BMI Rechner – Gewicht Tracker
Calculate your BMI, track your weight, and stay motivated together. Start without an account.
About BMI Rechner – Gewicht Tracker
Calculating your BMI takes three seconds – sticking with it is the hard part. This BMI calculator turns a single number into a progress chart that you can actually track.
CALCULATE YOUR BMI – INSTANTLY, NO REGISTRATION REQUIRED
Enter your height once, then just your weight. You'll see your BMI, your normal range, and where you fall on the scale. No account needed to get started.
CLASSIFICATION: BMI FOR WOMEN, MEN, AND BY AGE
The WHO guidelines apply equally to women and men – what differs is body composition. And with age, the optimal range shifts upwards. The app explains both in a dedicated section, with age-related guidelines and the complete WHO classification.
YOUR ARCHIVE, NOT JUST A VALUE
Every entry is saved. The progress chart shows the daily values as well as the 7-day average, so normal fluctuations don't throw you off track. With an account, your data is stored in the cloud – log in with your email address and everything is available again, on any device.
GOAL AND REALISTIC FORECAST
Set a target weight. You'll see how much you still need to lose, how much your weight changes on average each week, and when you'll reach your goal at this pace.
TOGETHER INSTEAD OF COMPETING WITH EACH OTHER
Connect with your partner, a friend, or your nutritionist. You'll see your progress side-by-side – but nothing is compared or ranked. Everyone pursues their own goal. The shared weekly goal isn't "who loses more weight," but "we both log our progress."
YOU DECIDE WHAT OTHERS SEE
Connecting someone doesn't automatically reveal your weight. For each connection, you choose: progress percentage only, history only, or full data. Any sharing can be revoked with a single tap – even retroactively. Weight gain is not reported to anyone.
A REMINDER THAT FITS LIFE
A weekly reminder on the day and time you choose. Consciously weekly instead of daily: daily weigh-ins primarily measure water weight, not progress.
