Slimming World

What it does

Slimming World is a digital weight management program designed to help users adopt healthier eating habits and lose weight. Based on the video, the service starts with a comprehensive personal and medical data collection process to create what is implied to be a tailored plan for its members.

Where it shines

The app's onboarding process stands out for its responsible and consultative approach. Instead of a generic sign-up, it walks the user through a detailed questionnaire covering everything from basic demographics to sensitive health conditions. The most notable moment occurs at 00:53, where the app calculates the user's BMI and halts the registration process because the user falls into a healthy weight category. This ethical gating is a powerful differentiator in the health and fitness market.

UX highlights

Linear, step-by-step flow: The onboarding quiz breaks down a long form into manageable, single-focus screens, reducing cognitive overhead for the user.
Clear data input: The app uses native iOS pickers for dates and measurements (00:13, 00:30), which are familiar and easy to use.
Helpful inline validation: The app provides immediate feedback for potential issues, such as the warning for an unusually low weight at 00:35 or for mismatched emails at 03:12.
Focused UI: The design is clean and utilitarian, keeping the user focused on the task of data entry without distracting visuals or animations.

Monetization & growth

The app's monetization strategy appears to target high-intent users. The entire sign-up and data collection process, which takes several minutes, occurs before the paywall is shown at 03:46. There is no free trial offered. This creates a hard paywall, meaning users must subscribe to access the service. This approach filters out low-intent users and ensures that only those who are truly committed to the program and have invested time in the setup process see the payment screen.

Who it’s for

Based on the detailed questionnaire and serious tone, Slimming World is for individuals who are genuinely committed to a structured weight loss journey. The emphasis on medical conditions and responsible gating suggests it targets users looking for a credible, safe, and supportive program rather than a quick-fix or casual calorie counter.

Notes & opportunities

The transition from the native-feeling app shell to what appears to be a web view for the sign-up process (around 00:03) can feel a bit disjointed. While functional, a fully native experience could feel smoother. Additionally, the onboarding flow lacks any social proof, like testimonials or star ratings, which could be an opportunity to build trust earlier in the process, especially given the amount of personal data requested.
