Isotopia is an isotopic distribution calculator and plotter, a molecular mass calculator and an isotopes database.
Its features include:
— calculating average, monoisotopic and most probable mass
— plotting isotopic distribution
— high-precision table of isotopic distribution peaks
— elemental weight composition
— database of isotopes and natural abundance
Calculations stay instantaneous up to 10,000s atoms on your iPhone/iPod.
Isotopia is an equivalent of "iMass" for iPhone.
