This is the best, most reliable, affordable, and thoroughly configurable, calendar app around. I’ve missed it ever since I switched from android to iphone. Sorry to see it’s not available for my new device. Anyhow, get the app if you can. I’ve tried many others and searched and looked into most everyone availble to android and ip. A+ is the best. I miss it!

Just saw that I bought the original Acalendar+ a very long time ago, think it was a $1 because I just saw my review for the 2nd version dated in 2015. Best calendar ever, id be lost without you. My brain doesn't always remember stuff andvlose stuff often but you are always there to help. Auto updates with Google calendar, friends and family dont need this app to synch with their Google calendar is probably the best feature. I prefer monthly view and can still read it clearly. I recommend all!

It's been a lifesaver. I've been using it daily for 8 months. I bought the paid version after only a day or two. I have had ZERO issues and ZERO regrets. I have always had problems keeping a calendar and with missing appointments. Now I'm always on time. This app by itself justifies using a smartphone. It's easy to use and intuitive (a word I rarely use about software). UPDATE after 3 years. I wish every app was as reliable and well designed as aCalendar+. It is without question the finest, most well thought out app that I have ever used. I still have no regrets about my purchase. The upgrade to a Calendar 2 was well done with many pleasant design and usability enhancements.
