Build a cardiac health tracking app
Community report: 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. He says the app reached version 9.

Why it matters
Coding agents are moving from autocomplete to doing whole tasks: reading a codebase, making a plan and changing many files. This case is a concrete example of where that works in practice. It is one of 106 sightings filed under Software Development on Agent Sightings (number 7 by interest), and one of 91 involving Claude.
How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into Claude or any similar agent and adjust the details to your situation.
In this repo, build a cardiac health tracking app. Read relevant code, apply a minimal patch, run available checks, and summarize the diff. Stop before merge or deploy.
The prompt breaks down into 3 steps you can check as the agent works:
- In this repo, build a cardiac health tracking app.
- Read relevant code, apply a minimal patch, run available checks, and summarize the diff.
- Stop before merge or deploy.
Tip: Work on a fresh branch, ask for a plan before edits, and review the diff and test results before merging.
