The only calendar that allows everything we need in scheduling appointments for our salesmen. Has GPS, easy movement of appointments for cancelations or last minute add- ins, and allows notes on client request . Everything is on one page, so there is no going back and forth to view time, date, address, or notes. The reminder alarms are an added bonus for us. There is no need to train on this calendar because it is pure simplicity at it's best.

this is the most user-friendly, organized, simplified, and very manageable Callander I have ever found. The one and only drawback is that I can't schedule several reminders 15 minutes apart. I am legally blind, my reminder is vibration more than visible. My watch is also tuned to vibration alarms. 15 different alarms in a day is not distracting to any other person.

It does everything that I wanted to do and is connected to all of my other calendars. The sync is much faster than other apps that I have used. Edit 3/10/24: Yup still use it. I am not as business savvy as a lot of other people but it does everything I needed to including tracking appointments and making my own stuff on a daily or weekly basis repeating items daily weekly and whatnot. Still like it, will keep using it.
