Lose Weight Without Dieting

“Lose weight without dieting” is the application motivating users to eat less, be active and lose weight. The application provides users with the food and exercise diary, charts of weight, body measurements and food values. The app is distributed in Google Play by “Freemium” scheme: a free “Lite” version and a “Pro” version. An interesting feature of the app is the variable price of the Pro-version in dependence on the amount of bonuses collected by a user. Bonuses are collected for each action potentially approaching the user to his goal, so the user is more involved in the application.
