Calends
Calends isn't a standalone calendar app — it builds one master calendar right inside the Apple Calendar you already use, folding many of your calendars into a single one to keep for yourself on every device or share with anyone. Here's how it works.
Open Calends and tap the + button to create a master calendar — a real calendar that lives inside Apple Calendar. Name it and give it a color.
Tap the new master and check which of your existing calendars should flow into it — iCloud, work accounts, school feeds, anything Apple Calendar can see.
Within a minute, the master is populated with events from those sources — deduplicated, filtered, and kept current in the background.
It's already on all your devices through iCloud. To share, send it from Apple's Calendar app the same way you'd share any calendar.
Not one you have to live in. Calends builds and updates your master calendar, but the master itself is an ordinary calendar right inside Apple Calendar — so you keep using Apple's Calendar app (or Outlook, or Google) exactly as you do now. You only open Calends to create a master or change what feeds it; the rest happens quietly in the background.
In your normal iCloud calendars. Calends doesn't move them. It writes copies into the master calendar you create — which is itself a regular calendar right inside Apple Calendar. Your original events are never touched.
You can, but we recommend editing the source. Edits to source events flow through to the master automatically. Edits to master events stay there but don't propagate back.
The master is removed from your devices. Your source calendars and all the events in them are untouched.
Calends syncs your master calendar settings through your private iCloud account. The events themselves live in regular iCloud calendars, which Apple syncs as usual. Only one device runs the active sync engine at a time — if you see a banner saying "Sync is running on [another device]," tap "Take over here" to switch.
On the device where you tick a calendar, Calends uses exactly that one — so two calendars with the identical name (a work Calendar, or a Holidays or Birthdays feed that appears in more than one account) are no longer mixed up. One nuance: a calendar's identifier is specific to each device, so that exact match applies only where you made the pick — on your other devices, tick the right one there too. To fix it everywhere at once, give one a distinct name in Apple Calendar; best done on a Mac, since iPhone and iPad usually won't let you rename a work (Exchange) calendar.
The one-time purchase includes Family Sharing. Anyone in your Family Sharing group can install Calends from their own Apple ID and get the same access — no extra purchase.
Calends works through Apple's built-in Calendar app — but you don't have to switch to it. Your work or Google account can live in Apple Calendar and in Outlook or Google at the same time; adding it to Apple Calendar is a quick, free step (iPhone/iPad: Settings → Calendar → Accounts; Mac: System Settings → Internet Accounts) and removes it from nowhere else. Many people add Apple Calendar just to use Calends.
