Weight Loss Challenge App

Turn weight loss progress into a challenge you can share.

  • Track weigh-ins

    Enter weight manually or use supported connected health data.

  • Compare percentage change

    Rank progress relative to each participant’s starting weight rather than pounds alone.

  • Follow body metrics

    Track weight, body fat percentage and BMI over time.

  • Keep the group involved

    Use leaderboards, chat, photos and notifications to maintain engagement

    See challenge rankings and percentage change while the competition is active.

Weight Loss Competition Metrics

More than one way to measure progress.

Groups can focus on the body measurement that best fits the challenge, while activity metrics can provide additional context and ways to compete.

  • Weight Loss

    Compare percentage change from starting weight.

  • Body Fat %

    Compete on body fat percentage change when available.

  • BMI

    Track BMI change across the challenge.

  • Activity

    Steps, distance, move calories and exercise minutes.

30 Day Weight Loss Challenge

Build a challenge around a clear start and finish.

A 30 day weight loss challenge gives a group enough time to establish a routine while keeping the finish line close enough to stay visible. Strive also supports other date ranges, so you can choose the duration that works for your group.

  • Family weight loss challenge

    Create a private challenge for people you know.

  • Workplace groups

    Run weight loss challenges as part of an employee wellness program.

  • Privacy-aware competition

    Challenge results can focus on percentage change instead of exposing a participant’s actual weight.

Track • Compete • Connect

Keep a weight loss challenge visible between weigh-ins.

  • Track your trend.

    Review measurements across week, month and year views instead of reacting to a single weigh-in.

  • Compete on progress.
