Since you have an Android tablet I'm going to assume you're not locked into the Apple world. Do you have a Windows setup at home? Download the Windows version here. You can do your planning, creattion of flight plans, and custom waypoints on your home system and then sync them to your tablet (or vice versa). It should also sync sketches, but that part is apparently not working. It would be nice if they'd sync aircraft profiles, but they don't. And lastly, it will not sync instrument layouts between dissimilar devices (home PC/laptop vs tablet).
On your home system, assuming you have fast internet, you may also want to load all the data for the whole US, vs. a subset of just what you need locally on your tablet. This will save a lot of space on your tablet, as well as time spent downloading the updates every so often. You might also want to use your home system to do simulation flying of a flight plan you've mapped out: Menu | About | Start Simulation Mode. Nice for seeing how the 3D EFIS looks and works.
Assuming you don't have GPS receiver hooked to your home system (though you could), you will receive a continually flashing No GPS Position Lock warning on your screen every time you start up. You can click on that and disable it. If you don't have a GPS receiver hooked up: to place your aircraft at a particular location (e.g. your home airport), and have iFly start up with the aircraft there each time, you'll want to (once) go into Flight Plan and enter a one (or more) waypoint flight plan starting at wherever you want the aircraft to be, then Close out of that screen. [My home airport is KAWO. I just enter KAWO as the start of a flight plan then close the Flight Plan screen -- entering no other waypoints.] iFly will place your aircraft at the beginning of the flight plan (which it always does for a newly created or loaded plan) and it will center the map there. You can then delete your flight plan. If ever your aircraft ends up placed at some other spot, you can do this trick again, or open any saved flight plan that happens to start where you want your aircraft to be. [You could just save your one-waypoint flight plan as your first plan in the list by giving it a name that makes it sort to the top.]
You will also not be able to see what traffic looks like, unless you hook an ADS-B In unit to your home system and have a good location for the antennas (I'm assuming both a 1090 MHz and 978 MHz antenna). Even then, most of the traffic you see will be airliners transmitting on 1090 (since they're high and therefore in view more). You will see smaller aircraft transmitting on 1090 or 978 if they're closer by. You will not see non-ADS-B aircraft unless your home is pretty close to an ADS-B ground tower *and* there's an aircraft within 15 NM of you that's transmitting ADS-B Out (triggering the ground station) *and* you're receiving the same frequencies as that aircraft.
Have fun.
