What Users Say
I've tried a dozen mood trackers but MoodLog is the only one that actually shows me my patterns. The heatmap alone is worth it — I can see my rough weeks at a glance and it's helped me talk to my therapist more effectively.
— Sarah K., Wellness Coach
The fact that the AI insights run entirely on my phone is a game changer. I don't have to worry about my private thoughts being sent to some server. Finally a journal app I actually trust.
— James L., Software Engineer
The home widget makes it so easy to log quickly — I do it right after morning coffee. Three months in and I've never been this consistent with a habit app.
