I've used iMoodJournal for the past 7 years and I love it. It's a simple 1-10 colored scale for overall wellbeing. Then I add tags for whatever I feel I want to track for that particular day like #weather_rainy (I have SAD too), #sleep_9hrs, #activity_none, #anxiety_10. It prompts me as often as I want throughout the day. It takes all of 30 seconds to enter.
It then let's you export the data to something like Excel to make pretty charts of your ratings so you can see any corellations.

When Grey was talking about the bot that would text Brady asking how he was feeling I got the stupidest smile on my face.
It's already a thing I use XD
