How to book on AionClock, step by step
Search for the service near you
Open the app or www.aionclock.app, turn on your location and type what you need: a haircut, physio, lessons, a repair. You only see professionals in your area.
Compare before you decide
Every profile shows price, duration, distance, whether they travel to you and ratings from other clients.
Pick a genuinely free time slot
The calendar comes from the professional's real schedule, with the time between clients already taken out. If a slot shows up, it can be booked.
Confirm and forget about it
The professional gets the booking instantly. You get the confirmation and reminders 24 h and 1 h before by push, email or WhatsApp.
A fact you can check
On AionClock nobody can take the same slot twice: the database rejects it (an exclusion constraint in PostgreSQL), not a warning on screen. A 409 “slot taken” is the normal answer when two people ask for the same time.
Frequently asked questions
Does booking on AionClock cost anything?
No. Booking is free and AionClock charges no fee. The professional sets the price of the service and you pay them directly, as always.
Do I have to call or message to confirm the time?
No. The time slots you see are already free, so booking closes the appointment. If the professional prefers to approve each booking, you get a notification when they accept.
What if someone else picks the same time as me?
Only one of the two bookings goes through: the database rejects the second. Whoever arrives later sees the slot as taken and picks another. No double bookings.
Can I make an appointment without installing the app?
Yes. On www.aionclock.app you search, sign in and book the same way. The app adds notifications on your phone and search by GPS.
Is scheduling an appointment the same as booking one?
Yes. Whether you call it booking, scheduling or making an appointment, on AionClock it is the same gesture: pick a free time slot and confirm.
Next step
Download the app or search from your browser: you see the same openings in both.
