ダイエットバトル - 友達と競って痩せる

■ Why you can't stick to a diet alone isn't because you lack willpower.

No matter how many times you say, "I'll get serious tomorrow," if you're the only one watching, you can slack off and no one will notice.

Diet Battle is a competitive diet app where you compete with friends based on weight fluctuations.

Simply enter your weight daily to update your ranking, and you'll receive a notification if you're overtaken.

Creating an environment where you can't slack off is the quickest way to succeed.

■ How to Play is Easy

1. Create a Battle
Decipher the duration (1 week or more, as you like) and the penalty for the last-place finisher.

"The last-place finisher has to treat everyone to yakiniku (Japanese BBQ)"—that alone will get everyone serious.

2. Invite Friends
Simply send a 6-digit invitation code. They can join immediately.

3. Record Your Weight Daily

Your ranking is calculated the moment you record, and everyone's ranking is updated.

If you don't enter your weight on a particular day, the previous day's weight is carried over, ensuring fairness.

4. Waiting for the Day of the Showdown
The results will be announced when the period ends. The winner will be awarded, and the last place finisher will face a penalty game.

■ Two Ways to Compete

- Compete by Percentage Loss: How much weight did you lose compared to your starting weight? You can compete fairly with friends who have different weights.
- Compete by Weight Loss (kg): A simple competition to see who can lose the most kilograms.

Furthermore, a handicap function allows for a more even competition even if there are differences in ability.

■ Features to Keep You Going

- Timeline: Share photos of your meals and declarations of your exercise with your friends. Get excited with reactions and comments!
* Reversal Meter: Always shows how many more kilograms you need to move up in rank.
