Booking Links
Let anyone book you — without the email ping-pong.
- ✓
Shareable booking links
Send a link and let people pick a time that actually works.

Stop hunting for open slots. Let OCTRuTA find them.
- ✓
Find a time, instantly
Tell OCTRuTA how long you need and when, and it scans your calendars for open slots.

One tap to schedule
Pick a suggested slot and OCTRuTA creates the event for you.

Protect the time that isn't on a meeting invite.

Protect your personal time
A workout, family dinner, focus block — booking links treat it as busy.

Control which links it affects
Hide it from your work link while keeping it bookable on a personal one — or block them all.

FAQ
Questions, answered.
Which calendars does OCTRuTA support?+
Google Calendar, Microsoft Outlook (personal and work), iCloud via CalDAV, any private iCal or webcal feed, and the calendars already on your iPhone.
Which calendars do booking links check?+
Google, Outlook, iCloud connected through CalDAV, and iCal feeds, checked live when someone books. You choose which calendars each link checks. Calendars that exist only on your iPhone can't be checked, so connect iCloud with CalDAV to include it.
Can't connect your work account?+
Some employers' IT settings require admin approval before apps like OCTRuTA can connect to a work Microsoft 365 or Google Workspace calendar. If you see a "Need admin approval" or "blocked by your organization" message, you can ask your IT team to approve OCTRuTA, or try one of these:
- Add it to your iPhone's Calendar app. Go to iPhone Settings → Calendar → Accounts and add your work account, then add it in OCTRuTA as a device calendar. You'll see and manage your work events in OCTRuTA, but booking links can't check device calendars.
- Use a published calendar link, if your organization allows it. In Outlook on the web: Settings → Calendar → Shared calendars → Publish a calendar, then copy the ICS link. In Google Calendar: Settings → select the calendar → "Secret address in iCal format." Add the link in OCTRuTA under Add Calendar → calendar link. Booking links can check it, but it's view-only in OCTRuTA.
How is OCTRuTA different from Calendly?+
OCTRuTA is a full calendar app first. Booking links are built in, and they check your personal and iCloud calendars too, not just your work account.
Do guests need an account to book me?+
No. Anyone with your booking link visits a timezone-aware web page, picks a slot, and gets a 10-minute hold while they confirm — no signup required. They can reschedule or cancel from their confirmation.
What's included in Pro?+
Booking links (with calendar choice, rules, questions and automatic video links), Find Time, Protected Time, and sharing your calendars with others. Everything else, including connecting calendars, editing events, search, widgets, attachments and viewing shared calendars, is free.
How much does Pro cost?+
$4.99 a month or $39.99 a year (save 33%), billed through the App Store. New subscribers get the first month free.
Is there a free trial?+
Yes. Pro is free for your first month, and you can cancel anytime in your iPhone settings before it ends.
Is my calendar data private?+
Yes. No ads, and we never sell your data. The app includes a lightweight attribution SDK that tells us which marketing brought you to OCTRuTA, and that's the only tracking we do. Calendar credentials are encrypted. For booking links we store only busy times, never event titles or details. See our privacy policy for specifics.
Does it work offline?+
You can view your schedule offline, since events are cached on your iPhone. Creating or editing events needs a connection.
Is there an Android app?+
Not yet. OCTRuTA is iPhone-only for now, and Android is on the way.
