Buggy

Designed only for iPhones not iPads

When using the iPhone app on my iPad, very buggy when streaming to the point that I gave up and used my iPhone which worked only slightly better.

Streaming photos only works for some photos and others are "not supported"

When streaming a video, it only streamed 10 seconds before crashing.

Supanatral about The Roku App (Official), v3.5.3
