Only for iPhone
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
iPhone
Untangle the thought that keeps looping in 6 calm steps: write it down, weigh it, find a balanced view. Mood logging is free and unlimited. Encrypted on your device.
Stuck on a thought that won't let go? Thoughtline walks you through the thought record, a core cognitive behavioral therapy (CBT) technique, one gentle step at a time.
Name the feeling, weigh the thought, find a more balanced view — in a few minutes.
What you write is encrypted on your device; no one else can read it.
THOUGHT RECORD IN 6 STEPS
Describe the situation, catch the automatic thought, pick your emotions and their intensity. Weigh the evidence for and against, then land on a balanced thought. Re-rate how you feel at the end and see what shifted.
MOOD JOURNAL
Log your mood in seconds. A trend chart and emotion breakdown help you notice patterns — in calm, non-judgmental language.
ACTIVITY PLANNING
Use behavioral activation to plan small steps that lift your mood; rate enjoyment and achievement to learn what actually helps.
BRING IT TO THERAPY (Pro)
Turn entries from any date range into a clean PDF report for your therapist. The report is created on your device and never uploaded.
PARTNER WIDGET
Share just your current mood with someone you love, right on their Home Screen. Your writing is never shared, and you can pause sharing anytime.
PRIVATE BY DESIGN
• Free-text entries are encrypted on your device

SUPPORT IN HARD MOMENTS
If your writing suggests you're going through something difficult, Thoughtline shows support lines near you.
