Great Journaling App

Ive been using Wonderful Days almost daily for the past 18 months or so on my iPhone 4S. Ive never had a crash or any problem. The app inspired me to get back to writing for enjoyment. I like being able to e-mail specific entries as PDF. I do fear losing my past entries even though Ive not had any problems. Id be crushed if that happened!
PS: I just successfully uploaded all 350 entries to Evernote Premium. Now I feel better! However, this preserves my words but not the formatting. Id like to be able to save my journal in original format. Id also appreciate folders & tags.
