At this time we are not actively developing a version of Informant for Windows.
For our Windows users with Outlook we offer Informant Sync For Outlook, a "sync connector" that you can use connect Informant to Outlook and sync the calendar and task data between the two applications for more details see the following link https://www.pocketinformant.com/informant-sync-outlook/
We do offer our Informant for Web platform which is available to Windows PC's. Informant for Web can be reached here:
Informant for web will only show information that is being synced with an Informant Sync calendar. You can see what calendar your events/tasks are being saved to by tapping on an event/task and tapping on the field that shows the calendar chosen for this item. Here you will see a list of calendars under the header of the sync service they are assigned to. Be sure you are saving them to a calendar listed under the Informant Sync header.
