Scheduling, Appointment, Mentoring Apps Suggestions

Hello all,

I’m looking for some good apps that I can suggest to my fellow priests in our Diocese.

My system is utilizing Omnifocus and Fantastical.

But I’m also looking for free options to suggest, if needed.

Looking for good apps that can help with
Time Managment
Appointment Scheduling
Mentoring App that has notes, date last met, etc.

Thank you.

Trello is probably a good start.
It’s “index card” paradigm can be very intuitive.
It’s also possible to create groups, notifications, etc.
Free or paid.
