The Molecular Weight Calculator is a physics/math tool designed to find the average molecular weight (MW) of molecules by inputting their chemical formulas. Features: - Instant calculation - Results can be copied to other apps - Includes formula references - Supports up to 16 decimal places - Works seamlessly on both iPhone and iPad. - Lightweight, compact app optimized for everyday use. - Ad-free and built with privacy in mind. Note: Chemical formulas are case-sensitive (e.g., C22H30N4O). Definitions: - Molecular mass (molecular weight): The mass of one molecule of a substance, expressed in unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12) - Molar mass (molar weight): The mass of one mole of a substance, expressed in grams per mole (g/mol). Thank you for your support!

Verdict
The clearest difference is update cadence: TC at every 3 months against Molecular Weight Calculator's every 29 months. TC also leads on price ($1.99 vs $2.99). Molecular Weight Calculator's advantage is ratings volume (3 vs 1). On rating, ads, in-app purchases and monetization model there is nothing between them.
