BodyOK: Intermittent Fasting

What it does

BodyOK is a mobile app designed to help users practice intermittent fasting. Its core functions include a timer to track fasting and eating windows, a water intake log, and a weight tracker. The app aims to provide a structured approach to fasting by creating personalized plans based on user goals and health data gathered during an extensive onboarding quiz.

Where it shines

The app excels at making data logging both flexible and rewarding. A key strength is the ability to manually add past fasts (03:16), a forgiving feature that ensures data accuracy even if a user forgets to use the live timer. The statistics screen is also well-designed, providing clear weekly, monthly, and six-month views (03:08) that help users visualize their consistency and progress over time. Finally, the main fasting screen (02:14) is clean and focused, presenting the essential timer and water tracker without unnecessary clutter.

UX highlights

In-depth Onboarding: The app uses a comprehensive, 20-question quiz (00:01 - 01:25) to gather detailed information, making the subsequent plan feel highly personalized.
Strategic Social Proof: During onboarding, a screen with the app's high App Store rating appears at 00:27, right after sensitive health questions, to build trust at a critical moment.
Personalized Loading: The "Building your plan" screen (01:25) uses the user’s name and a dynamic checklist, enhancing the perception of a custom-tailored experience.
Clear Statistics: The stats tab (03:08) uses simple bar charts to effectively visualize fasting hours and a line graph for weight trends, making progress easy to understand.
Flexible Data Entry: The ability to add past fasts and log weight manually at any time provides great user control and accommodates for real-world usage patterns.
Tiered Customization: Users can change the app icon for free (05:17), offering a taste of personalization, while more extensive theme options are reserved for premium subscribers.

Monetization & growth

BodyOK's primary monetization strategy is a subscription model presented after the onboarding quiz. The first paywall (01:42) is a timed "Welcome Offer" with a significant discount (60% off) and a countdown timer to create urgency. It also leverages social proof through user testimonials with before-and-after photos. If the user dismisses this, they are shown a second, different offer—a "Summer Sale" (02:11). The app also prompts users to rate it (02:29) and share with friends (visible in settings at 05:05), indicating a focus on organic growth.

Who it’s for

The app appears to be designed primarily for individuals new to or looking for more structure in their intermittent fasting journey. The detailed onboarding, choice of beginner-friendly fasting plans (01:57), and straightforward tracking tools cater well to those who need guidance and motivation. The focus on weight loss as a primary goal suggests it's for users with specific health and appearance-related objectives.

Notes & opportunities

The onboarding quiz is very long, which could lead to high drop-off rates despite its personalization benefits. The app could test a shorter version or allow users to skip some non-critical questions. Additionally, while the statistics are clear, the premium-gated features for water, sleep, and mood tracking (04:18) could be previewed more effectively to better demonstrate their value before asking the user to upgrade.
