Happy Scale might be a popular app for tracking weight, but it's currently unavailable to download on Android phones. Unlike typical weight-recording apps, Happy Scale utilizes behind-the-scenes technical analysis and predictive algorithms. Instead of focusing on comparing weight data from different dates, the app records weight trends and patterns to highlight the user's overall progress. This allows the app to not only display a person's weight history, but also the expected time-frame of when they could reach their goal, providing extra motivation in the process. While the availability is limited to iPhone users, there are some Android app alternatives that offer a similar experience.
