EASY VFR 4 doesn't work properly on my iPad Mini 3 (64GB). There are still 4.13 GB of space available.
After the first error message (Your system has 970 Mb RAM ...) the program continues and when zooming in, the second error message ((DEBUG 🙂 Memory fragmentation detected, attempting to-de-frag....! ) and the app crashes (closes itself).
The iPad mini 3 and iPhone 6 are two 64 bit devices with only 1GB of RAM. We are currently experimenting to see if we can lower the 2GB RAM requirement so these two devices can run EasyVFR4 also, but to be honest its not easy, and I'm not sure if it will ever be possible, sorry.
