LogMyBP is a tiny (arguably toy) app I built to help my parents keep track of their blood pressure readings. Following an episode, one of my parents needed to log readings three times daily, in three different positions. At first they did it on paper, then a gsheet. Seeing as how my folks aren't the most computer-literate, I was doing a lot of tech support to help set up and maintain this gsheet template. Naturally, I decided to over-engineer a solution.

LogMyBP is intended to help my parents, who can use a web browser, email, and a smart phone just fine, but get frustrated when creating accounts, remembering passwords, or installing apps. This requires none of that - they just have to put in their email address and readings, and the app takes care of recording and retrieval. It does so by creating an "account" using their email address on the fly, and lets them verify and reuse it with an emailed magic link. Once logged in, they can export their readings to a formatted text file for printing, or a CSV file to open in sheets or excel and bring that to the doctor. I also tried to keep the UI descriptive, high contrast, and very simple.

Technical bits: I decided I'd build this quickly with the help of an LLM, just to see how far I'd get. ChatGPT did a great job, but I'm enjoying Claude Sonnet as of now. It's a Python, Flask, Tailwind, and SQLite app, running on Fly.io. ChatGPT and Claude are really good at Python, as well as HTML templating. I suck at the latter, and they saved me a ton of time. I also attached a self-hosted version of Plausible since I wanted to learn how to do that vs use 3rd party telemetry.

Feel free to play around with it.
