Fasting App: Tracker & Timer

What it does

This is a health and wellness app designed to help users with intermittent fasting. It creates personalized fasting plans based on user goals and biometrics, provides a timer to track fasting windows, and includes tools to monitor related health habits like water intake and weight. The app also features an AI-powered wellness coach for support.

Where it shines

The app's greatest strength is its highly structured and motivational onboarding process. It transforms a simple quiz into a journey by asking for a specific motivating event, like a vacation (01:09). This data is then used to create a powerful paywall screen at 01:45 that frames the subscription not as a feature unlock, but as a concrete action plan to "Reach your dream weight of 55 kg by January 14, 2025." This direct link between user input and the value proposition is compelling. Another highlight is the main dashboard, which includes an interactive, checklist-style guide (02:44) to help new users learn the ropes without feeling overwhelmed.

UX highlights

Interactive Learning: The dashboard at 02:44 features a "Welcome to Fasting" module that guides users through educational content with a checklist, promoting active learning over passive tutorials.
Actionable Tooltips: The app uses informational icons (e.g., at 04:02 on the Current Weight card) that open modals with clear, concise explanations about concepts like 'Scale Weight' vs. 'True Weight.'
Contextual Friction: When a user tries to end a fast early (05:23), the app presents a motivational pop-up. This gentle friction encourages users to stick to their goals.
Clean Data Logging: The water intake logger at 03:29 is simple and intuitive, using a plus button to add predefined volumes and providing clear visual feedback as the glass icon fills up.
Comprehensive Settings: The settings menus (03:42) are well-organized, allowing users to easily adjust their daily goals, preferred units, and notification preferences.
Integrated AI Coach: The app provides access to an AI wellness coach (05:49) with suggested questions, making it easy for users to seek guidance and support without leaving the app.

Monetization & growth

The primary monetization strategy is a subscription, presented through a soft paywall immediately after the onboarding quiz (01:45). The app avoids offering a free trial, instead pushing for a direct subscription. The paywall cleverly frames the purchase as the key to the user's personalized action plan, capitalizing on peak motivation. It also uses social proof with before-and-after photos. Many core features, such as viewing fasting history (06:35) and detailed fasting stages (04:53), are locked behind the premium subscription, creating multiple upgrade prompts throughout the user experience.

Who it’s for

This app is designed for individuals new to or practicing intermittent fasting who are looking for a structured, goal-oriented tool to manage their weight and improve their health. The emphasis on education, personalized plans, and motivational coaching suggests it's particularly well-suited for users who need guidance and accountability to build and maintain healthy habits.

Notes & opportunities

The app does an excellent job of personalizing the initial experience. However, the first paywall at 01:45 appears before the user has had a chance to interact with the core tracking features. Moving this paywall to appear after the first or second completed fast might allow users to experience the app's value more deeply, potentially leading to higher conversion. Additionally, the app could enhance the fasting timer screen (04:36) by providing more context about the current fasting stage without requiring a tap-through to a locked screen.
