Would you recommend a booking service?

Question

Time Management

Recommend a service for arranging pre-registration of clients for negotiations.

Needs:
It is necessary that the client simply be able to reserve a specific time slot of 20/60 minutes at 9:30-11:00, 18:00-19:00 online. Simple design, similar to linktree business cards, preferably with an appointment reminder.

I looked at ~6 services, but did not find anything suitable:
a) some do not work correctly: registration does not complete; recording is available from 9:00, although the schedule is from 9:30; error about failed captcha, which is not displayed;
b) too many unnecessary elements that cannot be unscrewed: "About the company", "Offices", "Phone numbers", "Our address on the map";
c) interfering functionality: mandatory entry of the number, and you can enter only the number of the RF; You can't split the graph into 2 parts.

Answer 1

Recommended several services.
Calendly is exactly what you need. There is no unnecessary information, it is conveniently configured, at least somewhere there is an opportunity to copy the schedule by day. The only negative: UI for writing in English (there are others, but Russian is not available).
Torrow - on their self-employed demo page , everything looks great, but in 30 minutes of interacting with the site and the manual, I could not achieve a similar look. The service has many features, but they are redundant for me.

Answer 2

Have you looked at Google calendar?
