I've used both and prefer ForeFlight as a whole. The only feature I really enjoy on Jeppesen FD is the one that allows writing on plates.

I'm getting into Foreflight right now. It's tough to beat, but never tried Jepps product. I've used most the others in trial months though but am going with FF.

I'd highly recommend the Jeppesen Mobile Flight Deck for a number of reasons, first and foremost, the enroute charts are generated on the fly, not just a raster image that is rotated to align with the flight track. That way things in the enroute structure always read right side up. Also, you are getting better data in my opinion as it has been ingested and analysed for accuracy by Jepp rather than blindly spit back out by FF or any other app that just reuses FAA provided data.

As far as cost, you can get a an Express subscription that will include 4-5 states for between $80 and $160 per year, and that would include being able to print them out on their software if you wanted a backup (which I would highly recommend).

Hope that helps!

Reuses FAA provided data?
Where do you think Jepps gets its data?
Unless they develop and publish their own approaches (of which I believe there are a few) - Jepps gets their info from the FAA and puts it into a different format - otherwise it is the same info - presented differently.

Don't worry - there are errors in the FAA data too and probably the same in the Jepps data.

What I was trying to get at is that Jepp data has been looked over by humans before being published. I doubt Fore flight does that.

I am unfamiliar with the Jepps process.
I know that the FAA products are looked over by humans - I'm one of them.
It was my understanding that Jepps gets that information from the FAA and then publishes it in their own unique formatting style.
Are you saying that Jepps then verifies the information again after getting it from the FAA?
If so - since I don't have any access to Jepps - I'd like to try a little experiment. Could someone copy and paste, or send a link that I could access, to the A/FD 'Remarks' section for Garden City, KS from the Jepps plates.

I've used ForeFlight for the past couple years and can't say enough good about it. They're always updating with new features. That said, it's not going to help with transitioning to Jepp charts at all...

Slightly off topic. We at Fedex are recent to using E Jepps, ala, JeppFD-Pro. We were/are using a different Jepp product (I don't know the product name) on our installed EFB's (PC based) in our aircraft but are using the JeppFD-Pro on an I pad.
A couple of observations: the I pad does a tremendous job of making the plates visible even in strong sunlight, something our older units are pretty **** poor at. From my vantage point, the JeppFD is good for domestic US operations, international, not so much.
Good access on airports without a lot of plates; so so on big airports with way too many SIDS, STARS, grounds charts, etc, etc. Organization , electronically needs work, so you can get what you want, when you want without too much rooting around. For international if you need info on the region or country your flying to... forget about it. Way too difficult to figure where or how to find what you need in a timely manner. Just hope your employer has developed a good "in house" site with the info you need.
If any intl flyers disagree, please follow up with your observations, maybe I'll learn something about navigating around this program!

I'm surprised I haven't seen anyone mention Garmin Pilot on the iPad.

I think its a very good app (with a few minor annoyances).

Have you tried it?

I have been using ForeFlight for the last year and I love it. Its great for everything I've had to do in VFR and IFR. I've just downloaded a free trial of Garmin Pilot, so far I have enjoyed it. Seems like they all do about the same thing, Foreflight is constantly growing and adding new features and Im sure the same can be said with any other app. I think it just depends on user preference.
