What it does
90 Day Challenge is a fitness application designed to guide users through a comprehensive body transformation. The app creates personalized workout and nutrition plans based on an initial in-depth quiz. It functions as a daily companion for logging workouts, tracking habits like water and sleep, and exploring a library of recipes and fitness knowledge.
Where it shines
The app excels at creating a structured, goal-oriented experience. The onboarding quiz (00:19 - 01:27) is thorough, building user confidence that the resulting plan will be truly personalized. The in-workout logging is another highlight. For each exercise, users can input weight and reps (03:59), and the app provides instant feedback with a trend arrow, making progress tangible and motivating. Finally, the gamification of daily habits through collectible badges (06:03) makes consistency feel rewarding.
UX highlights
- The app immediately shows 'Before & After' photos on its welcome screen (00:03), providing a powerful and instant demonstration of value.
- The workout interface is clean, providing access to instructional videos and a simple system for logging performance for each set.
- After a workout, the app generates a shareable 'Day Streak' image (04:41) and a workout summary, encouraging social proof and organic marketing.
- The habits tracker (05:49) is simple and effective, using checkboxes and plus/minus controls to make daily logging fast.
- Users can view their weight and exercise progress through clear, easy-to-read charts (12:54, 13:39), closing the feedback loop on their efforts.
- The app includes a 'University' section (10:18), offering a library of educational content that adds value beyond just workouts.
Monetization & growth
The app uses a hard paywall strategy, requiring users to subscribe after the extensive onboarding quiz but before accessing their personalized plan (01:53). It presents two subscription options (Yearly and 90 Days), with the yearly plan highlighted. The pricing is broken down into a weekly cost ('$1.90 PER WEEK') to make the commitment seem smaller. The subscription is initiated through a standard 1-week free trial, which is a common and effective way to lower the barrier to entry.
Who it’s for
This app is geared towards individuals who are committed to a structured fitness journey and appreciate detailed tracking. It seems ideal for beginners to intermediates who need guidance and a clear plan to follow. The emphasis on both workouts and nutrition makes it suitable for users looking for a holistic approach to fitness, whether their goal is to lose weight, build muscle, or both.
Notes & opportunities
The onboarding quiz is very long, which could lead to some user drop-off. While it builds a sense of personalization, testing a shorter version might be worthwhile. The app introduces 1-on-1 coaching via a prominent banner (03:05), but this could feel a bit like an upsell immediately after a user has just subscribed. Delaying this offer until the user has completed a few workouts might feel more natural. Finally, the app could enhance its social features by allowing users to share their badges or weekly progress, not just single workout summaries.
