Regularly for Android: Keep track of tasks without fixed calendar schedule

There are tasks in life that follow no regular schedule. Think about cleaning the computer keyboard, mopping the floor, going to the dentist for your check-up or changing your car's oil. With these type of activities or tasks, it does not really matter if you do it a day or two early or late as it does not really matter most of the time if you do your yearly health check-up 370 days after the last one and not exactly 365 days.
Regularly for Android is a handy smartphone app that helps you keep track of these tasks in a well designed fashion. The main idea behind the application is to keep track of these tasks and their schedules for you so that you won't forget them ever again.
You can use a list of built-in suggestions on start to add to your task list, or start with a blank list instead. Tasks can be tagged so that they fall into one or multiple categories which you can look at individually on the apps' start screen. The application displays all tasks by default on its front page, but you can swipe to the right to look at individual tags instead.
Each task is listed with its name, usually the activity it involves, and the due date on the right. You create new tasks with a click on the plus icon at the top. Here you select a name, period or frequency in which you want the task to be repeated, the date it has been last done, and details about the task if you want. You can furthermore add tags to the task and add previous activities to the log.
All tasks on the home screen are sorted by an urgency score that is shown by color. Green usually means you have enough time and everything is in order, will tasks colored in red colors need your attention. You can log tasks as done by long-pressing them in the task list so that you do not have to do so individually.
The app supports notifications but uses a dynamic system instead of a fixed one to remind you of tasks that you may need to do. It also groups notifications together so that you will never be bombarded with notifications.
Verdict
Regularly closes the gap between Android's calendar app and to-do applications. It is useful for all activities and tasks that you have to or want to do regularly and be reminded about, but that are not recurring on a fixed schedule. The app is easy to use and settings tasks as done for the period provides you with a great overview of all of your recurring activities.
Or you could use ToodleDo (http://www.toodledo.com), which does calendar driven and tasks like this in one package — and has “contexts” so that reminder to check the oil level in the cabin fuel tank comes at the a useful time. It has clients for Android, iOS, Win8, and more. It also has an effective website, email reminders, email task creation, “download your data” functionality.
I’ve been using it for years — check it out.
