Only missing one thing I'd find useful. I use this to keep track of when my bills are due. I'm paid weekly. But I'd love to see the option for a check box to strike out the event after I've paid that specific bill so I know what I still need to pay and what has already been paid. "I can sort of do this in tasks but it doesn't have the alarm features color pick etc." Would be easier to add the finished check box option to the calendar side. Thanks!

Been using the app for a few months now and thought I could post a small review. Yes, it has a moderate amount of ads (for only ~1 euro they are forever gone), but the benefits easily outweigth this small inconvenient. My absolute favorite feature is the hybrid widget view which allows you to see smoothly the tasks and the events of the picked day from the selected month. Thank you for this software and keep up the good work! LE: the print calendar feature is the best one out there!

Overall, this app has been very useful so far. I just wish i could drag and drop events/tasks in the schedule page to change the scheduled time. Also, I wish that there was an option to control all day tasks showing first on the weekly and monthly pages. I personally would prefer to see my scheduled events but the all days tasks block out the events because there are first.
