Fitness debt app as a gamified way of keeping track of your energy consumption versus expenditure ratio. Your friends keep you accountable and motivated to maintain your optimal daily ratio.
You owe it to yourself to burn every calorie you consume. The calories you don't burn are seen as debt that you eventually have to make up for. If you don't, you gain weight.
A gamified way of losing weight.
A way for friends to keep each other accountable and adhere to their fitness goals.
An app that keeps track and learns to predict your daily caloric intake and expenditure. It's paired with a device that monitors your heart rate, which helps it calculate your energy expenditure.
Guestimate caloric intake
The app relies on you logging everything you eat. You input the type of food and approximate quantities for every meal or snack. When logging your food, you can:
Input the total calories if you have that info
input the total quantity and the list of ingredients and guess the ratio between them
Input the food + weight (150g chicken, 100g potatoes, 50g lettuce)
If your goal is to loose weight the app will try to motivate you to burn more calories than you consume. If your goal is to maintain it, the app will warn you if you burn more than you consume.
Everyone has a profile where your friends (or evryone if you want) can see your daily caloric intake and expenditure. People can comment on each other's meals and activity graphs.
The app tries to get you to keep a streak of days with optimal caloric consumption to expenditure ratio.
Everyone's list of friends is arranged like a hall of fame. The person that keeps the longest streaks of optimal days is shown on top.
What else could be a good way to gamify the concept and keep people motivated?
