unhexennium app for iPhone and iPad

Unhexennium (IUPACs name for the 169th element) is an ad-free, open-source, offline chemistry calculator.

It provides support for:

* Chemical element
- location on the periodic table
- name
- chemical symbol
- atomic number
- relative atomic mass
- electronegativity
- electron configuration (abbreviated, box and arrow)
- common oxidation states and ions
* Chemical formula
- name(s)
- relative formula mass
- empirical formula
- percentage by mass of the constituent atoms
- oxidation states of the constituent atoms
- bond type
- mass / mole calculations
- ideal gas calculations (PV = nRT)
* Chemical equation
- equation balancer (redox reactions are supported)
- mass / mole calculations
- limiting reactant
- atom economy

This application is developed using googles new mobile framework, flutter. The source code is available on https://github.com/Mapioi/unhexennium.
