Mental Notes Daily Journal is a private, beautiful place to write. Open it, pick up the pen, and let the page do the rest. Everything you write stays on your device. There are no accounts, no cloud sync and no tracking. Your journal is yours alone. Your Desk greets you each day with a fresh writing prompt, your current streak, your daily word goal, and an "On this day" look back at pages from earlier years. Write on a paper-style sheet with binding holes and margin rules. Your work autosaves as you type, so you never lose a thought. Tag your mood on a scale from Stormy to Radiant, star favorites, and add tags to keep things organized. Search the Archive to find any page by title, words, tags or prompt. The Calendar shows a heatmap of your writing habit and the mood weather of each day, so you can see patterns over time. Make it feel like yours. Choose Paper (light) or Ink (dark), or match Windows. Pick your typeface and text size, and set a daily word goal. When you want a copy of your writing, export it to Markdown or take a full JSON backup at any time. Mental Notes Daily Journal is made by Mobile Logic.
