Appointment scheduling software for small business
ProtoSync is an online booking system for solo professionals and small teams. You publish a schedule of open time slots, clients pick a time themselves, and everyone gets a reminder before the appointment. No website to build and nothing to install — booking works from a plain link.
Why not just book over chat
While bookings live in a messenger thread, the schedule exists only in your head. Every "do you have anything on Thursday?" is a separate conversation, and one reschedule means recounting the whole day by hand.
A schedule instead of a thread
Clients see only the slots that are genuinely free and take them directly. Double booking is impossible: a taken slot disappears for everyone at once, with no page refresh.
Fewer no-shows
Reminders reach both the client and you — through Telegram, a browser push notification, or the phone. Forgotten appointments drop sharply, and a freed-up slot is visible immediately.
No website, no install
A schedule link opens in the browser, inside Telegram, and in the Android app. Clients do not download or register anything just to book a time.
How it works
- Create a schedule — give it a name, a city, and a service category.
- Define your slots: duration, working days, and breaks. You can release the schedule gradually instead of a month at a time.
- Share the link with clients — in a messenger, a story, or your profile bio.
- Track bookings and reminders: confirming, rescheduling, and cancelling each take a single tap.
What you get
- Online client booking from a link — no website of your own, no app to install.
- Slots of any length, plus breaks, days off, and gradual schedule release.
- Automatic appointment reminders for both the client and you.
- Manual approval, if you would rather confirm every booking yourself.
- A waiting list, so a cancelled slot goes to the next person in line.
- Custom fields on the booking form — phone number, service, or a note.
- A chat with each client inside the schedule, plus a group chat for everyone.
- Reviews and ratings shown right on the schedule page.
- Shared administration, so several people can run one schedule.
- Works in Telegram, in the browser, and as an Android app.

Frequently asked questions
- Do clients need an account to book?
- No. A client opens the schedule link and takes a free slot. Only you need an account — to run the schedule.
- How much does it cost?
- Running a schedule and taking bookings is free. Advanced capabilities are available through a subscription.
- Can I take bookings without a website?
- Yes, that is the main use case. Send the schedule link in a messenger or put it in your social profile bio — no separate website needed.
- Are appointment reminders sent automatically?
- Yes. Both the client and the provider get a reminder: in Telegram, as a browser push, or on the phone.
- What happens when a client cancels?
- The slot is released immediately and becomes available again. You get a cancellation notice and see the open window in the schedule.
- Can several people manage one schedule?
- Yes. You can add co-administrators — a second provider or a salon manager, for example.
