data analysis, lack

have you ever see "A Plane" app in store? that have one part called "Data" you can define a name for example: book. when pressing on book you can ad parameter to it for example : page or duration then defining for it a unit, also you can leave it empt. you can assign any float number daily to it also you can manipulate every day, finally you can see them on a chart and this is better if adding it statistical info. and this is only what I need, but a plane not developing their app , it's chart is not really nice and it don't provide statistical info.
