Ratings and reviews

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.

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.

I use apple, Google and Microsoft devices. I was looking for a good integrated app with ability to customize features and appearance while keeping integrity of the content and ease of viewing. The installation went well and loaded across devices. Worked on customizing on my mobile Apple device first due to challenging number of activities and appointments going out over 1 year. Took time to get through the options, but formatting and accuracy turned out perfect. Highly recommend!!
