Ratings and reviews

I love this app, it has really helped me be more organizedand not schedule myself for 2 things at once by accident. I use Teams for work and Google calendar for my personal life, and I love that I can see both so when I'm scheduling something I can see if it conflicts with anything else in my life. Also when things automatically upload to any calendar they go here as well.

4 stars because when you change the font size or zoom your display on Samsung the text doesn't wrap. I wish there way a way to change text wrap settings and to change fot settings 😕 other than that it's an awesome app! --- Also, when are you going to add multiple time reminders? Quite a few people requested this feature 5years ago and you haven't done anything about 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.
