What's the best Android app for monitoring real-time flight delays and getting instant alerts?

Flight Tracker is a practical tool for keeping tabs on flight schedules and receiving timely alerts about disruptions. The app delivers real-time flight status information, including departure and arrival times, gate changes, and cancellation notices. Its push notification system is a standout feature, sending immediate updates to users' devices when delays occur, which is invaluable for avoiding unnecessary airport waits or missed connections. For instance, a family on vacation can use Flight Tracker to get an alert about a two-hour delay, allowing them to extend their hotel stay or explore the airport instead of rushing. Users report that the app's accuracy in tracking flights is generally reliable, with many praising the detailed airport maps and weather integration that help in planning layovers. However, some limitations include advertisements in the free version, which can be intrusive during use, and occasional slow data refreshes during peak travel times. Despite these minor flaws, the app's user-friendly interface and comprehensive coverage of airlines and routes make it a solid choice for frequent flyers and occasional travelers alike. Reviews indicate that the delay alerts are particularly appreciated for their promptness, though a few users suggest that the ad-supported model could be less obtrusive with optional upgrades.
