The lines data are aggregated from each of the line originators. Line originators are firms that build models and set the odds for each game. Sometimes a line originator is based out of a casino, but often times a casino will purchase the data from a third party firm that specializes in risk managament.
How often does the app update the lines?
Every fifteen minutes.
Will you have opening numbers and line movement?
Opening total for each game is now shown. Plots of line movement over the week is a planned feature.
I have a question or a feature request. How can I contact you?
