Narrative:

I flew four flights utilizing the ipad efb comparing that to the jeppesen paper charts twice. Many differences/discrepancies are noted from today's flying.lga: there are no windsocks noted on the ipad 10-1 page for lga. There are no ramp location numbers noted anywhere in lga. These are found on other cities. This is crucial for pilots who are not familiar. The tennis 5 departure page is cluttered. Compare this to the jeppesen. This is an RNAV departure. Fix bearings from vors do not need to be printed. As with many other charts; VOR depictions on the tennis 5 are denoted as triangle fixes. However; lga VOR is denoted as a circle. This is inconsistent. Most of those vors are not even depicted on the jepp as they are unnecessary since it's an RNAV sid. The climb out is the 134 heading then left turn to two fixes. The fixes do not have the altitude restrictions in the inset; yet they are present as part of the main page. The speed restriction at jutes is also not present in the inset. The whole purpose of an inset is to make larger; and clearer. But to not publish this critical information in the inset is confusing and inconsistent.mip arrival: some vors are published as a fix triangle; such as allentown (fjc); while soldberg (sbj) is a circle. Consistency is not present. As with most sids and stars; all the mileage between fixes are rounded to whole numbers whereas the jeppesen charts provide to the 1st decimal place; such as 12.3 DME there is less precision in these charts.pit: demme 2 arrival. On the jepps; the arrival name is clear; center; and bold. On the ipad; its sideways and small print. As with other complaints; vors are inconsistent; even from different charts. Here ihd VOR is depicted as a star; which is different than triangles on other charts; and different from mmj VOR which is a circle on this page. Again; all distances around rounded and not precise to one decimal place. Example; on the jepp; the distance from vinse to ejocy is 66.9 NM on the jepps; and 67 on the ipad. The hold at pleez shows to hold at 210 knots. The jeppesen shows it as a maximum hold of 210 knots from 6001 feet to 14;000 feet. Ipad misses the altitudes. The textual description is simply missing on the ipad.the ramp frequencies are not found on the airport diagram page as compared to phl. The ramp frequencies are listed on the general page. This is not user friendly and could be a safety hazard if one has to be constantly flipping pages to find necessary information. It requires too much heads down.fix these and many other issues before turning off the jeppesen subscription.
