Ready for Veri*Factu

Nutritionists already trust Átomo.

Less admin left hanging, and more time to care for your patients.

“WhatsApp used to be the practice: confirming times, chasing payment, counting pack sessions by hand. Now patients book and pay on the page, and I know where things stand without chasing anyone.”

Your practice should not live in your head.

Appointments, payments, packs and invoices are necessary. They should not interrupt your consultations.

  • Closing appointments over messages
  • Checking who has paid
  • Counting sessions in each pack
  • Preparing invoices one by one

With Átomo

  • The patient picks and confirms a slot
  • The payment stays attached to the appointment
  • Sessions stay under control
  • Every payment stays linked to its invoice
