Based on the user's current weight, height, body frame, gender and age, the app suggests an ideal weight and recommends the amount of time needed to reach that target. You have the option to change the suggested targets based on your own plans. By inputting your weight at regular intervals, the app helps you track your weight loss. It also has a function to calculate your daily calorie intake, BMI (Body Mass Index), percentage body fat, total weight loss, remaining amount of weight to be lost, average daily and weekly weight loss and overall progress.
✔ The app is easy to use.
✔ It indicates if BMI is under, normal or overweight and adjusts appropriately for age.
✘ The app does not warn you if unrealistic weight loss targets are set manually such as very low BMI and very rapid weight loss goals.
✘ There is no information on how the recommended calorie requirement is calculated.

Review: "A very simple app that logs and tracks weight loss/gain. Assess energy requirements needed to achieve target weight in a pre-defined period of time. Both target weight and time frame to achieve it can be set manually. There are no alerts even when setting weight goals that result in a very low BMI eg 14kg/m2 prompting some concern. Clinical safety: some risk, as there are alerts when setting low target weight." New Zealand relevance: ★★★★☆ Comments: "Allows user to individualize measurement settings. There is provision for measurements of weight and height to be set to metric units such as cm and kg, which are used in New Zealand."
Formal MARS Review
The formal app review is based on the Mobile App Rating Scale (MARS) developed by researchers at Queensland University of Technology, Australia.(1) It is designed to score apps on a few comprehensive dimensions — engagement, functionality, aesthetics, and information quality. Each dimension comprises several items which are rated on a 5-point scale from “1.Inadequate” to “5.Excellent”. Read more about the MARS scale.
The mean score is the mean of two independent reviewers' ratings:
