Interstitial Journal App

Capture the moments between tasks — type or speak a quick, timestamped note. Private by design: your iCloud, no login, no subscription.

Capture the moments between tasks.

Interstitial Journal is a small, private notebook for the gaps in your day — before you start, when you switch, when you get stuck, when you finish. Type a line or speak it; it's timestamped automatically and it's entirely yours.

THE IDEA The transitions between tasks are where focus leaks away. A quick note — what you just did, what's next, how you feel — helps you land in the next thing instead of carrying the last one with you. Interstitial Journal makes that note effortless.

HOW IT WORKS

• Open a blank note and write a line, or tap the keyboard mic and say it
• Add a tag, and optionally how you're feeling
• There's no Save button — it's kept the moment you're done
• Your day reads back as a running timeline, newest first

WHAT'S INSIDE

• Type or speak (system dictation to text; no audio is stored)
• Automatic timestamps on every entry
• Editable tags — five to start (Work, Personal, Idea, Mood, Health); rename, recolor, reorder, or add your own
• Start a task to see it live on your Lock Screen, Dynamic Island, widgets, and the Mac menu bar; finishing logs the time
• On-device insights: entries per day, focus time, and patterns by tag and mood
• Export everything to JSON or Markdown anytime

PRIVATE BY DESIGN

• No account and no subscription
• Your entries live in your own iCloud (a private CloudKit database) and on your devices
• There's no server we control and nothing we can read
• Turn on Apple's Advanced Data Protection for full end-to-end encryption

A NOTE ON THE SCIENCE Built on research into attention, reflection, and habit. Interstitial journaling itself hasn't been formally trialed, and this app is for reflection, not treatment.

Requires iPhone or iPad on iOS 17 or later.
