Thermodynamics Calculator vs BeamLog

Thermodynamics Calculator puts 44 thermodynamics and heat-transfer calculators — plus a library of thermal engineering reference tables — in one fast, offline app for engineers and students. Sizing a heat exchanger, checking a Carnot efficiency, or looking up the emissivity of a material? You get the formula, the result, and the reference data in seconds. WHY ENGINEERS USE IT • Solve for any variable — on most calculators, rearrange the formula and solve for whichever value you're missing, not just the "standard" output. • SI and USCS (Imperial) units — switch the whole app between metric and imperial with one tap; every input, result, and unit label updates instantly. • Reference tables built in — emissivity coefficients, thermal conductivity of common liquids and heat-exchanger materials, radiation constants, and more. • Find it fast — search plus category filters: Heat Transfer, Thermal Expansion, Radiation, Energy & Work, Dimensionless Numbers, Properties & Tables. WHO IT'S FOR Mechanical, chemical, and HVAC engineers, and thermodynamics / heat-transfer students who want quick, reliable answers without digging through a textbook.

BeamLog is an offline notebook for laser cutter and engraver settings. Every time you dial in a new material, save the power, speed, passes, focus and air assist you used, the machine you ran it on, and a photo of the test swatch. Next time that material comes up, you look it up instead of testing it again. BUILT AROUND ITERATION Most tests are not one-offs. Open an entry, tap Duplicate, and a new form opens pre-filled with every value from the old test. Change the one number you want to try, take a new photo of the swatch, save. Both runs sit next to each other in the log, so you can see how the setting developed instead of guessing where you left off. WORKS WITH ANY MACHINE BeamLog is vendor-neutral. You name your own machine profiles (diode, CO2 or fiber) and enter your own values, so it fits whatever is on your bench. It ships no preset catalogue and recommends nothing — the only numbers you ever see are the ones you measured yourself. Over time that becomes a material library you can actually trust, because every entry in it came off your own machine. FEATURES - Log power, speed, passes, focus and air assist per test - Record material and thickness for every entry - One photo per test, taken in the app or picked from your library - Mark each run as success, partial or failed - Duplicate any entry as the starting point for the next run - Search across material, machine and notes - Filter by machine, material and result - Machine profiles for diode, CO2 and fiber lasers - CSV export of the full log via the share sheet - Works completely offline, with no account and no sign-up PRICING Ten entries and one machine profile are free. A single purchase unlocks unlimited entries, unlimited machine profiles and CSV export. There is no subscription: BeamLog runs entirely on your device, so there are no running costs to pass on. Restore Purchases brings the unlock to your other devices. YOUR DATA Entries and photos are stored on your phone. Nothing is uploaded, there is no server and no sync, and the app works the same in airplane mode as it does at home.
