You need a not-so-old Android phone to run the app. My HTC Desire (not HD, yes, I know that's years old now), even with a re-partition to give more phone data space, starts running out of space rapidly once the app is running and downloading data. In other words the devs didn't think it would be a good idea to have the downloaded data go on the SD card (where I have lots of space free).

The app itself installs fine, it's just that huge data grab to 'system data' space that brings my phone to its knees.
