What Dayleaf does

Dayleaf is a one-line-a-day journal designed for real life. Open the app, see today's gentle prompt, write a single sentence, and you're done. No paragraphs, no guilt, no blank pages — just a tiny daily habit that adds up to something beautiful.

Every entry becomes a leaf in your Year Grid: a full calendar view where each day is shaded by mood, so you can see at a glance which weeks felt warm, which felt muted, and where the turning points were. Tap any leaf to read what you wrote, then scroll to On This Day to rediscover entries from the same date in past years — a quiet, delightful form of memory that longer journals rarely surface.

Built entirely on-device with SwiftData. No account, no subscription, no internet connection ever required.

• Daily prompt with one-line entry and mood picker (1–5) • Year Grid view: 365 mood-colored leaves at a glance • On This Day: past entries resurfaced on each calendar date • Streak counter and gentle daily reminder • Mood Insights: monthly mood rhythm charts • 100% offline, Face ID lock, no account needed

What's inside

Today's Leaf — A focused home screen showing the date, a rotating daily prompt, a single-line text field, and a five-point mood picker. After saving, the entry is sealed for the day with a gentle animation.
Year Grid — A full 12-month calendar grid where every past day is rendered as a small rounded rectangle (leaf) tinted by mood — from warm amber (high) to cool slate (low) with white for empty days. Tap any leaf to read its entry in EntryDetailView.
On This Day — Each morning the app surfaces any entries written on the same calendar date in previous years, presented as layered cards with the year prominently displayed — a moment of personal time-travel before the user writes today's line.
Mood Insights — A monthly bar chart showing average mood per week, a running streak display, and a simple heatmap of the best and hardest days — enough signal to spot rhythms without becoming a clinical dashboard.

Why we built it

Most people who want to journal never stick with it because the blank page is overwhelming and the time commitment feels too large. Existing journal apps either demand lengthy entries, require an account, or bury memories so deeply they are never revisited — killing the motivation loop.

What makes it different

Dayleaf uniquely combines a hard one-line constraint with a visual Year Grid (mood-colored leaf per day) and an On This Day memory resurfacing engine — a triumvirate no single competitor offers fully offline and free of subscription. The leaf aesthetic and the sustainable micro-habit format set it apart from wordy jou…
