Every time you start the app you have to enter the birthday. It gives you all the little statistics at once. Those are the two biggest flaws. The way the app is designed it is like the developers intended you to download it once for a day and then delete the app.
How they could have done it as a notification device. Simply have the app record your birthday and then every so often send an alert reminding you how many cat farts or whatever there will be until you die. They could also run the statistics for weight, heart, smokers and so forth. They could provide links to healthy living tips and the like. They could have done just about anything to make this better.
