Great app, super stable, flexible export as csv file or myStats data format. I really like this app, Ive been using it around 2 years now. While it only gives two plot types in app, it allows an export as csv so you may analyze the data elsewhere in scipy, or any spreadsheet software you choose, which I prefer. Ive tried a lot of other personal analytics apps and this one is the most flexible and best suited for my needs. I do wish that you had the option of using a daily activity as timed activity as well without having to manually enter both. It would also be pretty great if you had the option to create categories in both timed and daily activities as well as unlimited amounts of activity adds. You may enter I believe around 100 activities as this time which is somewhat limiting; however, I wouldnt need so many if categories were allowed. I love that you have the option to track your evernote account in two ways. Easy to use interface. Great app, wish the dev would update their blog more often or play with it a bit more, however its stable so rather glad they dont.
