We push updates for our app pretty frequently and they've been passing review in an average time of 1 hour (around 7 updates in the last 60 days). Hope it stays that way.

missing '2022' in the title
Sadly the app doesn't work. There is no popup asking for microphone permission.

EDIT: I see there is an open issue for that on github

Re:VR Is Not Dead on Sunday March 29, 2026 @02:38PM (#47565857)
These are valid points but the upside of vr is still much bigger than the current downsides. The ability to explore worlds as if you're actually there is something no other medium really offers.

if you're experimenting with hrv/biofeedback then you might find Aidlab 2 interesting, it gives RR + GSR in one wearable (fyi I am the author)
Re:An Update on Heroku on Friday February 06, 2026 @10:46AM (#46914249)
yes,, render feels like the most natural next step right now (similar mental model). Still kind of nostalgic about Heroku, had really good times with it.

Same here! Still on a streak since day one

hey guys, we’ve had a chance to chat a few times. Fingers crossed for your launch here. Have you thought about Show HN? Your product is clearly needed, and I’ll always support standardization /open standards.

by tracking sleep, what exactly do you mean by that? sleep phases, sleep score, sleep duration?

the open-source models will catch up, 100%

No, and no nudity, no reference images. Example: 'athlete wearing a health tracker under a fitted training top'

Cool, but it's still unusable for me. Somehow all my prompts are violating the rules, huh?

Ask HN: Any Hardware Startups Here?

AI is eating the world. Feels like every hour there's a new SaaS or GPT wrapper launching. That's cool, but I'm curious who's still building hardware? I'm keen to meet those in our community taking on the often-quoted "hardware is hard" challenge.Would love to hear what you're working on, even if it's just a prototype: anything that involves devices, sensors, rockets, robots, cameras, wind...

Congrats guys on your release. I tried new VitalLens side by side with my medical grade tracker (Aidmed One) but the respiration numbers were quite off.

Curious if you've done any comparisons against actual hardware (chest-based or contact PPG), or if validation is mostly dataset based for now.

> It's not sexy, and as a result an overwhelming majority of the population is unaware about how to avoid succumbing to it

When I started building an ECG Holter in my early 20s, I tried to get some friends to use it and kept hearing "yeah, but it’s not exactly sexy to wear that thing." That’s when it hit me how little people care about prevention until something goes wrong. We still have a huge awareness gap to close.

Re:The trust collapse: Infinite AI content is awful on Thursday November 06, 2025 @10:10AM (#45836119)
So I went on X after a long break from social media, and my feed is full of tips like this one:

Growing on X is so simple I’m shocked it works.

100x comments a day

10x posts a day

15x DM’s a day

1x thread a day

1x email a day

This is how you grow your presence on X.

Even if having a presence matters, how can you actually say something meaningful if you post 10 times a day - there's no way (unless you just repeat yourself). Hopefully my algorithm's just gone weird but sadly the people I used to follow stopped posting.

Re:Show HN: Aidlab – Health Data for Devs on Wednesday October 15, 2025 @11:40AM (#45594270)
Hey, can you join our Discord: https://discord.gg/sPay3Xm? Reach out to me personally (@guzik1) - happy to help you with that as we've already had a few people who integrated with rpi, so I can share some tips and examples.
Re:Show HN: Aidlab – Health Data for Devs on Monday October 13, 2025 @12:37PM (#45570384)
Thank you! We've integrated a different chip for measuring chest movements
Re:Show HN: Aidlab – Health Data for Devs on Monday October 13, 2025 @09:39AM (#45568215)
sadly, comfort for chest straps compared to hand straps is a known issue and ours is definitely no different. Wve done a bunch of tests, tried different materials/custom solutions, and honestly we're still clueless how to make it significantly better (if anyone here works in textiles or wearable fabrics, I'd love to connect). So yeah, if wearing your Garmin for more than an hour already feels uncomfortable, ours probably won't be much better in that regard
Re:Show HN: Aidlab – Health Data for Devs on Monday October 13, 2025 @05:32AM (#45566492)
for regular users, since the device itself doesn't have any interface, we need to send at least some data so they can see it somewhere. the natural place is the phone, but not all of our professional clients liked viewing long ECG recordings or detailed metrics on a small screen, so we built cloud access mostly for convenience .

(to be clear - if a developer wants, they don't need to send anything to us)

Re:Show HN: Aidlab – Health Data for Devs on Monday October 13, 2025 @05:04AM (#45566325)
Thanks! Yep, the interface for a shell is available here: aidlab.com/developer/debug we are using Jquery Terminal + Web Bluetooth (sadly, I think it's not under active development anymore)

and yeah, when we started years ago, it felt natural that the next step would be to measure glucose from blood but the truth is with the current state of science, it's still not possible to do that 100% non-invasively.

Re:Show HN: Aidlab – Health Data for Devs on Monday October 13, 2025 @05:00AM (#45566297)
we don't have any plans right now to build a blood glucose sensor (although we already support a few external sensors - but not glucose monitors yet)

Show HN: Aidlab – Health Data for Devs

Hey HN! I'm Jakub, and together with my co-founders Agnieszka and Nathan, we built Aidlab, a wearable that gives developers gold-standard physiological data. Unlike health trackers with locked-down APIs, Aidlab ships with a free SDK [1] across 6+ platforms so you can just pip install aidlabsdk or flutter pub add aidlab_sdk or whatever platform (even Unity), and start streaming raw health data...

Re:A love letter to the CSV format (2024) on Wednesday September 10, 2025 @06:40AM (#45195789)
I am glad that we decided to pick CSV as our default format for health data (even for heavy stuff like raw ECG). Yeah, files were bigger, but clients loved that they could just download them, open in Excel, make a quick chart. Meanwhile other software was insisting on EDF (lighter, sure) but not everything could handle it.
Re:Protobuffers Are Wrong on Friday September 05, 2025 @01:03PM (#45140855)
We thought for a long time about using protobufs in our product [1] and in the end we went with JSON-RPC 2.0 over BLE, base64 for bigger chunks. Yeah, you still need to pass sample format and decode manually. The overhead is fine tho, debugging is way easier (also pulling in all of protobuf just wasn't fun).
