Formerly great, now unusable

This used to be such a great app! Unfortunately its gone downhill so much that its nearly unusable. Two main gripes:
1- it syncs all the time with a black screen of doom. You have to wait an indeterminable amount of time for it to finish syncing before you can even see your list again.
2- on an iPhone 5 the resolution was fine. On a 6S, its horribly bloated.
