Built for engineering students

Clean interface, step-by-step calculations, and comprehensive thermodynamic tables.

Capabilities

Every cycle your textbook covers

From introductory thermodynamics to advanced power systems — all with step-by-step state calculations.

What's new

Process Solver and full imperial units for every student, plus Pro depth for combined cycles, psychrometrics, and advanced refrigeration.

Free Process Solver — closed or steady-flow single processes with end state, work and heat
Settings SI / Imperial toggle — psi/psig, °F/°R, Btu/h, lbm/h (solver stays SI)
Pro: psychrometrics, combined cycle, Brayton IC/RH, two-stage economizer, CO₂ booster
Multi-gas variable specific heats and Rankine real-condition modes

Fully translated interface including all cycle diagrams, labels, and UI elements.

Settings toggle for SI or Imperial — psi/psig, °F/°R, Btu/h, lbm/h. Solver stays SI internally.

All calculations run on-device. No analytics, no tracking, no accounts required.

Uses published steam tables and R-134a data with standard thermodynamic formulas.

Free to download. Three cycles included free — unlock more with optional in-app purchases.
