MadMuscles: Workouts & Diet

What it does

MadMuscles is a mobile fitness coach that generates personalized workout plans for users. It begins with an extensive onboarding questionnaire to understand an individual's goals, from muscle gain to weight loss, and tailors a program based on their current fitness level, available equipment, and physical metrics like height, weight, and age.

Where it shines

The app's greatest strength is its onboarding, which masterfully builds a sense of deep personalization. The process feels more like a consultation than a generic quiz. For example, the interactive fitness level slider (00:17) provides a tactile way to self-assess. The most impressive moment is the mid-quiz summary screen (00:47), which recaps the user's choices, making them feel heard and invested long before the flow ends.

UX highlights

Interactive Data Entry: Instead of static forms, the app uses engaging inputs like a slider for fitness level (00:17) and visual selectors for target body areas (00:22).
Live Feedback: When entering weight (01:10), the app calculates BMI in real-time, providing immediate educational value and context.
Progressive Disclosure: The "We're halfway there!" summary (00:47) breaks up the long quiz, shows progress, and reinforces the user's commitment.
Clear Visuals: The app uses clean illustrations to represent goals, body types, and target muscle groups, making choices quick and intuitive.
Contextual Warm-ups: Before the system notification prompt, a well-framed warm-up screen (00:50) explains the benefit of enabling alerts.
Anticipation Building: The "Creating your personal plan..." animation (01:32) uses scrolling testimonials to build social proof while the user waits.

Monetization & growth

Monetization is handled through a hard paywall presented immediately after the personalization process is complete (01:46). The app doesn't appear to offer a free trial. Instead, it relies on the user's investment in the lengthy onboarding quiz to drive conversion. By the time the user sees the pricing, they have already spent several minutes providing detailed personal information and are likely curious to see the resulting plan. The paywall presents four options: 1, 3, and 6-month subscriptions, plus a lifetime access plan, with discounts highlighted to encourage longer commitments.

Who it’s for

MadMuscles seems to be for individuals who are serious about starting a structured fitness journey but may not know where to begin. The detailed quiz appeals to users who want a plan that feels scientifically tailored to them, rather than a one-size-fits-all program. It caters to both at-home and gym-based users and seems primarily targeted at men, given the visual assets used throughout the flow.

Notes & opportunities

The onboarding is long, which could be a point of friction for impatient users. While it builds investment, its length might deter some from completing it. A small opportunity could be to allow users to save their progress. Additionally, after providing so much data, the final plan summary screen (01:43) is quite brief; offering a slightly more detailed preview of the plan (e.g., sample exercises) could potentially increase conversion at the paywall.
