About this site
We make free calculators, plain guides and printables for habits, food, sleep and water. They lead to the Daily Journal, a private app for habits, food, mood and sleep that is free to start.
What we believe
Tools should show their working, say what they cannot do and never ask for more than they need. Every calculator shows its formula and sources, and nothing you type into them is saved.
The app
The Daily Journal keeps your habits, food, mood and sleep in one private place. It is free to start: sign up and your account opens straight away. The app is built so that what you write in it stays yours.
Who is behind it
The Daily Journal team. You can reach us from the contact page.
How we keep it honest
We follow the rules on the how we calculate and sources pages, and we state our limits on the health disclaimer.
