# BP Lens

> Take 3 photos of your blood pressure monitor and BP Lens reads the numbers, saves the average and explains your level in plain words. iPhone app. Not a medical device.

BP Lens is an iPhone blood pressure diary by Ingeniería.dev (Chris Flores, https://ingenieria.dev). The user measures
3 times with their own home monitor and photographs the screen after each reading; BP Lens reads systolic, diastolic
and pulse, saves the average with its informational 2017 ACC/AHA category, and shows history, trend and a report every
3 days. Version 1.1.0: optional Apple/Google account with encrypted backup, and a private 30-minute link (or MCP
connector) so the user's own AI assistant can read their history. Not a medical device.

## FAQ
- **Which monitors does BP Lens read?** Any home monitor with a digital screen showing systolic, diastolic and pulse. If a photo is blurry or a number looks off, you can correct it before saving, or enter the reading by hand.
- **Why three readings?** Home blood pressure guidelines (AHA/ACC 2017, ESH 2023) recommend at least two readings in a row and using the average. BP Lens makes three effortless and averages them for you.
- **Is it a medical device?** No. BP Lens is a diary with informational categories. It does not diagnose or treat, and it never replaces your doctor. In an emergency, call your local emergency number.
- **Do I need an account?** No. Everything works without one. An optional Apple or Google sign-in adds an encrypted backup so you can restore your history on a new iPhone.
- **What happens to my photos?** Only with your consent, the three photos are sent to our server to read the numbers. They are not kept there. Your records and your profile stay on your iPhone.
- **Does it work with Apple Health?** Yes, if you turn it on. Your readings can be saved to Apple Health and BP Lens can read your past ones.
