Chemical Solution Simple helps in preparation of chemical solution by dissolution of solid solute or by dilution of existing solution and in finding of moles, Molar masses, required weights of solutes and volumes of starting solutions. Supported concentration units are Molar (M), mM, uM, g/l, mg/l. Touch the units field to change the units in the aformentioned order. The app includes Molar Mass Analyser. Tap on arrow in the Mw field initiates analysis of chemical formula in the component field and set the value to Mw field. No charge values should be used. Valid examples: Mg(HCO3)2, CaCl2.2H2O, CaCl2*2H2O, (NH4)2Fe(SO4)2.6H2O, Mg(H2PO4)2, C6H12O6. Analyser is case sensitive. Application assigns dot as a decimal separator.

Verdict
Civil Engineering Calculators and Chemical Solution Simple both sit at 4.8 stars, but that hides the real split: 100% of Chemical Solution Simple's written reviews are positive against 0% of Civil Engineering Calculators's. Chemical Solution Simple also leads on price ($2.99 vs $19.99) and update cadence (every 3 months vs every 14 months). Civil Engineering Calculators's advantage is ratings volume (12 vs 1). On rating, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Civil Engineering Calculators costs $19.99 and Chemical Solution Simple $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Chemical Solution Simple holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Civil Engineering Calculators has 12 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 0% of Civil Engineering Calculators's written reviews are positive against 100% of Chemical Solution Simple's.
Civil Engineering Calculators ships an update every 14 months, Chemical Solution Simple every 3 months. The most recent releases landed on November 4, 2026 and November 2, 2026 respectively.
