I've been using the the basic aCalendar app for several years and have really enjoyed it. Recently I decided to try aCalendar+ and paid the fee. Really bad idea. After getting The "+" version installed I found that absolutely none of my scheduled events from the basic version transferred to the "+" version, meaning you're starting from scratch, both historical and future entries. There is nothing in their help section to help in anyway. I tried contacting them for assistance and got nothing.

I cannot find any support request from you. Please send again to ACalendar and aCalendar+ both access the android calendar storage, so there is not even a transfer or synchronization required (the plus version does import the aCalendar settings though on first start) and you are the first to ever report such a problem.

I have been using this app for years and years and absolutely love it. I got the paid version mainly to support the developer. I especially love the weekly view...originally because it simulated the style of physical day planner I used to buy. I also use multiple calendars (mostly google) and like to see the entries color coded in a single view. Sometimes I intentionally set up separate calendars just to see things color coded (ex. Gym class schedule on a separate calendar).

I've been using this app for years, and upgraded to the paid version. Overall I like the calendar UI, but am less happy with tasks. Most importantly, tasks stopped syncing somewhere in the last month or so. Also, the UI for setting a reminder is not intuitive. I may have to find another tasks app.
