About this app

Diaro: Journal Heatmap is a personal diary app built for people who want to build a consistent writing habit and see their progress at a glance.

Every day you write an entry, your streak grows. The heatmap calendar gives you a clear visual record of how consistently you have been journaling — showing which days you wrote and how your habit has evolved over weeks and months.

There is no account to create and no server involved. Everything you write stays on your device. Open the app, write your thoughts, and close it. That is all there is to it.

Key features:
- Daily journal entries with a clean writing interface
- Heatmap calendar to visualize writing frequency over time
- Streak tracking to keep your habit going
- Onboarding flow for new users
- Fully offline, no registration required
- All data stored locally on the device

Whether you use it as a reflective diary, a quick daily log, or a habit tracker, Diaro gives you a simple and honest view of your writing consistency without distractions.
