While I love that availbility of a solid EFBs like iFly GPS on Android, it seems to me that it still lags compared to EFBs of smaller companies like FlyQ.  I absolutely hate Apple and their ecosystem, but somedays I am tempted to buy an iPad/used iPhone so I can get the additional features that the other EFBs seem to have or update quickly. My wish list: 
-Higher resolution Geo-Referenced Charts/Document Legends
-Better weather breifings/analysis/outlook.  I mean look at Foreflight/FlyQ for comparison 
-PIREPS - Pretty much everyone else has this
-MAP Layers - ability to turn on google map type layering
-All in one location documents for various FAA pubs, etc.. - I have FltPlnGo for my documentation right now.  Other EFBs have this integrated
-Export Flight plans to non iFly Users
-Weight and Balance Calculator 
-Navlog - with export features
 
Adding more to the list. 
-Multi-tasking support - allow the app to run in the background when you exit it
