Shifter is an app designed for shift workers and people who need to organize their day-to-day basis to avoid missing any appointments. With Shifter, users can create fully configurable shifts, add their workday, and keep track of their schedules. The app allows users to enter their income, overtime, and early exit, set up earnings, and control working time easily. Users can also create alarms associated with each shift and customize its sound. Shifter also includes actions at the beginning or end of the schedule of each shift, such as WIFI, sound mode, and Bluetooth.

In addition to shifts, Shifter also allows users to create notes on each day and add reminders with alarms. Users can customize the sound of alarms and include images and handmade drawings in their notes. The app also offers widgets that users can create for their desktop to view their calendar without opening the app. Users can choose between weekly and monthly widgets and select the size they prefer.

Shifter's top functions include the monthly and annual view, which allows users to see all months of the year just by sliding the screen, as well as annual statistics. Users can export their calendar to Google calendar, add national holidays directly from Google Calendar, and control working time and earnings by selecting a range of dates in the Statistics section. The app also allows users to view upcoming notes at a glance, compare different calendars, share their calendar with friends via WhatsApp, email, or Telegram, create backups easily, and set up to ten different calendars.
