Some ideas or wishes

[arisalthaus]

I really enjoy the status quo of HealthLog right now, although I secretly imagine an even larger healthcare system. Which would include (someday in the future)

• Tracker for gym / running (or in general sports/workouts) with like fields for active/total calories, distance traveled or like what excerise i did, how much weight i lifted or how many sets i did, etc.)
• food and nutritions tracker (would be nice to gather the information from Apple Health or apps like YAZIO if possible). Also very helpful to see how my nutrition (or things like sugar, salt, protein, etc.) impacts things like mood, sleep, recovery, etc.
  - light mode (yes fr)
• ability to import and track things like vaccines
• maybe some inspiration on what the Athlytic app does (even tho a lot of it is already implemented gladly)
• ill have a few more ideas in the future

And a few "Bugs" or rather things where I would have liked better "advice" or notice:

• I didn't know uploading files is only possible when accessing through https://
• The Apple Health import was buggy with that "file or directory cannot be found" (unsure if its alr fixed, saw an issue abt that)
• I changed a few target values (e.g. my weight to 100–110kg) but the target range color coding on the dashboard still shows a red area for weight between 100-110 kg). Same with resting heart rate.
• Coach or AI isnt properly working sometimes (even tho I've connected a chatgpt API token and chose it as the primarly provider)
• my sleep data was not imported. I don't know if it's because of the Apple Health export or if something went wrong with the import.
• the import example csv didnt work // the documentary for that only says "404 – Site does not exist"
• the page for each laboratory value does not really (or only sometimes) give me a limited view on if my value is in the healthy range or not. (Sometimes visible through the chart, sometimes not there; in general a more detailed page for those values would be nice)
• for example i have a OSA (sleep apnea) so i added it as a active "illness" (which is constantly) in my illness-area. But now the dashboard says im in some kind of resting mode since i have an active illness (even though my sleep apnea is getting therapied by an cpap-device for example)

In general i really like HealthLog and it already contains most of the things I wished for my "all-in-one" health-system. I dont want to criticize and especially i dont want to open up any real expactions towards you. Im glad its an free to use open source project.

There is a light mode

Oh true. Thanks. I didnt see that

@arisalthaus, sorry for the silence here. I thought I had answered and only saw today that I never did. That is on me, and I am glad I found it, because a lot has moved since July and several of your points turned into things that shipped. We clearly had similar thoughts.

First the honest part about direction, because it explains two of your wishes. HealthLog is not going to become a gym or body-optimisation app. There are apps that do strength logging and calorie coaching far better than I ever could, and I would rather not build a worse copy. What I care about is the other thing: everything health-related you produce gets thrown in, from the scale, the watch, the lab PDF, the Apple Health export, and comes back out structured, in one place, with the Coach able to read all of it. Less a daily driver, more fire and forget. So a strength log with sets and weights is not coming.

Nutrition is different, and closer than you might think. If you log food in YAZIO or anything else that writes to Apple Health, you can switch nutrition sync on in the iOS app, and the daily nutrients, micronutrients included, land in HealthLog where the Coach and the correlation engine can see them. So the question you asked, whether sugar or protein moves your sleep or mood, is exactly what that path exists for. What I will not build is the nutrition-versus-weight analysis itself. A friend of mine, @tarantila, built CaloGraph for precisely that (https://github.com/tarantila/CaloGraph), a self-hosted nutrition dashboard for Apple Health and YAZIO data, and it does that job better than anything I could bolt on here. The two sit well next to each other.

Now your list. Workouts are in, with distance, calories, heart rate, elevation and routes, from Apple Health and Strava. Vaccinations have their own record. Since v1.34 your own target range paints the band on the weight chart instead of the WHO band. A condition you live with no longer puts the dashboard into recovery mode; the record tells an acute illness from a chronic one. The Apple Health import error you hit is fixed, sleep history has a repair job, lab values show where they sit against their reference range on their own page, and the AI provider card now tells you what a failing provider actually answered, which is what was missing when the Coach quietly did nothing. Strain and recovery scores exist too, and the wearable side keeps growing. That part is not going away.

Two things you raised are still open, and you were right about both: the CSV example page in the docs is still a 404, even though the file itself is downloadable from the import panel, and nothing tells you that uploads want HTTPS before you find out the hard way. Both are on my list.

Light mode: @k-nacion beat me to it. It was there all along, top right.

Thank you for writing all of this down. I never thought people would use HealthLog this way, and a list like yours, from someone who clearly does, is the best feedback I get.

One correction to my earlier reply, because I got the HTTPS point wrong in a way that matters.

I said nothing tells you that uploads want HTTPS. The truth turned out to be worse and simpler: on a plain-HTTP origin, uploads did not need HTTPS, they were broken. The browser only allows crypto.randomUUID() on a secure context, and the app used it to label every upload and, since v1.37.18, to mint the idempotency key on every write. On a LAN self-host over plain HTTP that call threw before any request left the page, so nothing was saved and nothing said why. Not just uploads, every write, silently.

That is fixed on main now, with a random id that is not gated to secure contexts, and a guard so it cannot creep back. It ships with the next release, and the self-hosting docs now say what plain HTTP actually withholds: passkey sign-in, push notifications and installing the app to the home screen. Everything else, uploads included, works.

Thank you for reporting the symptom precisely enough that it could still be traced two months later.
