## What is Cal2Todo?

-Your EVENTS now appear as your TASKS.
-You will never forget your appointments using this app.
-You can push tasks back later.
-It has an Intuitive design allowing you to quickly look at the day's agenda.
-You can use Google calendar as well, if your built-in calendar is synced with Google calendar.

Who will benefit most from this app?

-Users who usually procrastinate and sometimes forget to do things.
-Users who want to finish everything before going to bed.

Convenient 4-day view
-Fully compatible with the built-in iPhone calendar.
-You access your recent appointments by tapping the buttons at the bottom of the screen.
-Can display a count-down timer for your next appointment or event.
-Colorful screen - pick different colors for different calendars

Basic usage
-Home screen has today's agenda.
-When you finish events, you check them off. Once checked, it goes into the background.
-Items in red are overdue. Items in yellow are upcoming appointments (Less than an hour)
-Most importantly, when you realize that you do not have time to do something, hit PROCRASTINATE. Don't worry, It will come back in a couple of days!!

Items can be deffered from 15 mins to 2 weeks. These settings are fully customizable.
- Today     update the date as of today
- Tomorrow  update the date as of tomorrow
- Next week update the date as the same day next week
- Morning   update the time for the next few mornings.
- Afternoon update the time for the next few afternoons.
- Evening   update the time for the next few evenings.
- 1hr later  push back 1hr
- 3hrs later push back 3hrs
- 5hrs later push back 5hrs
- and more!

Miscellaneous
-The button on the top-left of your screen will toggle items to be visible/invisible. 
-You can edit your items on this app and the changes will appear on the original built-in calendar.
-You can delete items by swiping & tapping.
-You can select the calendar(s) of your choice.

Note:
-This calendar only focuses on the next four days (yesterday, today, tomorrow, and the day after tomorrow)
-The app retains the "Check ON/OFF" data by tagging the item with an ID. Some apps might change this ID. If that is the case, Cal2todo might not work properly.
-This app only communicates with the database when it starts, therefore, the icon badge will not be updated until you open Cal2todo.
