Narrative:

While programming both the FMS and [tablet application] efb; found that J110 appeared to be missing (it was present on the appropriate jeppesen high chart). Was only able to find the airway after zooming in to less than 6 mile range. [Tablet application] efb needs to be much more complete regarding the marking of airways; both high and low enroute. There are many examples of airway markings that do not appear until zooming in on the chart beyond a point that almost everything else becomes unviewable. Additionally; the symbology being used; especially for VOR/VORTAC/TACAN are the same at any basic intersection. This makes the potential for navigation error much greater.additionally; the screen size with the ipad mini is unacceptable; as it requires 'pinching and zooming' for just simple basic viewing of the associated approach chart/SID/STAR. This condition is much less pronounced on the standard sized ipad screen. I've had occurrences on every single segment flown where basic data; normally viewable on a standard navigational document; disappears from view because of the requirement to 'pinch and zoom' simply to make individual items viewable.
