C Calendar app for iPhone and iPad

Initially, I developed C Calendar for my own use. Not until recently did my friends find out I was using a cool app that they never heard about. They kidnapped me and urged me to put it at App Store so they can use it too. So, here you go C Calendar.

Ive used many great calendar apps (Google Calendar, Outlook, Fantastical, Calendars, Tiny Calendar, Sunrise, Timepage, etc.) but none of them meet my needs—Im a hopeless productivity freak. So I thought, why dont I develop one for myself? Now Ive been using C Calendar for more than a year, and it saved me every day.

Whats good about C Calendar?

• One tap only
Try current calendar apps at App Store, and youll find out they always ask you to tap here, here, and here to just complete a simple task such as adding an event. C Calendar only asks you to tap once—one tap and youre done.

• I-want-it-all bird view
Many calendar apps have a bird view (monthly view) where events are displayed as a dot or a bar, but you cannot see its content directly—youve to tap into the event and jump to a different view to see it. C Calendar shows content, status, and highlight all on its bird view—you want it all, now you have it all at a single glance.

• Categorize and highlight
Usually, calendar apps dont allow you to categorize and highlight events or make it a complex process to complete. C Calendar allows categorizing events with just one tap. You can use different colors to categorize events and bold to highlight them. I like to use bold to highlight important events, white for class, blue for work, green for life, yellow for side project, purple for trip, and red for deadline/priority. I use strikethrough to indicate an event is completed and struck out.

• Notebook
C Calendar has a notebook attached to each event. You can write "Tech Meeting" as an event title and pen down details in the notebook.

• Enhanced keyboard
When you edit notebook, an enhanced keyboard will pop up. It has a handy toolbar that lists frequently-used punctuations and numbers. So you dont have to switch between letters and punctuations back and forth anymore. This significantly enhances your typing speed.

• Font size adjustment
You can adjust font size for the pleasure your eyes.

• Good design
Font type, font size, line spacing, kerning, color, icon, layout, and the whole flow are polished to ensure its a good design.

• Principle
All the functions of C Calendar are straightforward to use. You dont need to switch between views back and forth, or tap relentlessly. One tap only. Thats the principle of C Calendar.
