I wonder what the reason behind this action is ? Is the money paid to FR24 a 'forever' fee, or a yearly fee ? If a load of work has gone into the new app, then that must have taken some effort by coders/programmers etc and i'm sure that FR24 would like to recoup those costs. I use it for free (with restrictions), so for all the people like me, they get nothing aside from recommendations. I have paid for two other trackers in case you are wondering. I'm not sure just how profitable these tracking apps are for the developers, as the number of enthusiasts must be quite small in comparison to most app's subscribers in the online universe.
