ICSx⁵ supports

  • iCalendar resources at HTTP/HTTPS URLs (often called Webcal)
  • iCalendar files on the external storage (using Storage Access Framework)

Setup

You can subscribe to iCalendars (.ics files) with two methods:

  1. Follow a link in your browser (for instance, “subscribe calendar” on webcal.fi) Select “ICSx⁵” if you’re asked which app shall open the link. Only webcal[s]:// URLs are supported via this method.
  2. Or tap “+” in the ICSx⁵ main activity. Then you can enter the URL or click “Pick file” and choose a file from storage.

In both cases, the ICSx⁵ “Add subscription” activity will appear. Enter user name and password, if required and click on “Next”.

Then, enter a title and select a color for the calendar. If supported by the resource, a calendar title will be suggested. You can change title and color later.

Always use HTTPS URLs to protect passwords and sensitive event data!

Daily use

To force a synchronization of all subscriptions, swipe the subscription list in the ICSx⁵ main activity. You may also “refresh” the calendars in your calendar app (if available).

In the ICSx⁵ main activity, you can also

  • set your synchronization interval, and
  • single-tap existing subscriptions to edit/delete them.

Using QR codes

To bring an .ics URL from the desktop to your Android device, you may generate a QR code and scan the barcode with your Android device.

Then open the URL with the browser and it should pass on to ICSx⁵ (doesn’t work for all configurations).
