Poking around, I found out that Oura ring has a robust API, so I wanted to see what Claude Code could do with it. It took an afternoon of fiddling, but it seems to be a robust custom data board with about 4 years of data, that updates itself 3 times a day to a SQLite database. It runs on my Mac Mini home server.
\nI can download my CSV data from the data board, and I also set it up to run a monthly report that makes an Apple Note for me and files it away. I had it run monthly reports for the past 4 years, and it’s an excellent way to digest sleep data.
\nThe best part is a second page on the dashboard called the Correlation Explorer, where you can see how tag data affects your sleep. You do have to remember to add tags, late meals, massage, medication, sauna, vaccinations, etc., and you can start to see what is helping and hurting your rest. You can see the evidence on my board. On this note, my wife swears that a hot shower before bed helps you fall asleep faster. That’s the next test that will be tracked with tags. We shall see.
\nI know a lot of people don’t like A.I., but I’m still in awe of the things I can build with it. This is so far beyond my skill level. And the data analysis that I can now do is truly helping my sleep. The older I’ve gotten, the worse my sleep has been. I’ve increased my sleep by one hour per night just from the Oura ring data.
\nI like the Oura ring app, and they have their own web view that is really nice, but being able to customize what you want to see and how is pretty neat.
\nIf you have any trouble with sleep, I highly recommend using the Oura ring for 6 months or so, using tags, and figuring out what helps and hurts your sleep.

\nFor the curious, here are some technical details.
\nThe Stack Snapshot:
\nbetter-sqlite3 – synchronous API, ~23MB database holding ~4.4 years of history.The Data Pipeline:
\nPulls 16 endpoints from Oura’s v2 API on a 14-day incremental window per run. Deliberately skips heartrate and interbeat_interval – those would 10x the DB for no visible dashboard benefit, and can be backfilled later if HRV analysis ever happens.
INSERT OR REPLACE on the Oura-assigned document ID (with UNIQUE(day) constraints on daily tables). Re-running ingest is a safe no-op; late-arriving recomputes overwrite stale scores.raw TEXT NOT NULL column holding the entire API JSON. If I want to derive a new column later, I don’t need to re-pull the API – just run a query over the raw JSON. Full-fidelity audit log, zero lossy transformations.ingest_runs table (endpoint, start/end dates, status, doc counts, errors). Makes it trivial to see “did the 8am run land last night’s sleep yet?” – which I used twice this week.Scheduling:
\nlaunchd fires npm run ingest three times daily (8:00, 12:00, 16:00). The multiple fires exist because Oura’s detailed sleep endpoint publishes ~1–3h post-wake, so the 8am run catches the score, later runs catch the detail. A separate monthly launchd job fires on the 1st at 9:15am to produce a digest.
Inspired by @numericcitizen and his editor, I set out to use Vercel and build a custom Micro.blog editor for my 3 blogs.
\nI made a free (hobby) account at Vercel and then got to work in Claude Code. Told it what I wanted, and for the first try, it was pretty good. It took me about 4 hours working with CC to iron out all the kinks. The biggest problems were with the media folder, uploading photos, and making cross-posting work correctly. But we got through all the issues, and it is working very nicely.
\n![\"Auto-generated](\"uploads/2026/cleanshot-2026-01-28-at-21.51.392x.png\")
\nI can choose which blog to post to, and it automatically populates the media folder, cross-posting options, and categories. I can send it to MB as a draft or a post. I can save the drafts locally as a JSON file and/or download all files.
\nHats off to @manton for a nice API to work with, @numericcitizen for the inspiration, and Claude Code for the ease in making something like this, because it is way beyond my skill level.
\nI put the web app behind a password-protected splash screen, since it is custom to my blogs only. I can only imagine the havoc if someone nefarious got into this. There are other security measures I can deploy as well. Vercel has been easy to use and understand. Their hobby plan seems sufficient for now. Interesting note: Vercel has its own AI agent. Once you connect your GitHub account, it can send its own pull requests. I let it send a PR for adding analytics, and it worked very well. Kind of fun to watch it all take place over on GitHub.
\nI’m going to use this for a while and see if it sticks. It’s really not needed because there is such a nice Mac App for MB that this is not necessary, but it sure shows you the possibilities. One area where it may come in handy is on the road with just my iPad; I can use the Web App to post.
\nI think my next project may be making an iOS app.

But, in my opinion, this is what they are for. My coding skills are at a hobby level, and now I can code using English, and it’s really fast and really good.
\nToday, “we” made an online Cliff538 Status Board web app. Not a single mistake was made; it went very smoothly. The only changes were asking whether certain APIs allowed more information to be displayed, and cosmetic changes to improve the look. I have a spare iPad on my desktop that keeps the page up and refreshing for me. Overkill, I know, but it’s a hobby. It’s damn fun.
\nIt refreshes every 30 seconds, runs locally on my Mac Mini, and is accessed using Tailscale.
\nI love it.
\nI can see more custom apps in my near future. This really cements the purchase of the Mac Mini as a home server; this web app running locally hardly uses any resources. “We” code locally on my office Mac and push to GitHub, then I screen share into the mini and have it download changes from GitHub. It’s a very nice system.
\nI will soon investigate Vercel as an option for a VPS.
\nLately, another good use for Claude/ChatGPT has been to upload my HTML and CSS files for cleanup, commenting, adding a nice Table of Contents, etc. It makes me feel better to have my personal blog web pages neat and organized.
\nWell, that’s it until the next web app or, hopefully, an iPhone app soon. I’ve taken many courses on iOS apps and Swift, and it never clicked for me; it’s a very hard language. I much more enjoy Python, HTML, CSS, and some JS. Excited to see how Claude and I work together on that.
\nIt’s been a wonderful day futzing with this.
\nI can’t have you check out the live web app because it’s not on the internet, just on my Tailscale Network, but here is a screenshot:
