Does exactly what it was designed to. The only minor issue is that it raises a notification immediately after failing to sync due lack of internet. Ideally it should wait for the connection and then sync silently. Only warn the use if the connection failed with Internet on.
Great!
Works great for porting a calendar that you require a subscription for onto your Google calendar!
A hidden gem of an app, so helpful for adding external calendars (in my case Proton) into the Google system so to appear in widgets, on watches, etc. Couldn't live without it.
Exactly the app I was looking for. It just works!
Finally, a calendar sync that works! Outlook and Google calendar share synchronization is garbage compared to this app. You can set down to a 15 min sync interval, unlike the others which seem to take 24 hours and doesn't grab all the events. This app is well worth the nominal cost.
Incredible app, works like a charm.
