Log your mood in a few seconds each day and see the pattern build into a heatmap over weeks and months — free, and tied directly to your journal entries.
EK Diary's mood tracker takes a few seconds a day: pick how you're feeling, and it gets logged next to your journal entry for that date. Over a few weeks, those daily check-ins build into a mood heatmap so you can actually see patterns — a rough week before an exam, a lift after a run — instead of relying on memory.
Because the mood log sits next to your daily entry, logging it becomes part of the same habit as writing your diary — no separate app to remember to open. Over time, that consistency is what makes the heatmap useful: gaps in a standalone mood app are common, gaps in something you already open daily are rare.
A single day's mood doesn't tell you much. A heatmap across a month does — you start noticing that Mondays are consistently harder, or that a run in the morning correlates with a better mood log that evening. That's the kind of pattern that's nearly impossible to spot without something tracking it for you.
Your mood log connects naturally to your habit tracker and your day's journal entry — so when you look back at a low-mood week in your weekly review, you can see what habits slipped and what you actually wrote about at the time, rather than piecing it together from three different apps.
Mood tracking is free with no entry limit, and your logs are encrypted and stored on Firebase (Google Cloud) — never shared, never used for ads. See the full details on our FAQ page.
A single mood entry is a data point; a heatmap is a story. Colour intensity across a month makes slow trends visible in a way daily memory can't — a string of low-energy days that quietly followed a change in sleep schedule, or a steady lift that started the same week a new habit took hold. The point isn't to chase a "green" month every month; it's to have real evidence the next time you're deciding whether a change in routine actually helped or just felt like it did in the moment.
A few seconds — pick an emoji or short label for the day. You can add more detail in your journal entry itself if you want to, but the mood log alone is deliberately fast.
Yes, the heatmap view shows your logged moods across weeks and months so you can spot longer-term patterns, not just how today compares to yesterday.
No. Mood logs are encrypted and stored on Firebase (Google Cloud) and are never sold, shared, or used to train AI models or target ads.
