I had been away for a while, loved the app and suggested it to everyone, but I come back and it is taking 20 to 30 seconds for each change I make such as adding or deleting foods, it just hangs for half a minute. Is this a glitch for today, or is this permanent?

Hello,

Try clearing out the cache for the app.

* Double tap the home button to bring up the Recents List
* Tap and hold any icon until they wiggle
* Press the red to delete the desired app from this list.
* Press the home twice button when done.

Sorry, I am old school. I was having those difficulties on my home computer, not a mobile device. Seems to be running faster today.
Thanks for the quick reply.
