  • Don't wait for a disaster

    We avoid making big changes in our lives, staying in abusive relationships or jobs we hate because we’re terrified of uncertainty.

App Store Reviews

Excellent tool, infinitely customisable This is a great App. I’ve been meaning to get into the habit of journaling for years and never been able to keep it going. The gentle ‘How are you?’ reminders have had the added bonus of bringing me back to the present a few times when I really needed to reflect on what was going on. I love the customisable hashtags for tracking what is important to me, and found the visual display of what I had been tracking suprisingly moving.
