One-liner
A simple, no-frills heart rate monitor app that displays real-time BPM and frequency data using the phone's camera.
Strengths
- Accurately measures heart rate using the front-facing camera (confirmed in multiple reviews)
- Minimalist interface with clear BPM display and real-time frequency graph
- Lightweight and fast—no unnecessary features or ads
- Works reliably on a range of devices (iPhone 8+ and newer, some Android models)
- Highly rated for consistency in readings compared to other free apps
Weaknesses
- Only works with front-facing camera—no rear camera support
- Users report inconsistent results when moving or in low light ("Doesn't work if I move my hand at all")
- No historical tracking or data export ("I want to save my readings but can't")
- No calibration or user input for resting heart rate
- Limited customization—no option to change units or graph style
Opportunities
- Add offline data logging and export (CSV/HealthKit) to appeal to fitness users
- Introduce ambient light detection and motion compensation to improve accuracy
- Support rear camera for use with hands-free mounting (e.g., on bike handlebars)
- Add basic trend analysis (7-day average, min/max) without overcomplicating UI
- Offer a Pro version with sleep tracking or integration with Apple Health
