Achievement

Achievement is an app that lets users earn money by contributing to different kinds of health-related research projects.

On Achievement, you can answer surveys and questionnaires, provide data on your habits, and participate in various health-related research projects that may later be published in prestigious journals on an international level. When you open the app, you can do one of two things: answer questionnaires, each of which rewards you with a certain number of points upon completion, or connect the app to health apps like Google Fit, Apple Health, and Fitbit, among many others.

From the questionnaire section, you can see each available option and how many points it's worth. You can also see how long it usually takes to finish each questionnaire. Once you've answered all the questions, you'll get the points you were promised. Likewise, if you connect Achievement to other health tracker apps, you can upload data on your habits to the app, including the number of steps you take per day, the calories you consume, and your sleep log. The points you get for completing these actions can be redeemed for real money.

With Achievement, you can participate in health studies and even earn money for doing so. The app also has a clean and elegant design, which is always appreciated.
