Zen Pump is a $2.99 iOS app designed to pump you up against “any challenge.” The first portion is recorded voice calls from Coaches to rally your spirits.
However, I think the second portion of the app, the daily mood diary, is much more interesting—it has quick entry with several keywords, mostly moods, and an overall rating for the day, and/or you can fill in more detailed notes.
I found using the diary to be quite simple and streamlined, and already one of the better mood diary tools. It makes me wonder how this app will evolve over time.
