IntelliDrink is my first paid app in the AppStore. In this case the idea, concept, design and programming was done by myself.

It’s a blood-alcohol content (BAC) calculator which gives you a nice overview about your current BAC and how your BAC is going to rise or drop. Actually there are many apps like that in the store but nevertheless I think IntelliDrink is somehow special.

The main difference is that my goal was not to create a fun app. I wanted to create a serious app which gives you good results. I put a lot of effort into the calculation algorithm which core based on the the scientifically accepted Widmark formula. This formula takes many human characteristics into consideration but it does not consider how long you are drinking a drink, how your hungry feeling was when you had the drink and it does not consider how fast your absorption and resorption of alcohol is. That’s why most apps assume that you downed the drink when you entered it. And even worse they assume that you completely digested it which certainly has nothing to do with how it really works.

The algorithm of IntelliDrink takes all of these factors into consideration. It is a complex algorithm which result is visualized on a nice graph. So you can see how your BAC value is rising over time, when your peak is reached and when you are going to be sober again. You can scroll and zoom into the graph too.

Another nice thing is that you can change the drinks you had or even change your profile settings afterwards. The graph is recalculated every time. So removing drinks, changing their sizes or moment of drinking is possible at anytime.

The second difference to other apps is the quality. I wanted to release a really good looking and very usable app. So I put plenty of time in polishing the user interface making it easy to understand and giving it a valuable feel.
