For some reason I have only just discovered this app. It's a bit pricey for what you get, but it could be worth the price with some improvements. If I may...
The UI behaves great and is super fast on my iPhone 5S, but the icons are so are that I have to scroll through quite a lot if I add all the flights I want to track. Could this not be displayed as a list instead? Or perhaps a toggle option for switching back and forth between displays?
While I realize this app is mainly for travellers, as an aviation enthusiast I would like to be able to use the app to get notifications for recurring flights. Having to enter flight numbers each day I'm out spotting at the airport is a huge pain, so adding the ability to make a flight recurring would be a massive benefit to me.
Lastly, the individual flight pages are brilliant and logically designed so only the most important data is shown without the need to scroll, but I wonder if it would be possible to add one piece of information: aircraft registration. It seems to be the only piece of data missing from the page.
With all these suggestions implemented, I'd be happy to recommend this app to my friends at its current selling price. Without them, I'd have to think twice because the features just aren't quite up to snuff from an aviation spotter point of view.
Glad you like the app. Sadly I think you have identified that it is for travellers and for a good app to remain that way we have to keep the focus on what it was designed to do.
I think you would be better suited to using Plane Finder with alerts?
