Frequently asked questions

Diet Bond is a weight loss app for two. One of you is the Dieter, the person who wants to lose weight. The other is the PT, the partner who helps, supports and motivates. Together you sign an agreement with a target weight, a timeframe, a meal schedule and rewards, then track the plan week by week in the app.

No. In Diet Bond, “PT” is a role, not a qualification. Your PT is your partner: the person who checks in on your logs, replies to your messages, cheers you on and keeps their side of the reward deal.

Diet Bond is designed around couples, so your love partner is the natural choice. In the app you invite your PT by phone number, either typed in or picked from your contacts.

Yes. Either partner can create the agreement. You choose your role first (Dieter or PT), then invite the other person to review and accept it.

Yes. Diet Bond is built for two accounts. If your partner hasn't signed up yet, the invitation waits for their phone number. Once they create an account, they can review and accept your agreement.

Diet Bond is a mobile app for iPhone and Android.

Your roles, the Dieter's height and activity level, current and target weight, the number of weeks to reach the target, a starting photo, times for up to six daily meals (breakfast, morning snack, lunch, afternoon snack, dinner and night snack), four rewards, and an invitation message to your partner.

Before you commit, Diet Bond rates your goal on a five-step scale, from “Requires commitment” to “Extremely hard”. The rating looks at the weekly loss rate, how much of your body weight you plan to lose, age, sex, activity level and BMI. For the two hardest levels, the app recommends going back and adjusting your goals.

Meals, exercise and weight. Each log can include a photo, a short description, how you think you behaved (Very Good, Good, Okay, Not Good or Bad) and a message to your PT. Logs also appear in your shared chat, so your PT sees them straight away.

While your agreement is active, your PT can see your meal, exercise and weight logs and your progress. Your PT can view your logs but can't edit them. Until the agreement is accepted, your logs aren't shared.

Diet Bond draws a straight line from your starting weight to your target weight across the weeks you agreed on. Each week has its own target on that line. If the last weight you log that week is at or below the target, the week is marked Achieved.

No. Diet Bond doesn't prescribe diets, meal plans or calorie targets. It's an accountability tool: you agree on goals and meal times, log what you actually eat and do, and support each other along the way.

Yes. In Settings you can switch between Kg & Cm and Pounds & Feet, and choose a 12-hour or 24-hour clock.

Yes. Diet Bond can remind you at your scheduled meal times. You can also choose which notifications you get: new agreements, new weight logs, meal messages and rewards.

Whatever you both agree on. As the app puts it: “A gift, an activity, a love reward? It is up to you both.” The PT's reward should be something the Dieter genuinely looks forward to, and the Dieter's reward should be something the PT likes.

Support takes effort. When the Dieter hits a weekly target, the Dieter rewards the PT for helping. That keeps the PT motivated to keep supporting all the way to the final target.

That week shows as Not Achieved in the Rewards tab, and you carry on with the next week's target. Every week is a fresh chance to earn the weekly reward.

No. Diet Bond is an accountability app, not a medical service. If you have a health condition, are pregnant, or plan a significant change to your diet, talk to a doctor first.

Conversations in Diet Bond are between the two partners in an agreement. Only members of a conversation can open it.
