Todak Aquarium Diary

One line a day is enough. Log your mood, watch your fish grow, and your aquarium fill with life. No ads, no servers — everything stays on your device.

Todak Aquarium Diary is a mood journal app where emotion tracking meets a growing aquarium. Pick how you felt today and leave a one-line note — that's all it takes.

Aquarium Healing System

As your entries accumulate, your fish grows from egg to fry to adult. Streak days and XP unlock plants, gravel, and bubble decorations, gradually enriching your aquarium.

Focus Writing Mode

Open Focus Mode and the diary screen expands to full screen. iPad and Mac get extra writing space so you can concentrate without distractions. Voice input is supported.

Today's Question

When you don't know what to write, pick one of three daily-changing questions and bring it straight into your note.

Insights

Visually analyse your mood distribution, recovery score (0–100), and emotional variability. The home screen alerts you when your recent mood flow shifts.

History

Explore entries by date, mood, or tag, and pin the important ones. Export to PDF or review your flow in calendar, weekly, or monthly views.

Fully Local Storage

Every entry stays on your device only. No server transmission, no ads, no behaviour tracking. JSON backup lets you carry your records to a new device intact.

Security

Use Face ID or Touch ID to lock the entire app, or just the History and Settings screens selectively.

Background Music

The Todak Todak OST, written and composed specifically for this app, plays gently in the background. It works even in silent mode and shows synced lyrics.
