Build a cardiac health tracking app
A 73-year-old with no coding experience built an app with Claude to track blood pressure, fluid, weight, heart rate, symptoms, meals and activity after a hospitalization.
Done withClaude
- What they did
- After a November 2025 hospitalization for dehydration, the poster started with a spreadsheet and then used months of back-and-forth with Claude to turn it into ClinBridge, a progressive web app for tracking blood pressure, fluid intake, weight, heart rate, symptoms, meals, and activity. He says Claude helped build and word the project, while he decided the requirements; the app installs on a phone, works offline, and keeps data on the device.
- How it went
- He says the app reached version 9.9.25 over about five months, is free and open source, and was built to help him avoid another preventable episode. The thread’s main shortcoming is trust: many commenters doubted the story, though some who inspected the code said the app itself looked real and non-malicious.
- Worth knowing
- He says the only ongoing costs he wanted help offsetting were the domain and his Claude subscription.
Try it yourself with Claude
Help me build a simple app, step by step and with no coding assumed, to track [blood pressure, weight, fluid intake, heart rate, symptoms, meals, activity] after [my condition or hospital stay]. It should let me enter daily numbers easily on my [phone or computer], show simple charts, and make a printable summary for my [doctor] visits. We're done when I can enter today's readings and see the chart. Remind me it does not replace medical advice.
