genaro:
It was a rhetorical question. I wondered if you could answer your own question, after all we all have different needs.
If you said '3-4 out of 5' out of consideration for not oversharing with the internet then I applaud you, but I really don't believe that your emotional state can be expressed on a one dimensional scale in 5 increments of 20% between good and bad, however you define those two scoundrels.
So yes, if you can't remember and have to guess then an app may help you (or you could use the back of an envelope and a ball point pen). Diaries I think have the benefit of providing data for future reference, should it become useful, but you don't need to re-read (overanalyse) them every day.
So the question behind my question was 'what would you hope to gain by recording your (not really one-dimesional) emtional state?', and that's also rhetorical, I don't actually want to possess this info.
Besides, if there was such an App then someome somewhere would wait till you were feeling really good and then hit you with adverts for shit they want to sell you.
Thanks for clarifying. I figured there was some 'question behind the question', but I didn't want to assume to know what that question was.
There are plenty of such apps available. I am usually hesitant to make assumptions like that all apps are solely money-driven and predatory, just because I'm not convinced that way of thinking is what's best for my own mental health. After all, DhO is an app, of sorts. So is Reddit.
But then again, the one I downloaded just hit me with a 'Free Trial Expired' message so I guess the joke is on me
