Steam Tables calculates the functions below, using the IAPWS-97 equations: •Function(p,t) – to calculate properties from pressure and temperature; •Function(p,h) – to calculate properties from pressure and enthalpy; •Function(p,s) – to calculate properties from pressure and entropy; •Function(p,x) – to calculate properties from pressure and quality; •Function(t,x) – to calculate properties from temperature and quality; •Function(h,s) – to calculate properties from entalpy and entropy. From the functions above, you can calculate quickly the properties below: •Pressure; •Temperature; •Enthalpy; •Entropy; •Quality; •Specific Volume; •Internal Energy; •Density; •See the current region. •Use multiple units. The best thermodynamic properties calculation in the App Store!!!!!

Verdict
The clearest difference is in-app purchases: SPK at none against Steam Tables Lite's 1. SPK also leads on ads (none vs shown) and update cadence (fortnightly vs every 2 months). On price and device support there is nothing between them.
