Since I was a kid, I’ve always loved looking up a the sky, wondering where the planes are headed towards. It’s just, there is something magical about spotting a plane and letting my imagination go wild, guessing where planes are coming from, trying to guess what model a plane is. That’s why I made Zephy. It’s a little app for people (like me) who just can’t stop watching the skies above. So, what can Zephy do? With Zephy, you can do more than just look. You can see what aircraft are flying above you with the radar, filter them by distance, altitude, direction, or only show the aircrafts that are in the air. You can even track a specific aircraft and see where it came from, where it’s going, and get directional input with the built-in compass. Or, if you’re feeling lazy, just use the “Track Closest Plane” button and Zephy will pick the nearest one for you. And now for the million dollar question. Why Zephy? I made it to be simple, personal, and clutter-free. No overwhelming data, no feeling like you’re in a crowded control tower. Just an app for people, who (like me) can’t resist looking up and seeing what’s flying above them. And if there are clouds in the way, you can always use the radar to find where the planes are.
