About this app

Daylum Journal Heatmap is a personal journaling app built around one idea: consistency matters. Every entry you write gets recorded and reflected on a color-coded calendar heatmap, letting you see at a glance how regularly you have been writing over days, weeks, and months.

There is no account to create, no server sending your words anywhere. Everything stays on your device. Open the app, write what is on your mind, and close it. That is the whole flow.

The heatmap view gives your journaling habit a visual shape. Days with entries glow with color intensity based on how much you wrote. Gaps stand out. Streaks feel satisfying. Over time the calendar becomes a kind of personal record you can look back on without reading a single word.

Each entry supports free-form text. You can browse past entries by date, scroll through months, and revisit what you were thinking on any given day. The interface stays out of the way so writing feels natural rather than structured.

Daylum suits people who want a private writing habit without complexity. No prompts, no categories, no mood tracking unless you want it. Just words, dates, and the visual story of how often you showed up.
