Looking for an ADS-B Exchange alternative on iPhone?

If you use an unfiltered ADS-B map because you care about military and unusual traffic, Squawk is an iPhone flight tracker built for the same reason — with alerts that reach your Lock Screen when something worth seeing comes near.

What Squawk gives you

• Military never filtered out. If a military aircraft is broadcasting, it's on Squawk's map at every zoom, drawn with its real silhouette, with a one-tap military-only mode.
• Alerts with the app closed. Squawk watches an area around you and pushes a notification when military or widebody aircraft come near — the alert engine runs on our server, so it works when the app isn't open. One alert area is free.
• Base movements and type takeoffs (Pro). Get pushed when aircraft depart or recover at 230+ watched military bases, or the moment any aircraft of a type you pick — a B-52, a U-2 — gets airborne.
• Emergency squawks worldwide. 7700, 7600 and 7500 pulse on the map, and Pro can push them to you.
• Area replay. Rewind any region and watch every flight again — 24 hours free, 30 days with Pro.
• No ads. Not in the free version, not in Pro, not ever.

Where the data comes from

Squawk is built on community ADS-B receiver networks, shared as open data, with public credit and a no-resale pledge. If a transponder broadcasts and a volunteer receiver hears it, it shows up.

Price

Free to download, with the full live map, military layer, trails, 24-hour replay and one alert area that pushes. Pro is $4.99/month or $34.99/year; the yearly plan starts with a 1-week free trial.
