Nokia Wellness Diary is probably one of the most useful apps you can find for your Symbian phone. It gives you the opportunity to keep track of your daily dietary and fitness activities without relying to an external paper diary.
Wellness Diary offers many variables to choose and keep track of. The range is great: weight, eating, sleep, exercise, alcohol, doctor visits, etc. Many aspects of a normal or less normal life can be taken into account. For example, I found very interesting the fact it has a blood sugar variable for diabetic users. Maybe it's not the most scientific way to keep track of your glucose levels, but it's certainly a nice help for the less fortunate ones.
Various exercise types are available to choose from the program's database and the user can make new ones as s/he sees fit. Personal goals can also be arranged.
The nice thing about this app is that it can show all the above information in easily read graphs that follow time trends. This way the user can follow his/her progress and adjust accordingly. I personally used this app with Sports Tracker to keep track of my weekly progresses in my fitness program, while trying to change my dietary habits. It all worked well up until the incompatibility issue with the other app.
The Wellness Diary is a nice application to have if you are into a wellness program, personal or imposed by a trainer. It will definitely make it easier for you to achieve your goals. Nevertheless, there are many things that can still be improved. For example, I find the "micromanagement" needed too much of hassle. There are many entries so, unless don't you want to be accurate, you have to be always with the app open and entering data. I would love to see a "lite" version from the settings where for example you don't need to place each meal's energy by kcal, but an approach with food slots from each category (carbohydrates, proteins, etc).
Another thing to be fixed is the incompatibility with Sports Tracker. These two programs should be united in my opinion. Diet and fitness go almost always together, nowdays, so I hope for a major overhaul and union of both applications.
