Readdle, the leading publisher of business and productivity applications for iPhone and iPad, updates Calendars, its popular iOS application for tracking events and appointments on the go, with "transparent" Google Calendar sync and other additions. With Calendars 2.3 people can instantly add, edit or re-schedule events and tasks within the application.

Calendars combines all the best features of online Google Calendar with seamless performance and style of the native iOS application. All changes in tasks and events are immediately synced with the web in the background avoiding any interruptions during the work. The sync process is "transparent" from the user's standpoint meaning they should never notice it.

"Everything is fast in Calendars 2.3. It's very fast to look up for events, create new appointment or check your schedule. Combined with intuitive interface this makes Calendars 2.3 great choice for both new and long time Google Calendar users," says Alex Tyagulsky, Readdle CMO.
