A cellular or Wi-Fi Internet connection is required for real time Stats and Scheme data. The time from entering data to visibility by other team members is directly related to the strength of your Internet connection.
Filmroom includes a network monitor with clear status indicators so you never have to guess about your Internet connection strength:
Good (Wi-Fi) - no indicator. Data transfer is fast.
Good (Cellular) - blue indicator. You'll want to be sure you're comfortable with your data usage and resulting network carrier fees.
Poor - orange indicator. Data transfer is slow. Filmroom will work in this state but you should your expectations for speed pretty low.
Offline - red indicator. No Internet connection means no real time data.
