Writing down your progress is one of the most studied ways to reach a goal. Daily Journal makes it a minute a day, shows you the progress building, and lets you do it alone, with your partner, or with a group.
These are the notes inside the app's Mantra tab, each one read back against its source. Most are observational, so we say "linked to" and never "causes".
Across 138 randomised studies of nearly 20,000 people, monitoring progress helped, most of all when written down.
Used in: Tracking and ProgressWriting a plan in that form helped people reach goals, with a medium to large effect.
Used in: Plan remindersIt ranged from 18 to 254 days between people. A small study of 96 people, so be patient and expect it to vary.
Used in: streaks and best runPeople who listed things they were grateful for reported more positive feelings. Not every measure moved, so treat it as a small, cheap thing worth trying.
Used in: Thoughts of the day148 studies and about 309,000 people. The link was comparable to well-known risks such as smoking.
Used in: Together and groupsPeople with closer ties to family, friends and community were happier, healthier and lived longer. Quality matters more than the number of friends.
Used in: partner and group sharingStudies show links, not proof of cause. Nothing here is medical advice. The app holds more cards on sleep (7+ hours), steps, strength and food, each with its source.
A journal works on its own. It works better when someone you trust can see it too. You choose who, person by person, and you can stop at any time.
Your habits, food, sleep and mood in one private place. Charts show what is working.
Invite your partner with one link. See each other's streaks, send a reminder, and make a daily check in something you do together.
Plan tasks, set if-then reminders and track the habits that keep your work days steady, such as wake up, steps and focus time.
Friends, family or a team. Joining shares nothing: each person decides who sees what, and whether anyone may write in it.
Every picture below is the real app, drawn as vector, so it stays sharp. The people and numbers are demo data for a made up user called Sam.
Open the app and the charts answer the one question that keeps people going: am I getting better? Streak, days active, wake up time and exercise days, each with its own line.
Tracking is a table of your days: one coloured column per thing you track, one row per day. Gaps show up straight away, and so do the runs you are proud of. The Progress view counts it for you.
Type your coffee, tap Add, type your sandwich. The keyboard stays up. Under every box the things you wrote before come back as one tap chips, so the same breakfast takes a second.
Type what you ate and the numbers appear: calories, protein, carbs, fat and fibre for each item and for the day. Save your usual meals and recipes and add them in one tap.
Every day opens on a fresh card. Scroll for more: affirmations, quotes, science notes and book ideas. Science cards name the study and the year, and say "linked to", never "causes". Tap the heart to keep one.
Put tasks and notes on a month calendar. Set a daily reminder, once a day or every few hours, and it opens over the app until you press Continue. Invite somebody and it lands on theirs too.
Make a group of two or twenty. See everyone's streaks side by side, cheer a good week, and send a reminder when someone needs a nudge. Joining shares nothing: you choose person by person who sees your journal.
Earn XP for the days you write, the water you drink and the weeks you keep going. Badges come in bronze, silver, gold and platinum, with a few secret ones. Make the app yours with six colour themes.
What is built in today, counted from the app itself.
Screens and figures such as the 12 day streak and 1,645 kcal are demo data for a fictional user. The counts above are from the app's own code.
Plenty of apps track one thing. This one holds the whole day, backs it with named research, and lets the people you love in.
The right hand column describes what is common among single purpose apps, not a named product.
A minute to begin, a minute a day after that. Invite your partner whenever you are ready.
