Comments on ICSx⁵ – Subscribe to calendars for Android

★★★★★ Nathan · Feb 12, 2024

Works great for porting a calendar that you require a subscription for onto your Google calendar!

★★★★★ JC Denton · Aug 24, 2018

Hidden gem! Google Calendar has a huge flaw in that it only syncs external calendar feeds (ical) every few hours (sometimes you have to wait 24 hours). Therefore, it is useless for any external calendars that you frequently update. I spent a lot of time looking for alternative calendars but most pull data from Google Calendar instead of directly importing ical feeds themselves. This app solves that problem. It is not a calendar, its only purpose is to import ical feeds. Then this app automatically makes each imported calendar available in Google Calendar. I'm not sure how this works as there is no setup, all my imported calendars automatically became available in Google Calendar. Regardless this app is a workaround for a persistent issue on Android phones that rely on Google. Very happy.

Barney Fife This is a great app that works very well for me. If it tries to run a scheduled sync when I don't have internet signal, it gives an error notification (a feature, not a bug), but when I'm back in signal I sync it manually, and it works perfectly again.

★★★★★ Jeremy Barnes · Jul 9, 2019

This does exactly what it said it would. It syncs my work calendar by periodically downloading an ICS

★☆☆☆☆ Carlos Munoz · Nov 10, 2021

It works at first but after a while the sync stops and can't resolve the name. And the iCal events have changed, but it doesn't reflect on calendar in my Phone. 😭, Update - 11/2/21. Now my autosync is disabled with no reason. So I have to make manually update it. - Update 11/10/21 - I followed the instructions to make sure the app doesn't go to sleep but events that are on my calendar will have been updated with new date and time won't reflect through the app. Lost a star for it.

★☆☆☆☆ A Google User · Oct 7, 2015

So much promise Crashes upon syncing local file and fails to parse the same file when done over the web. I expect better from a paid app.
