People in the three fields of occupation came to this idea probably independently. Stephen Covey studied the "habits of highly effective people" , Jim Loehr and Tony Schwartz studied the ways to achieve the highest results for top-flight athletes as well as the corporate managers  and Dr. Bill Hettler studied the wellness .
To keep the balance requires as wrote Stephen Covey , "running from one area to another fast enough to spend time in each other on regular basis".
This is not an easy task because we tend to do what seems to be urgent now and neglect what is important but not urgent. However, if we neglect an activity that is important but not urgent too long, it eventually provokes the crisis. Here the Activities and Priorities can help.
In Activities and Priorities (AAP) the priorities depends not only on time that you spend on the activities but on time as such. If you simply do nothing in a life dimension, its priority gradually increases with time, and after several weeks you see that the danger of the crises is high and the normally not urgent activity actually has become urgent.
So, AAP shows what activity is of the highest priority now and to what extent the activity is neglected or overdone.
Naturally it is up to you to determine what the set of activities you need to "train" because they are either too neglected or too addictive for you personally. It is also up to you how you call them. As the example we will use one of the simplest and typical set: work, family and cardio (aerobic exercise). You may add up to one hundred activities. However we believe that rare a person needs and ables to watch more than a dozen.
In the Wellness Time Management Guide there is a rather complete set of activities, which are important for most of people as well as the recommended time you should spend one them.
In the Guide to Dynamic Time Management a more heuristic and intuitive approach to the selection of the activities is outlined. Also, in this guide the advices about the time consolidation as well as the amount of time one should spend for the different type of the activities are given.
AAP does not requires from you to observe the strict schedule, however it does urge you to spend for the given activity the time that you planned to spend in a week.
In AAP you don't assign the priorities yourself. It seems senseless for the life dimensions because all they are equally important.
The most neglected activity has the highest priority and is in the top of the list. So you see at a glance what is more important to do now.
AAP does take time into account. If you spent no time for an activity its priority will gradually increase with the characteristic time of one week. AAP measure the absolute priority in the scale from 0 to 100. If you just start the activity and spend the time in a week according your plan, initial priority in couple of weeks diminishes from 100 to normal values. You will see it by the emoji, color and space shift.
The normal priority lies in the central lane of the "life road" and has the white or green color. The absolute value for the normal priory lies approximately between 67 and 33 with average 50. However, the absolute value is naturally just a qualitative estimation and is shown just to see the degree of difference between the time to spend for activities relative to the plan.
To estimate whether the activity is in a good state it is more important, in which lane of the "life road" the priority is and what color it has. The neglected or "not trained" state corresponds to left lane, the normal state to the middle lane and the overdone state to the right one.
To use AAP your first set how much time you plan to spend for the activity in a week. The time naturally depends on the kind of the activity as well as on the time and obligations you have. For instance, for the work it is usually 35 hours in a week, for the cardio about 3 hours (three days, one hour per day), for the family you might set 14 hours a week etc.
When you first set the planned time you will be given the opportunity to select what time (if any) you spent in the previous weeks compared to your plan. You also may enter how much time you spent in a particular day of the current week.
Then you just enter approximately how much time you spent for the activity in a given day. You may enter for today or up to seven day back. It is no need to remember the exact value. Several minutes difference doesn't matter.
Again, you always see at a glance what activities are of more importance now. We believe that it is especially useful for busy persons who have many things to do and have to select and prioritize.
We hope that AAP will help you to stay productive and happy.

AAP Plus Groups has the additional group view, in which you create the groups and select the existing activities to include into them. The same activity can be the member of several groups. All the not grouped activities are automatically included into the special "Not Grouped Activities" group. The priority of the group is defined as the priority of the activity that has the highest priority among the group members.
AAP Plus Groups is the additional AAP feature (starting from version 2.0) and requires the one-time in-app purchase.
