iPad app clumsy and seems to freeze

the iOS (iPad) app is clumsy and seems not to work right. It is clumsy, it misleads me, and it freezes at times. I would like it to do it all the same as the web site.

I am new to this forum. I’ve been using flightaware for alerts for a few years.

Which model iPad, version of iOS, and FlightAware app?

I think it’s an iPad 2. It’s iOS 9.2.1 and flightaware app “current”.

I know not how to find version ID. I try to keep all apps current.
