Short description
zerocal is an iPhone calendar where you add an event by typing or saying one sentence, like "tomorrow 3pm dentist".

About
Adding an event to most calendars takes a dozen taps. zerocal takes one sentence. Type or say "next fri 7pm team dinner" and zerocal reads the date, time and repeat, highlights the words it understood and shows where the new event lands in that day, including anything it overlaps, before you add it.
Sentences are interpreted on the iPhone. There is no account, no server, no ads and no tracking. zerocal shows events from calendars already on the phone (iCloud, Google, Outlook) and can save straight to them. Voice entry tells English and Korean apart on its own.
Entering events by sentence and by voice is free with no limit. zerocal Pro adds repeat recognition inside sentences, lock screen and "Add by Voice" widgets, and more highlighter colors and designs.
