RP Diet Coach & Planner

What it does

RP Diet Coach & Planner is a nutrition app designed to create science-based, personalized diet plans. It guides users through a detailed questionnaire to understand their goals, whether fat loss, muscle gain, or maintenance. The app then generates a plan focused on macronutrient targets, aiming to provide a structured approach to eating for specific fitness outcomes.

Where it shines

The app's strength lies in its structured and data-driven onboarding process. It skips fluffy feature tours and immediately dives into personalization. The quiz feels thoughtful, breaking down complex topics into manageable steps. A standout moment is the body fat percentage selector (01:23), which uses illustrations to help users make an informed estimate, a much friendlier approach than a blank input field. Another highlight is the interactive goal-setting screen (01:26), where users can toggle between different diet paces, instantly seeing how their end date and target weight are affected. This builds a strong sense of ownership and understanding before they even see the paywall.

UX highlights

Focused Onboarding: The flow is linear and purposeful, dedicated entirely to gathering the necessary data for a personalized plan.
Visual Estimation Tools: At 01:23, the app uses body type illustrations to help users estimate their body fat percentage, reducing friction on a difficult question.
Interactive Scenarios: Instead of asking users to set a vague goal, the app presents concrete scenarios like "Highest success" and "Slow & steady" (01:26), making the choice more meaningful.
Progressive Disclosure: The quiz is broken into multiple screens, preventing the user from being overwhelmed by a single long form (00:40 - 01:26).
Clear Language: The questions are direct and easy to understand, avoiding overly technical jargon where possible.
Early Commitment: Placing mandatory account creation (00:05) at the beginning ensures that any user who invests time in the quiz is captured as a lead.

Monetization & growth

The app employs a hard paywall strategy, which appears at the very end of the onboarding quiz (01:38). There is no free trial offered, meaning the user must subscribe to proceed and see their personalized plan. The paywall presents two options: a monthly and a yearly membership, with the yearly plan highlighted as the "Best value." This approach relies on the detailed onboarding process to build enough perceived value and user investment to drive conversion without a trial period.

Who it’s for

This app is clearly aimed at individuals who are serious about their fitness and nutrition goals and are looking for a structured, data-driven plan. The emphasis on macros and the detailed quiz suggest a target audience that is likely already familiar with fitness concepts or is willing to learn. It’s for the user who wants a coach-like experience and is ready to commit to a plan, rather than someone looking for a casual calorie counter.

Notes & opportunities

While the onboarding is strong, the immediate, un-warmed App Tracking Transparency prompt at 00:01 could be jarring and may have a low opt-in rate. A simple warm-up screen explaining the benefit of allowing tracking could improve this. Additionally, the entire experience hinges on the user completing the lengthy quiz. For users with lower intent, this could be a drop-off point. Introducing a lighter, quicker path to a sample plan or feature preview might capture a wider audience, though it would dilute their current focused strategy.
