CalenGoo can also view and edit the iOS calendars. So you can see your iOS calendars (e.g. your Exchange calendar) and your Google calendars together in the same view. Just turn "Settings", "Display and Use", "General", "Show iPhone/iPad/iPod touch calendars" on. Please see here for details: iOS calendars

You can sync CalenGoo directly with multiple Google Calendar accounts in addition to your iOS calendars. Just add them under "Settings", "Accounts" in CalenGoo. When syncing directly you can also assign icons to events.

Google's event colors allow you to assign different colors to your events. Please see here for details: Event colors

For an overview which rules CalenGoo supports, please see here: Recurring events

If you are syncing with Google Calendar, you can use SMS, email and pop-up reminders. If you are not syncing with Google Calendar you can only use pop-up reminders. However pop-up reminders have a few advantages, e.g. they also work without mobile-phone reception and you can configure them to repeat the alarm every minute or to snooze the alarm. Please see here: Reminders

You can create a template from an event to use it later to create new events from it. Templates can also be limited to certain attributes of the event, e.g. so that they only contain a location or a list of attendees. By adding multiple templates to a new event this way, you can use e.g. the location and the attendees from different templates. Here you can find further information: Templates

There are over 100 icons provided (if you download the additional icons) and you can also add your own icons. Please see here for details: Icons

Floating events are events that have a checkbox to mark them as completed. Completed events are displayed crossed out. But the important thing about floating events is that they cannot move out of sight until they are completed. CalenGoo checks if an uncompleted floating event is in the past (because a new day has started) and moves that event to the current day so that you won't forget it. Here you can read more about it: Floating events

You can have multiple calendars in Google Calendar and CalenGoo for different kinds of events (e.g. "Work", "Home", "Sport"). For each of these calendars you can give others (by entering their email address on the Google Calendar website) read access or even write access. This way these other persons can see your calendar in addition to their own. Because you can configure this for every calendar separately, you can certainly also keep calendars private. Please see here for further details: Shared calendars

When adding events you can choose email addresses from your contacts. The attendees will get an email with links to accept or decline the invitation. You can see their response in the event's details in CalenGoo. Please see here for details: Edit

The supported navigation apps are Navigon, Skobbler, Tom Tom, Sygic, iGo and Waze. CalenGoo checks which of them are installed and offers to use them to navigate to the specified location.

The search view can be configured to search in titles, descriptions, locations, attendees lists and tasks. It sorts the found events by their date and time.

The PDF files are created using the full printing resolution. There are several options to customize the way they look like. You can find further information here: Printing

Please see here: Tasks

These tasks are saved in the description field of the event. Please see here: Tasks in events

Please see here: iOS Reminders

With CalenGoo you can create photos or you can create a PDF file from multiple photos (e.g. to scan a document). These files can then be attached to an event and you can access them from your computer by using Google Drive (but not via the Google Calendar website, only via the Google Drive website). Please see here for further details: Attachments

When using the keypad you can tap "skip" to skip entering the date and jump to the time field. The keypad disables keys that cannot be used in that moment, e.g. the first digit of the minutes field can only be 0-5, so 6-9 are disabled.

CalenGoo will parse the parts of the event and tries to find the time, location and calendar in the text. Then you can create an event with these attributes with a single tap. Please see here for further details: Natural Language Input
