I can confirm the app to be a rip off. In a moment of careless prosperity, I downloaded the app.
So far NONE of the jobs have existed. One employer asked where I got the info since the job had gone over 6 months previously.
Looks to me like Colm finds these jobs in the same places we all look too. Much of the info is out of date.
It also appears they have no aviation knowledge at all since the best laugh I've had was the F-16 instructor job.
I have emailed for a refund and will let you know how I get on.
DO NOT DOWNLOAD THE APP
