This is very frustrating - I'm very late to this party!

I paid for FlightTrack Pro on both iOS and on Android (when I switched). I didn't "upgrade" to FlightTrack 5 because the TripIt integration is simply unbeatable for me. Anyone who uses Concur for corporate travel, or has email integration turned on will understand. All I had to do was book a flight and bam, it's on my phone being tracked months in advance.

I signed up for a free 7-day trial of FlightRadar24 Silver, and was disappointed to find that you can only set an alert for a flight a few days in advance (much like Kayak Pro). I also wasn't impressed to find that despite being supported across multiple platforms, if you create an alert on the web it comes in via email vs. push if you create it on a mobile app.

Anyhow - I notice a lot of you are iOS users. Android users who can't live without TripIt - what did you decide on?

EDIT: App in the Air does look nice - but the subscription breakdown isn't very clear. Lifetime subscription is $49.99 in the Android App (US).
