Every patient booked. Reminded the day before.
Patients call before the doors open and long after they close. Renggo books and moves appointments, reminds patients the day before and sends urgent calls to your staff.

Can I see a doctor on Thursday morning?
The day before, every slot confirmed.
In the evening Renggo reminds tomorrow’s patients. Confirmations come back, and a patient who can’t make it moves to a free time.

Renggo doesn’t make care decisions. You decide which calls go straight to your staff.
See where no-shows come from.
Every appointment, reminder and answer is counted, with a suggestion for what to change.
No-shows fell from 14% to 6% after reminders started.
Renggo suggests: Send reminders earlier for morning appointments.
