DeFit is a free Android app designed by DeFit Development for users who find it annoying to add activity records when developing apps. It's a third-party app that uses Google Fitness API and service. DeFit is not affiliated with the Google company and does not collect or store any user data, including name, photo, or email address on the server side.

With DeFit, you can easily add running activity records to the fitness database without hiring a runner or shaking the phone. You can also specify the running speed and/or steps of the activity. The app is easy to use, and all you need to do is log in to your fitness account, turn on the switch "Sync fitness data," and check the status of the latest sync and remaining time.

DeFit is an excellent app for developers who want to automate their app testing process. However, users must take full responsibility when using DeFit for any purpose other than software development.
