Skyby vs Underplane

Know exactly what's flying over you. Look up, and whatever is overhead appears on screen. Airliners, private jets, helicopters, and more, identified instantly. No searching, no typing, no menus. NOTE: Some features shown in the screenshots require Skyby Pro. Whether you're a planespotter camped at the end of a runway or a casual fan glancing up from home, Skyby reads the sky in real time and shows the aircraft directly above: the airline or operator, the aircraft type, the altitude, and, for scheduled flights, where it came from and where it's headed. An inbound indicator shows when a flight is coming into range. Two ways to use it: Set it and forget it. Prop Skyby on a desk, shelf, or windowsill and leave it running: a quiet radar for your patch of sky. Set an alert for the aircraft you care about, and Skyby chimes the moment one flies over. Pull it out and look up. On a walk or in the backyard, open Skyby and see what's flying over right now. From airliners to helicopters: Skyby identifies it all. The passenger and cargo jets, the private planes and business jets, the helicopters overhead. And yes, if a blimp drifts over, Skyby catches that too. Prefer to keep it to the airlines? Flip on Commercial Only in settings. Set your spot, or take it with you: Use your current location Drop a pin anywhere in the coverage area to watch the planes over home while you're away Or set the pin to live, and Skyby follows you as you move WHAT YOU GET Instant overhead ID for the aircraft above you Adjustable search area, up to 3 nm free (wider with Pro) Alerts that chime when a plane you care about flies over (A380 and 747 built in, free) An inbound indicator when a flight is coming into range Real routes and aircraft types for scheduled flights A logbook that saves your catches automatically Available across the US, Canada, UK, Europe, Australia/New Zealand, Japan, Korea, Mexico, Philippines and Singapore today, with more on the way Skyby Pro adds aircraft photos matched to the tail number (when available), custom alerts (any airline, aircraft type, flight number, or tail), your full logbook with search and bookmarks, detailed stats, and an even wider search radius.

Planes pass over you all day. Underplane tells you which ones — and exactly where to stand. It reads live flight data, projects each aircraft's track forward, and finds the ones heading your way. Most of the time you don't need to move at all: if a flight path already passes close to where you are, Underplane just tells you to stay put. WHEN ONE'S COMING • A countdown to the second it passes overhead • Callsign, altitude and speed, live on the map • Walking or driving directions on the rare occasions it's worth moving • A Live Activity on your lock screen, so you can put the phone away HOW CLOSE DID YOU GET Every catch is scored on how near the aircraft's path came to you: Good — within 1 km Great — within 500 m Excellent — within 100 m Perfect — within 10 m Standing in exactly the right place is the whole game. FOURTEEN ACHIEVEMENTS First Contact for your first plane. Wheels Down for one under 1,000 ft. Cruising Altitude for one above 30,000. Night Shift, Full Fleet, Bullseye — and Dead Reckoning, for five catches within ten metres. MAKE THE MAP YOURS Six map styles, all included: Monochrome, Standard, Traffic, Terrain, Satellite and Hybrid. Turn place labels on or off. Nothing here costs extra. SET YOUR OWN ODDS Choose how close a flight path has to come before Underplane calls it catchable — anywhere from 500 m to 15 km. Tight if you live under an approach, wide if planes are rare where you are. FREE AND PRO Catch three planes a week for free. Underplane Pro removes the cap and adds automatic alerts when something catchable is inbound, plus your full statistics and the people who stood under the same plane. Underplane needs your location to work out which aircraft are heading towards you and where to stand. It's used for nothing else.
