The B4UFLY app provides model aircraft users with situational awareness and considers the user’s current or planned location in relation to operational restrictions to derive a specific status indicator. The color and shape coded status indicators inform the user if model aircraft operation is prohibited, requires the user to take certain actions, or if there are no FAA operating restrictions other than flying safely. All model aircraft operations must always yield the right-of-way to manned aircraft.

Key features include:
- Heads-Up Status View for quick “at-a-glance” review of current status
- Map Interface to plot nearby flight restrictions
- Planner Mode - an advanced user feature to “plan” for different flight locations and times
- More Info - helpful links for using the B4UFLY app and additional FAA resources

Slow, doesn’t update properly.

I tried using this and it is incredible that ANYBODY would EVER suggest it.
Open it up, right away tells me what I already know. I’m within 5 mi of an airport, click list of already I’m smarter than this app.
Exactly what I expected from a govt app. Nearly useless except to tell you that your breaking the law.
Open up planning. Click to put an address in, hit return and select a date. Try to continue and....nothing.....or even better, a blank map that doesn’t let you do anything....since the app must be doing something let’s say it’s relaying your position to the faa so they can find you and probably have now infected your phone making in impossible to remove

Better but still bug-ridden, crashes under IOS 11

Crashes under IOS 11. Come on FAA you’ve only known IOS release coming for 6 months.
Maps still take forever to load. Do the developers realize that most often used when out at flight location where there is no WIFI?
Initial warning screen doesn’t do anything to help avoid flying near emergency services. UAV pilots want to avoid endangering fire fighters but unless app can provide some indication that something is happening near the flight’s location what good is it? If I can get a pop up alarm when I walk into a store that something is on sale, why can’t FAA work with Google to get pop up on Google maps?
Still shows 5 nm radius for any hospital that has an emergency room with a helipad. Don’t helicopters take off and land vertically? Hospital phone numbers for notifications are often wrong or go to facilities department answering machine. This is bureaucracy over activities that enhance safety.

If FAA can’t get funding to develop and maintain a usable app then team with the commercial app builders such as AIRMAP or Kittyhawk.

FOD for your phone

Super basic flight planning and info, but most of the 3rd party UAS apps put it to shame! The number of awful reviews speak for themselves and I’m not going to be a broken record and say what’s already been said, so I’ll talk about something new. Since this is THE official FAA app, I really feel the icon should NOT resemble one of those ridiculously lame “Now That’s What I Call Music” album covers. You know how many times I accidentally passed this up in the App Store bc of that?! Please FAA, study the competition, scrap this app, redesign it, work out the bugs, and update ASAP. And for the love of the Wrights, spell out “Before You Fly” and make the icon look legit for fs.
