How it works
Two people. One agreement. One goal.
Diet Bond is a weight loss challenge for two. Here's the whole journey, from the first invite to the final reward.
Step 1
Pick your roles and invite your partner
Both of you create an account with your phone number, which is verified with a six-digit code. Then one of you starts an agreement and chooses a role.
- The Dieter
- The person who wishes to lose weight. The Dieter logs meals, exercise and weight, and works towards the target.
- The PT
- The person who helps, supports and motivates the Dieter. No qualifications needed: “PT” stands for personal trainer, but in Diet Bond it means the partner who's in your corner.
Invite your partner by phone number, typed in or chosen from your contacts. If they haven't joined Diet Bond yet, the invitation waits until they sign up with that number.
Step 2
Write the agreement together.
The agreement is the heart of Diet Bond. It captures everything you're committing to, so there's no confusion about the plan later.
- About the Dieter — height and activity level, from sedentary to vigorously active
- Diet targets — current weight, target weight and the weeks to achieve it
- A starting photo — so the before-and-after is there when you need it
- Meal schedule — times for breakfast, morning snack, lunch, afternoon snack, dinner and night snack
- Four rewards — weekly and final, from the PT to the Dieter and from the Dieter to the PT
- A personal message — sent with the invitation to your partner
Your partner reviews the details and accepts. Agreements can be edited later if your plans change.

Before you commit
An honest check on your goal.
Crash targets set you both up to fail. Once you've entered your targets, Diet Bond rates how demanding the goal is.
The rating weighs up the weekly weight loss rate, the share of body weight you plan to lose, and the Dieter's age, sex, activity level and BMI. If the goal comes out as very hard or extremely hard, the app recommends going back and adjusting it.
Diet Bond is an accountability app, not medical advice. If you have a health condition, talk to a doctor before starting a diet.
- Requires commitmentYou are good to go! Start your Diet Bond journey!
- Strong commitmentAchievable, but needs a strong commitment from the Dieter and the PT.
- HardHard to achieve. Needs a permanent commitment from you both.
- Very hardWe recommend going back and adjusting your goals.
- Extremely hardWe recommend going back and adjusting your goals.

Upload Your PhotoStep 3 · Every day
Log meals, exercise and weigh-ins.
The Dashboard shows today's meals at the times you scheduled, your exercise, and your weight progress towards the target. Each log can include a photo, a description and a note for your PT.
“How did you behave?”
Every log asks for an honest self-rating:
Very Good
Good
Okay
Not Good
Bad
Step 4 · The PT's side
Support that shows up.
Every log the Dieter saves is posted to your private chat automatically, so the PT never has to ask how the day went.
- The PT sees the Dieter's meal, exercise and weight logs while the agreement is active.
- The PT can view logs but can't edit them. The Dieter's record stays the Dieter's.
- Logs aren't shared until the agreement has been accepted.
- Notifications for new weight logs, meal messages and rewards can each be switched on or off.
Step 5 · Every week
A target for every week.
Your final goal can feel far away. Diet Bond breaks it into weekly targets on a straight line from your starting weight to your target weight.
At the end of each week, your last weigh-in is compared with that week's target. At or below it? The week is Achieved and the weekly rewards are earned. Above it? The week shows as Not Achieved, and next week is a fresh start.
| Week | Weekly target | Last weigh-in | Result |
|---|---|---|---|
| 1 | 81.4 kg | 81.2 kg | Achieved |
| 2 | 80.8 kg | 80.9 kg | Not Achieved |
| 3 | 80.1 kg | 80.1 kg | Achieved |
| 4 | 79.5 kg | 79.4 kg | Achieved |
