuator cascade calculation ■ SWR / Reflection / Return loss conversion ■ Power Divider (Branchline, Ratrace and Wilkinson) ■ Capacitor Plate calculation ■ RLC Parallel, Series and Circuit calculation ■ Noise Figure conversion ■ Skin Depth calculation (various materials from Aluminum to Silver) ■ Butterworth Filter (also with plot of filter chart) ■ Chebyshev Filter (also with plot of filter chart) ■ R-C, L-C, R-L High/Low/Band-Pass Filter ■ RF Units conversion (quick conversion of frequently used units) ■ Air coil inductance calculation ■ Resistors, Capacitors, Inductors in Parallel / Series And there is much more... ■ Aktive Filter calculation tool ■ Antenna calculation tool ■ Delta Star calculation ■ Cable length / ampacity tool ■ PTC / NTC Temperature Resistance conversion ■ AC Ohms law tool ■ Zener diode circuit calculation ■ Constant current source tool ■ ASCII Table ■ Desktop calculator ■ Resistor/Capacitor/Inductor combinations tool ■ 4-20mA conversion tool ■ Passive cooling calculator ■ Audio Oscilloscope Please check out more screen shots on my website (WEBSITE Link on the left side).

Verdict
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.
