"ChemTable" is a new and free android app I just launched. I would really love for people to check out my work, give suggestions for new features, bug reports, findings of incorrect data, and feedback; I hope it is very useful, especially if you're the type to have your phone with you during your experiments and/or forget your periodic table/datasheets and/or not bring a calculator when making a solution. (*note: there is an ad, you have been warned!!!)

- Solution creation, dilution, and buffer pH calculators
- Periodic data on 118 chemical elements including sample photographs, Bohr diagrams, electronic configuration, physical, electrical, bonding, thermodynamic, and reactivity properties
