Wellmy - Heart Rate Monitor

What it does

Wello is a health monitoring app that turns a smartphone's camera and flash into a tool for measuring vital signs. Its core function is to measure a user's heart rate. Based on that measurement, it also calculates and displays other key health indicators such as blood pressure, HRV (Heart Rate Variability), stress, and energy levels.

Where it shines

The app excels in making a potentially tedious process feel engaging. During the heart rate measurement, instead of just a progress bar, the app displays interesting biological facts (01:15), which helps the time pass quickly. The results dashboard (02:39) is another strong point. It presents a clean, high-level 'Health Balance' score, with individual metrics like Blood Pressure shown in a simple, color-coded format. This design avoids overwhelming the user with data upfront.

UX highlights

Focused Onboarding: The initial flow uses a multi-screen carousel (00:23) to clearly explain its core benefits one by one before asking for a commitment.
Engaging Wait Times: The app smartly uses fun facts to fill the measurement period, transforming a passive wait into a moment of light discovery (01:21).
Progressive Disclosure: The main dashboard presents key data simply, but each section has a 'more' button (02:51) that reveals detailed explanations, catering to both quick glances and deep dives.
Clear Data Visualization: The daily statistics screen uses a simple bar chart (03:21) to show trends for Health Balance, Stress, and Energy, making progress easy to understand.
Always-on Core Action: The 'measure' button is persistently located at the top or bottom of the screen, making it easy to start a new reading from anywhere in the app.

Monetization & growth

Wello employs an aggressive but straightforward monetization strategy. It uses a hard paywall immediately after the onboarding carousel (00:32). All core functionality is gated, requiring users to subscribe to a weekly plan with a 3-day free trial to even perform the first measurement. The offer is presented on a summary screen and then through the native iOS payment sheet (00:38). There are no visible alternative plans or lifetime offers in this flow.

Who it’s for

The app is designed for health-conscious individuals who want a convenient way to track their daily vitals without needing a separate wearable device like a smartwatch. Its simplicity makes it suitable for anyone looking to get a quick snapshot of their heart rate, blood pressure, and stress levels, whether for general wellness, fitness tracking, or managing stress.

Notes & opportunities

The mandatory sign-up right at the start (00:07) introduces immediate friction, which could deter some users. However, asking for personal details like age and weight after the first measurement (02:17) is a smart choice, as the user is already invested and sees the reason for providing the data. The app could potentially improve permission opt-in rates by adding custom warm-up screens before showing system prompts for tracking (00:04) and notifications (03:19).
