About this app

Simple Calendar is a free calendar app, schedule planner and organizer for work, family, school and everything in between. Plan your day, set reminders and manage your tasks in a clean, easy timetable — with or without a Google account.

■ Scheduling made simple
One tap opens the planner: pick a time, add an event or task, write a note and set a reminder so nothing slips away. Color-coded time blocks make it easy to see when to work, study, exercise and spend time with the people you love.

■ Monthly, weekly & daily planner views
Plan a day, a week or months ahead. Switch between the monthly calendar for the big picture, the weekly planner with 7-day, 5-day or 3-day views, and the daily agenda for hour-by-hour time planning.

■ Syncs with Google Calendar — or works without it
Use the calendar on its own, no account needed — or sync with Google Calendar to keep every device up to date. Calendars from Outlook, iCloud, Exchange and Office365 can be connected too, so all your schedules live in one app.

■ Backup and device transfer
Events synced with Google Calendar appear on your new phone as soon as you sign in. Calendars stored only in the app can be saved with the built-in backup feature and restored when you switch devices.

■ Shared calendar for family, friends and team
Share your work calendar with colleagues to sync tasks, share with family so they know when you're busy, or plan dinners and workouts together with your partner. A shared schedule keeps everyone on the same page — you'll even know exactly when to pick the kids up from school.

■ Never miss a thing with reminders
Set an alarm or appointment reminder for any event. From business meetings to birthdays, your agenda tells you what's ahead — so you're always on time.

Ratings and reviews

Scheduled items have disappeared from the calendar view, leaving only colored time slots (data did not disappear, as you can still read it, but only if you click open each colored time slot to find out what is in it). I have written to the developer, with screen shots of the issue, and have not received a response. I am uninstalling and getting a better calendar app.

I was using another calendar which had a clean interface until, unexpectedly, they started charging weekly. Decided to try this one, and although I wasn't thrilled with the ad banner at the bottom, it doesn't bother me at all now. Great choice of colours, very user friendly and hey..... no cost. UPDATE well, they've made the ad banner larger and flashing like Crazy, for a COST you can get rid of it.

Great, simple, no frills calendar with many color options. Can add as many calendars as you like to it and color code them. Connects with Google calendar. 4 stars instead of 5 because I would have loved an automatic cloud storage feature, so I don't have to manually backup all the time and send the backup file to myself. If it had that feature it would have been perfect.
