Give your customers a page where they pick a time and book themselves in. Astrocal checks your calendar so you're never double-booked, sends the confirmations and reminders, and drops every booking straight into your diary. Built for consultants, coaches, tutors, trades and anyone who runs on appointments.
A live booking page, not a video. Pick a time and book it.
No setup project, no manual. Most people are done before the kettle boils.
Your booking page is live straight away. We set you up with a 30-minute appointment, Monday to Friday, nine to five. Change any of it later.
We only offer times you're actually free, and every booking lands in your diary. Works with Google, Outlook and Apple calendars.
Put it in your email signature, your Instagram bio, or on your website. Customers book themselves in.
The admin that eats your evenings: confirmations, reminders, reschedules and payments, handled without you touching it.
We check your connected calendar before offering a time, so customers only ever see slots you're actually free for.
Every booking gets a confirmation email with a calendar invite attached, plus a reminder before the appointment. Nothing for you to remember.
Every confirmation includes cancel and reschedule links, so changes sort themselves out and your diary stays up to date.
Connect Stripe and charge for appointments at the moment of booking. Eligible cancellations are refunded automatically.
Drop the booking form straight into your site with a small snippet, or simply share your booking link anywhere you like.
Your booking page carries your name and your branding, not a big Astrocal badge.*
A simple dashboard shows every booking in one place: who's coming, when, and how to reach them.
Discovery calls, sessions and follow-ups booked around your week, with payment taken upfront if you charge for your time.
Astrocal for freelancers→Let students and parents book lessons and office hours themselves. Reminders cut the no-shows.
Astrocal for education→Quotes, callouts and site visits straight into your diary while you're on the tools, not on the phone.
Everything above sits on a REST API with an OpenAPI 3.1 spec, webhooks, and an MCP server that gives AI agents ready-made scheduling tools. Embed the whitelabel widget with one script tag, or build a fully custom booking flow.
