TrendWeight v2 Has Launched!

After more than a decade sitting mostly unchanged, TrendWeight has gotten a fresh update. While the app looks and works mostly the same way you're used to, everything under the hood has been modernized.

What You Need to Know

Logging In

You'll need to log in again using your email address. When you log in with the same email you used before, your existing account and all your data will automatically transfer over.

Don't remember which email you used? No problem—just create a new account and connect it to your Withings or Fitbit account. TrendWeight will load all your historical data from your scale.

Also note, the old site used to let you login with a username only (not an email). That isn’t possible anymore. In the interest of improving security, the new TrendWeight doesn’t use passwords and relies on one-time login links via email or using Google, Microsoft, or Apple logins.

What's New

Connect Multiple Scales

You can now connect both Withings AND Fitbit to the same account. If you switch scale brands, there's no need to worry about losing historical data—just connect both and TrendWeight will combine everything into one continuous chart.

Better Mobile Experience

The weight charts on phones now show more than just the last 4 weeks. You can finally see your longer-term progress without switching to a computer.

Easy Data Export

Want to analyze your data in Excel or another app? There's now a simple way to download all your weight data from the settings page.

What's Gone

The chart image sharing feature has been removed since it was rarely used. Though you can still share a link to your dashboard with others—you'll find your sharing URL in the settings.

Technical Note

For those interested, TrendWeight is now open source. You can find the code on GitHub or read about the saga at Rebuilding TrendWeight.
