DayHeart is a day planner: shifts with pay, study and a shared group timetable, mood and habits — in one calendar on all your devices.

Your day in one place. Classes in the morning, a café shift in the afternoon, homework in the evening: DayHeart shows the whole day together and reminds you of each thing on time. Turn on only the sections you need; the rest stays out of the way.

Shift schedule and pay
— Build your shift schedule in a few taps: pick a saved shift and tap the days. Repeats: 2 on / 2 off, 5/2, daily or weekly.
— Hours and earnings for the day, month and year add up automatically, including breaks, night shifts, extra pay and bonuses.
— Several jobs, each with its own shifts, rates and totals.
— Shift alarm: set a wake-up time in a saved shift, and the phone rings a real alarm on your shift days.
— Print your shift schedule or export a month of shifts to Excel.

Class timetable and study
— A class timetable with rooms and links to online lectures; odd and even weeks.
— Classes from a photo: take a picture or a screenshot, or add a PDF or Word file. DayHeart reads the classes, you check them and add them for the whole term.
— Homework right inside the class, with a reminder; exams with a countdown and topics you tick off as learned.
— A shared group timetable: the class rep sends one link to the group chat, and everyone (up to 50 people) gets the same timetable. When a class moves, it moves for everyone, and Telegram lets you know.

Tasks, habits, mood
— Tasks: quick capture, an urgent–important matrix, shared task groups with friends.
— Habits: one tap to mark; a missed day never resets your streak.
— Mood, sleep and energy in a few seconds: a calendar of faces and a weekly summary.
— People and dates: birthdays with reminders, countdowns to the dates that matter.
— If you want them: shared shopping lists, expenses and budgets.

Friends
— Share your shifts, events or mood, with each friend just what you choose. Your earnings and notes stay private.

On all your devices
— Home screen widgets: Today, Up next, Habits, Friend and Friends.
— Reminders arrive on time, even offline.
— Lock the app with a code or your fingerprint.
— Sign in with Telegram or Google to see the same entries on your phone, in the browser and in the Windows app. Works offline too.

You can start without signing in — your entries stay on your phone. 24 languages, including Russian and Ukrainian.

Core features are free. We never sell your data, and you stay in control: export a copy of your entries or delete your account with everything in it from Settings.
