Ratings and reviews

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.

I have used this for over 5 years. I evaluated 5-8 other calendars by downloading them. This app offered most of the features I found are most often needed. Repeat function doesn't always get the right day of the week. Love the color coding!! 😍 11/23 update: after I changed to a new phone this summer the color coding no longer works without paying, hate that! Want to decrease to 4 stars, but can't!!; 2/24 just discovered i can use color coding again, LOVE IT!! 🥰
