Have a client who does a walk-thru in an office and needs to count furniture items; desks, chairs, etc... on an iPad. Have tried with a script (eg: setField(Desks; Desks + 1), and script trigger (OnObjectEnter running the previous script) which increases the number in a field by the appropriate amount (+1 or +10). Each has a slight lag from first touching the screen to when the amount changes. Would like to have it be more instantaneous. Any ideas?
