How it works

Your weight loss challenge in three steps

No account, no spreadsheet, no maths.

1

Create a challenge

Pick a name, a start date, a length of 4 to 16 weeks and a weigh-in day. Takes a minute.

2

Share the link with your group

Everyone joins with the link, in the app or right in the browser. Just a nickname and a starting weight.

3

Weigh in and attack

Enter your weight on weigh-in day, check your place, win your duel. The leaderboard does the maths.

Features

Everything that makes a challenge exciting

A new race every week, not just a result at the end.

  1. Leaderboard by percentage

    Ranked by change from the starting weight. Everyone has the same shot at first place.

  2. Weekly winners

    Every week, whoever achieved the most since the last weigh-in wins the week. Even from 7th place.

  3. Duels

    You against the person right ahead: the gap, both trends and what it takes to overtake by the next weigh-in.

  4. Badges and records

    Streaks, best week, comeback, held the lead. Plus your personal records.

  5. Cheering

    Reactions to weigh-ins and place changes, plus the group feed “This week”. No comment threads.

  6. Daily weigh-ins, private

    Log every day if you like. Only you see the trend and where you would stand if today were weigh-in day.

Duel of the week

Who overtakes whom by Monday?

Lossboard shows who you are up against right now and how close it is. When you pass someone, the whole group sees it in the feed and can cheer you on.

FAQ

Frequently asked questions

How much does Lossboard cost?

Nothing for up to 3 people. For up to 10 people the organiser pays €4.99 once, for up to 30 people €9.99. If you organise more often, the organiser year is €19.99. Participants never pay. No subscription, no ads.

How is the winner decided?

Lossboard ranks the percentage change from each starting weight. That gives everyone the same shot at first place, whatever weight they start at. Try it in the percentage calculator.

What is the weekly winner?

Every week, whoever made the biggest change since the last weigh-in day wins the week. So someone in the middle of the table can celebrate too. Ties give several weekly winners.

How do duels work?

You automatically face the person right ahead of you. Lossboard shows the gap in percentage points and works out from your own weight how much it takes to overtake by the next weigh-in day.

Does everyone need the app?

No. Anyone who does not want to install it joins in the browser, enters their weight there and sees the leaderboard, their duel and badges.

Who sees my weight?

Everyone in the challenge knows what it is about: by default the group sees your change in percent and in kg. With “Hide my kg” or “Hide my values” you can switch that off at any time. Only you see your daily entries. No account and no email address needed. More in the privacy policy.

How often do I weigh in?

The leaderboard uses the weekly weigh-in day. If you like, you can also weigh in daily: only you see those entries, with your trend and the place you would hold if today were weigh-in day.

Who is Lossboard for?

For adults 18 and over who want to run a weight loss challenge with friends, family or coworkers. Lossboard does not replace medical advice.
