Founder here. Happy to answer any questions you might have. Moodistory is a mood tracker that you can use to find out dependencies between events/activities and your mood. I'm personally using it to track my work happiness. Based on the feedback I get, I'm adding new features continuously. App is currently iOS only. Since I'm using a paid model for it, and I want to show it to you, I'm giving away 3 promo codes. Just send an email to hello@moodistory.com and I’ll reply with a promo code. I'll update this post to indicate whether there are still promo codes left. Looking forward to any comments! :)
