What DayHeart does
Turn on only what you need — the rest stays out of the way.
Calendar and Today
Month, week and day: shifts, tasks and events side by side. It always opens to today.
Shifts and classes
Pick a shift and tap the days — your schedule is ready. Hours and earnings add up automatically, and homework stays with each class.
Tasks and groups
Write it down and let it go. Shared task groups with friends and an urgent–important matrix.
Habits
Mark them with one tap. A missed day never resets your streak.
Mood
Mood, sleep and energy in a few seconds. A weekly summary and a PDF report.
People and dates
Birthdays with reminders in Telegram, notes about your people and a countdown to important dates.

Your data
Your entries live on your device and, once you sign in, in your account too — so they are on all your devices.
Mood entries can be encrypted — then even we cannot read them. The key is made from your 12-word recovery code; neither the code nor the key ever reaches our servers.
No ads. We do not sell data or pass your entries to outsiders.
