Vayu tracks any flight, live — no app-switching, no refreshing, no waiting. Search any flight number. Vayu finds the live ADS-B position and schedule data simultaneously, then shows you everything: departure and arrival airports, live position on an interactive map, ETA countdown, distance covered, delay status, and a Dynamic Island that keeps you updated without opening the app. WHAT IT DOES • Live flight tracking — real ADS-B position, updated every 30 seconds • Dynamic Island — see route and ETA without unlocking • Interactive map — live aircraft position on a great-circle route arc • Full stats — distance covered, departure and arrival times, delay info • Gate and terminal info — shown when available • Flight history and favourites — your most-tracked flights, one tap away • Push notifications — departure, delay, and landing alerts • Works worldwide — any airline, any route, any country HOW IT WORKS Search any flight number — BA249, EK203, QR007, whatever you need. Vayu cross-references live ADS-B radar data with scheduled flight data to build a complete picture: where the aircraft is right now, how far it has to go, what time it lands, and whether it's running late. The Dynamic Island updates live while you use your phone. The Lock Screen widget means you can check a flight in one glance. Push notifications fire when the gate closes, when your flight departs, and when it lands. NO ADS. NO PAYWALL. NO ACCOUNT. Vayu will never show you an ad. There is no premium tier. There is no free trial. It does not ask for your name, email address, or phone number. You search a flight. You track it. That's the whole thing. THE STORY I built Vayu because I was tired of refreshing a website every three minutes waiting for someone's flight to land. This is my first app — built to scratch my own itch, not to sell it. Vayu — Sanskrit for wind, air, the breath between places.

Verdict
The clearest difference is monetization model: Vayu at free against iState's paid. Vayu also leads on iOS requirement (17.0 vs 26.0). iState's advantage is ratings volume (5 vs 1). On price, rating, review sentiment and update cadence there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. iState sells 1 in-app purchase, starting at $0.99 per month and Vayu sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for iState against 5.0 for Vayu. That said, the two scores are not equally well evidenced: iState has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
iState ships an update weekly, Vayu every 5 days. The most recent releases landed on November 6, 2026 and October 31, 2026 respectively.
