A booking system that upsells for you

assistapp.me turns any venue with bookable time slots, like golf bays, barber chairs, padel courts, or treatment rooms, into a branded booking widget and a WhatsApp assistant that books, confirms, and upsells add-ons automatically.

Online booking widget

A booking page customers already know how to use

No app to download, no account to create. Customers pick a date, a bay, and a duration, and they're booked in. The preview on this page isn't a screenshot, it's the real, working widget.

Real live availability, computed from real bookings, not a static mockup
Flexible durations (30 to 120 minutes) with per-tier pricing
No double-booking, even if two customers book the same moment
Offers a relevant add-on (like a lesson) automatically at checkout

AI WhatsApp booking assistant

Or they just send a WhatsApp message

Customers can check availability, book, and cancel entirely over WhatsApp, with no app or website visit needed. It understands loosely-phrased replies, not just numbered ones, and can answer real questions about your hours, prices, and services along the way — grounded in your actual business details, so it never invents an answer it doesn't know.

Ask "have you got a bay free tomorrow?" and get real available times back
Reply naturally — "the 6pm one please" books just as well as "2"
Answers questions like opening hours or pricing using your real business details
Cancel just as easily, right from the same chat
Offers the same automatic upsell as the booking widget, like a lesson or food and drink

Try it on WhatsApp

Opens WhatsApp with a message already filled in — send it to join the test line, then chat with the assistant like a real customer would.
