The app is useful for the fluid thinkers. This app covers a wide variety of topics and helps in analysis, design, maintenance and operation of fluid related systems. The calculator will provide results for different fluid mechanics, civil, structural, pipe flow and engineering parameters. It is useful in the fields of automotive, aviation, geology, space, biological applications, petroleum, marine systems and cylinder manufacturing. This app comes handy to students, engineers, analysts, researchers and the curious. Here are the useful features of this app LISTS 130+ FORMULAE Memorizing hundreds of formula is not the way to go when it comes to learning fluid mechanics 360+ METHODS OF CALCULATION This calculator allows a user to change subject of formula based on the variable he/she wants to calculate. The formula applied is displayed in the app CALCULATE FOR ANSWERS Key in the numbers, set units and see results. Switch upto three conversion units. The app accepts input and provides results to the highest mathematical precision MARK FAVORITES Easy markups for easy recall HOP SEAMLESSLY BETWEEN BETWEEN METRIC AND US (INCH) UNIT SYSTEMS The app maintains separate functioning of these unit systems. The app has a predefined library of units designated to each of them It would be a good idea to kill the app and re-open it once in a while with the internet. We constantly strive to update, increase and enrich the content of the app. Go fluid with this app in your pocket!
ProcessChem

ProcessChem puts a chemical engineer's property tables, equation-of-state solvers, and unit-operation calculators in your pocket — no spreadsheet, no lookup binder, no internet connection required. PROPERTY LOOKUPS Pull density, viscosity, thermal conductivity, heat capacity, vapor pressure, heat of vaporization, compressibility factor, and surface tension for thousands of pure chemicals and mixtures. Hazard and safety data included: flash point, flammability limits, exposure limits, and carcinogen/GWP/ODP flags. PHASE EQUILIBRIUM & FLASH CALCULATIONS Run flash calculations across any two-property target — temperature, pressure, enthalpy, entropy, internal energy, or volume — to find the resulting phase state and composition. Powered by CoolProp's reference-quality equations of state for over 100 fluids, with a Peng-Robinson backend covering the rest. REACTIONS & EQUILIBRIUM Balance chemical reactions automatically, track excess reagent and conversion, and run full energy balances. A dedicated equilibrium solver finds multi-species reaction composition at any temperature and pressure. An electrochemistry mode computes cell voltage and electron balances for electrolysis and battery chemistry. MULTI-COMPONENT MIXTURES Peng-Robinson with ChemSep binary interaction parameters, bubble/dew point calculations, and per-component hazard data — across every mode in the app. PROCESS ENGINEERING CASES - Vessel leak estimation: give a vessel's contents, initial conditions, and a leak opening (or target final pressure), and get back leak rate, mass discharged, and time to depressurize — adiabatic or isothermal, with optional pressure-regulator (PRV) modeling - Fluidized bed design: Geldart classification, minimum fluidization velocity, elutriation, and multi-species reacting beds UNITS, YOUR WAY A dedicated Units tab lets you pick your preferred unit for every quantity in the app, with a configurable Normal/Standard reference for gas-volume conversions. Built for process, chemical, and plant engineers, students, and anyone who needs a real thermodynamic answer faster than a lookup table can give one.

Verdict
The clearest difference is iOS requirement: ProcessChem at 13.0 against Fluid Mechanics Calc's 15.6. On price, ads, in-app purchases and device support there is nothing between them.
