The #1 Weight Loss Competition App!

Updated 10/20/2026

• Your weight loss percentage is calculated using your starting weight from the challenge and your most recent weight entry. Entries made before the challenge begins are not included.
• All weight loss percentages are calculated in kilograms (kg). If you enter your weight in pounds (lbs), it will be stored in kg, but displayed in lbs. Rounding during conversion may cause a slight difference (up to 0.01%) in your displayed percentage. Your ranking will not be affected, as the same calculation is used for everyone.
• Note: Your percentage of weight loss is only shown when you are competing in a challenge. 

• Your ranking and your percentage of weight loss in the competition will only appear after you've made 2 weight entries on 2 different days after the competition starts. For most people this will be the second day of the challenge or after your second scheduled weigh-in. 

• We take your earliest available weight and your last available weight within the challenge window to calculate your percentage of weight loss, so even if you joined a challenge late, you can still compete. 

• You can edit your weight throughout the day as often as you like, however, once the clock strikes midnight, you will no longer be able to edit your weight for the day. To keep the competition fair, you cannot go back to edit your weight for previous days. 
• And remember, your percentage of body weight lost will always be based on your most recent weight entry and the entry from the first day of the challenge. So if you happen to miss a weight entry or enter your weight incorrectly, simply enter your weight correctly the next day. 
• We recommend measuring your weight in the morning at around the same time everyday, with the same wardrobe for the most consistent results. 
• For any issues with your weight entry, please email: support@fit4friends.com.

• Yes, your weight and your weight log is only viewable by you. When you compete in a weight loss competition, only your rank in the competition and your percentage of weight loss is shared with your opponents. 
• If you would like to share a specific weight entry with your challenge organizer or other participants, you can do so by navigating to the Weight Log, selecting the calendar date of the weight entry you would like to share, then selecting share. 

• No setup needed! A group chat is automatically created when your organizer creates the challenge. Once you’re added to the challenge, you can join the conversation and view previous messages.

• You can send messages from the time the challenge is created until seven days after it ends. During this seven-day grace period, the challenge stays on your homepage so you can celebrate your progress and wrap up conversations.
• After the grace period, the challenge moves to the Past Challenges section of the app, and its group chat becomes view only. You can still read previous messages, but you can no longer send new ones.

• Yes! Message your Connections anytime, or any challenge participant (including the organizer) from the time of challenge creation until seven days after it ends. Simply open the challenge chat, tap Send a Direct Message, and select a participant.
• After that, direct chats become view only unless you’re in connection. To keep chatting, send a connection request—once accepted, you can message again!

• Yes! You can compete with friends and family anywhere in the world. Challenge start and end times are based on the Challenge Organizer's time zone. Challenges end at 11:59 PM on the selected end date in the organizer's time zone, but each participant will see the deadline adjusted to their own local time.
• For example: If the organizer is in New York and the challenge ends at 11:59 PM, a participant in Los Angeles will see the deadline as 8:59 PM that same day.

• Within the app, challengers have the ability to upload images of their scale for proof of their weight. For documentation, we recommend taking a picture of the scale after stepping off. You can then share this image with the Challenge Organizer and/or your competitors. 

• No, after you accept a challenge invitation, you must contact the Challenge Organizer to be removed.  Please note, if you are the Challenge Organizer, you cannot remove yourself directly from a challenge, instead you must delete the challenge prior to the challenge start date.
