The Calends app icon Calends

Many Apple calendars.
One to share.

Right inside Apple Calendar

Most of us have calendars scattered everywhere (work, personal, the kids' school and teams) and the ones you'd most want to share, like a locked-down work Outlook or Exchange calendar, are the ones you can't. Calends merges the calendars your devices already sync into Apple Calendar into one master calendar that lives right inside Apple Calendar, share it with anyone or keep it private. It never logs into your accounts, so even locked-down work calendars can finally join, with nothing for IT to block.

What Calends does

All your calendars in.
As many shareable ones out as you need.

Calends pulls together everything already in your Apple Calendar (every account, every subscribed feed) and merges it into clean, shareable calendars. Build as many as you need, each showing exactly what its audience should see. Your original calendars stay exactly as they are. You keep adding events to them just like before, and every merged calendar updates itself.

👪

One calendar for the family

Every school, sports and activity feed you subscribe to (plus both parents' schedules) merged into a single family calendar that's on everyone's devices.

💞

Your whole schedule, for your partner

Hand your partner your complicated work life (on-call, clinic, shifts, travel) as one calendar they simply subscribe to and always see.

💼

Just enough, for colleagues

Mix and match so colleagues and assistants see only what they need, or share busy-only, so they see when you're free to meet, never the details. You choose the wording too: each calendar can carry its own label, like Reserved, or show its name, as in Clinic: Busy.

No other app does this without logging into your accounts (OAuth) or charging a monthly subscription. Calends needs neither. It reads what's already on your device, and because it works right inside Apple Calendar, every calendar you build stays synced on all your devices automatically.
How it works

Three steps. Then it's automatic.

1

Create a master

Name it, give it a color. Calends creates it as a real calendar right inside Apple Calendar (in your own iCloud). It shows up alongside your other calendars, on every device.

2

Pick what feeds it

Check any calendars Apple Calendar can see: iCloud, work accounts like Outlook or Google, subscribed feeds, calendars shared with you.

3

Share and forget

Share the master from Apple Calendar like any calendar. Calends keeps it filled, deduplicated, and current in the background.

Calends isn't another calendar app to live in. The master it builds is an ordinary calendar inside your Apple Calendar. You keep using Calendar exactly as you do now. And your source calendars are never modified: Calends only ever writes to the master it maintains, so delete one anytime and every source stays exactly as it was.

Privacy, in detail

Share the shape of your day.
Keep the parts that are nobody's business.

Sharing a calendar is normally all or nothing: every detail, or no calendar at all. Calends decides per calendar, and even per event, so one shared calendar can carry your whole week without carrying your whole life.

08:00 – 09:00Lab meeting
09:30 – 12:00Clinic: Busy
13:00 – 14:00Reserved
17:30 – 18:20Emma football

One day as the other person sees it: a meeting in full, a clinic that shows only as busy, an appointment under a label you chose, and your daughter's practice you deliberately left readable.

🎚️

Per calendar, in your words

Every calendar feeding a shared one shows full details or just a busy block, decided one calendar at a time, so work stays opaque while the family feeds stay readable in the same calendar. "Busy" is only the default: call it Reserved, In clinic, or anything you like, and add the calendar's name where it helps, as in Clinic: Busy.

✏️

Rewrite what's copied

Title rules rewrite event titles on the way in: shorten them, strip a prefix your workplace adds, or replace a title with wording of your own. The events in your own calendars are never changed, and you can undo a rule as easily as you added it.

🎯

Down to single events

A whole calendar is rarely sensitive. Name a word and those events keep their details inside an otherwise busy-only calendar, let all-day markers like London through while timed events stay busy, or drop noise like Lunch altogether.

This is not a privacy setting on somebody's server. Calends decides what to write before it writes anything, so a detail you held back is never copied at all, not into the shared calendar, not into iCloud, and not to us. There is no server of ours for it to reach.
How it compares

All the merging. None of the middleman.

Most calendar-sync tools route your accounts through their own servers and charge every month. Calends stays entirely inside Apple's ecosystem, and you buy it once.

Questions

Your questions, straight answers.

Do the people I share with need Calends?

No. A master is a completely normal calendar. You share it from Apple Calendar, and recipients simply subscribe like they would to any shared calendar. Calends is only needed on the side that builds it.

Can I use it at work, does IT need to approve anything?

Nothing new touches your work account. Calends doesn't log in, doesn't ask for OAuth grants, and has no server. It reads the work calendar your Mac or iPhone already syncs through Apple Calendar, and writes an ordinary iCloud calendar. There's no app for IT to approve, which is why Calends works in places that block calendar apps that sign in. And with busy-only mode, colleagues see when you're committed, never what.

One exception worth knowing: if your employer installed your work account on your iPhone through their device management system, that account is hidden from every third-party app on the phone, Calends included. Macs have no such restriction, so building the merged calendar there gets it onto your phone anyway. How work calendar blocking actually works

Does Calends change my original calendars?

Never. Calends copies events into the master it maintains and only ever writes there. Your sources (including work accounts and subscriptions) are read, never touched. Delete a master anytime; sources are unaffected.

Do I need to use Apple Calendar?

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 in Settings and removes it from nowhere else. Many people add Apple Calendar just to use Calends.

What if two of my calendars have the same name?

On the device where you tick a calendar, Calends records exactly that one, so two calendars with the identical name, most often a work Calendar, or a Holidays or Birthdays feed that shows up in more than one account, are no longer confused. Because a calendar's identifier is specific to each device, 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 (say Work, Outlook), best done on a Mac, since iPhone and iPad usually won't let you rename a work (Exchange) calendar.

Will I know if something stops syncing?

Yes. Calends watches its own plumbing. If a calendar ever needs attention, a work account signed out, a source gone quiet, every one of your devices gets a notification naming the calendar and the device it happened on. It travels through your own iCloud, no server of ours involved, and event details never leave your account.

Is it a subscription?

No. Calends is free for 30 days, then a single $19.99 purchase unlocks it for good, across Mac, iPhone, and iPad, with Family Sharing included.
