If you aren't able to see your calendar items in Gneo's Forecast view, it may be that you have not allowed Gneo to access your calendar.
To give Gneo access to your calendar, go to your iPhone/iPad Settings > Privacy > Calendar and ensure Gneo is switched to 'On'.
If Gneo is not switched to 'On', switch it to 'On', fully close and re-open Gneo.
Gneo syncs with the calendars which you have on your device so please make sure that the calendars you wish to see in Gneo are first showing on your iPhone/iPad Calendar.
Please also ensure that you have selected the calendars which you wish to see in Gneo in Gneo's Settings. To access Settings, tap the middle button and Settings is on the top right.
You should now see your calendar items in the Forecast view. All of your calendar appointments and any tasks with a reminder date will be shown here so that you can manage your tasks around your calendar appointments.
