Notice what you feel and why.

A thought and emotion diary based on cognitive behavioural therapy. An entry takes 2–5 minutes, and you see what repeats and what changes.

Coming soon to the App StoreiPhone and iPad
Musing on iPad: entries by day with details
Musing on iPhone: home screen

An entry in a couple of minutes

Situation, emotions rated 0–10, automatic thoughts and body sensations. Three methods to choose from.

See what changes

An alternative thought and re-rating, “before → after” arrows, statistics and a PDF report for your therapist.

Yours only

Entries are encrypted on your phone and protected with a PIN or Face ID. No ads, no trackers, no AI reading your entries.

Calm down

Calming sounds with a timer — rain, sea, forest — keep playing with the screen off. Breathing exercises: box breathing, 4-7-8, even breathing and long exhale.

For therapists

Coming soon: a client will be able to connect you to their diary, so you can see their progress between sessions. Write to us if you would like early access: igoist@me.com

Musing is a self-observation diary. It is not a medical device, does not diagnose and does not replace professional help. If you are in crisis, contact your local emergency number.
