Poor web portal, outdated app

Long-time user. Was a great app but the web portal is slow, buggy, often useless (edit: web portal unusable for weeks now and zero developer support/response). IOS app has not been update for ages to support iPhone6 or 6s (and so looks zoomed in / old). Not recommended anymore - searching for a replacement.

EDIT 20Jan2016: Migrating to Wunderlist for all lists and Paprika for groceries. Sadly NO apparent way to export from Grocery Gadgets. No developer support. App not updated since IOS7. Do NOT buy this app!
