Coating development

Using it to measure the density of black coatings. So far it’s working beautifully and giving us good measurable data.

I received my Spectro early - unbelievable for the price. App is very well done.

Crash happy, needs landscape on iPad

Every time I tap a color chit to view details on the paint color, the app crashes for both iPhone and iPad. The iPad app needs to be landscape aware.
