Since I joined uni in London, I’ve fell sick a few times.
I have this habit of logging my temperature (something from my family) so its easy to report to a GP, and easy to remember when you last had medicine.
I have been using Google Keep as this scrongled way of logging my temperature, but that seems a bit inconvenient; So I look around Google Play Store — and nothing much (in 2019).
Then I remember this isn’t my first rodeo with fevers, and I had been working on vitals-recorder
to log temperatures.
Here it is – https://bd.kekvrose.me
It was incomplete, with quite unusable issues, so I went on to complete it. Atleast the smallest bit of it. Try it out maybe!
What’s the thing?
Well, its to track your temperature, as and when you need. It can also log BP, sugar levels, SPO2 (in case you have that kind of fever) and a small description. I usually just log any pills I’ve taken at that time.

Very simple to add and edit. Plus, if you don’t like Fahrenheit, you can seamlessly use Celcius instead.

As visible, you can also export this data out as JSON, if you decide you want to use something else. The format is not too complicated to wrangle, and its documented here – Items.ts. The JSON is an array of items.
Completely offline
Well, the best part is this “app” is that its a PWA. This means it will work offline from the time you first open the website, and you can “install” it on your phone/desktop and it will function similar to a “native” application.

The data’s all stored locally (IndexedDB) and never leaves your device. In fact, since its completely local, there’s no server side processing and its hosted completely on Github Pages.
Summing it up
Well, here’s a nifty tool in case you want to log any vitals. Feedback is always great to have, so do try it out and let me know!
