A260 app for iPhone and iPad

This app calculates the solution concentration of a nucleic acid (DNA, RNA) or nucleotide from an absorbance measurement at 260 nm.
Dilution factors can be automatically calculated from stock and final volumes.

The app operates in
one of two modes: novice and expert.

In novice mode, the user is guided by a question and answer format.

In expert mode the user can enter parameters in any order as well as:
- Set the dilution volume units
- Set the spectrophotometer path length
- Set low and high limits for warning the user when an absorbance reading is outside the recommended range.
