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.

  • Availability across every calendar

    Checks all your connected calendars at once. Never double-booked between work and personal.

  • Choose where bookings land

    Pick exactly which calendar new bookings are added to.

  • Set your own rules

    Meeting length, buffer time, available hours and days, and minimum notice before someone can book.

  • Bookers see their own time zone

    They pick a slot in local time; it lands correctly on your calendar.

Find a Time

Stop hunting for open slots. Let OCTRuTA find them.

  • Find a time, instantly

    Tell OCTRuTA how long you need and when to look — it scans every calendar for open slots.

  • Sensible suggestions only

    Respects preferred hours and leaves breathing room. No 6 a.m. slots, no back-to-back jams.

  • One tap to schedule

    Pick a suggested slot and OCTRuTA creates the event for you.

Protected Time

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.

  • Recurring protection

    Protect time that repeats, like a standing weekly workout or every evening with family.

  • Control which links it affects

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

  • See it at a glance

    Protected time is visually distinct on your calendar, so you always know what's yours.

  • Undo anytime

    Remove protection whenever plans change and free that time back up.

People with too many calendars, finally calm.

I stopped accidentally booking work meetings during my kid's pickup. That alone was worth it.

Private by design

Your calendar is the diary of your life. We treat it that way.

Credentials are encrypted

Your calendar account tokens are encrypted at rest. We never see your password.

No ads. No tracking. No SDKs.

We don't sell data because we don't collect it. OCTRuTA is funded by Premium subscriptions — that's it.

Most data stays on device

Your events are cached locally so the app is fast offline — and there's nothing to leak in a server breach.

FAQ

Questions, answered.

Which calendars does OCTRuTA support?+

Google Calendar, Apple iCloud, and Microsoft Outlook (personal and work/tenant accounts). You can also subscribe to any private iCal feed URL to pull in calendars that don't live in a major account.

How is OCTRuTA different from Calendly?+

OCTRuTA is a full mobile calendar app first — Calendly-style booking links are built in, but you also get a unified multi-account calendar view, Find Time, and Protected Time in one place.

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.

What's included in Premium?+

Shareable booking links with rules and per-calendar routing, the Find-a-Time tool, and Protected Time blocks (including recurring protection and per-link controls). Everything else — connecting calendars, editing events, widgets, attachments, offline access — is free.

How much does Premium cost?+

About $4.99 per month or $39.99 per year (a 33% saving). Pricing is handled by the App Store and Google Play through RevenueCat.

Is my calendar data private?+

Yes. No ads, no tracking, no analytics SDKs. Your calendar credentials are encrypted and most of your data stays on your device. OCTRuTA only accesses what's needed to display events and compute availability.

Does it work offline?+

Yes. Your events are cached on your device, so you can check your schedule even without a connection. Changes sync back to the source calendar as soon as you're online.
