Show HN: Open Wearables – self-hosted wearable data platform with an AI layerHi, I'm Bart, one of the maintainers of Open Wearables.For the past few months we've been building an open-source, self-hosted backend that normalises health and fitness data from multiple wearable providers (Garmin, Whoop, Apple Health, Samsung Health and others) into a single AI-ready REST API - and thought it was worth sharing here too :)We built this out of our own experience doing custom wearable integrations for clients, and from working with paid SaaS solutions that often lack the flexibility to customise data pipelines or debug what's actually happening under the hood. Surprisingly, there weren't any mature open-source projects filling this gap.What you get:- A single normalised API covering 60+ health metrics (cardiovascular, sleep, body composition, activity, respiratory) and 80+ workout types across all supported providers- A dashboard to manage users, API keys, and sync status — with a full view of each user's health data across connected devices- An AI layer via MCP, letti

Show HN: OxiLean – Pure Rust Interactive Theorem Prover (Zero C Deps, WASM)Hey HN,Just dropped v0.1.0 of OxiLean yesterday.It's a full Interactive Theorem Prover written 100% in Rust (1.2 million lines across 11 crates). Inspired by Lean 4, implements Calculus of Inductive Constructions, universe polymorphism, dependent types, full tactic framework (intro/apply/simp/ring/omega etc.), and even LCNF-based codegen.Key points that actually matter: - Kernel has literally zero external crates and zero unsafe. Memory-safe by design, no unwraps, explicit errors everywhere. - Runs in the browser via WASM (npm package @cooljapan/oxilean ready). - REPL works out of the box: cargo run --bin oxilean - No C/Fortran anywhere — unlike original Lean.Repo: https://github.com/cool-japan/oxileanWASM demo snippet in README if you want to play instantly.On my machine I've already proven 99.24% of MathLib4's 179,668 declarations (aiming for 100% in 0.1.1 soon). Been grinding this because I got tired of C++/OCaml build hell in formal methods tools.Curious what you think — especially

Show HN: LiveTok – AI Receptionist for Veterinary ClinicsHi HN! I'm Gustavo, building LiveTok (https://www.livetok.ai) – AI agents that handle phone calls and WhatsApp for veterinary clinics.Vet clinics lose clients to missed calls. The front desk is juggling check-ins, anxious pet parents in the waiting room, and a phone that won't stop ringing. After hours, it goes to voicemail – and most people just call the next clinic on Google instead of leaving a message.We built LiveTok to answer every call, 24/7. The AI receptionist books appointments, answers common questions about hours and services, and routes to a vet tech when the conversation needs human judgment. It handles the routine stuff so your staff can focus on the animals in front of them.Clinics using it are seeing up to 40% more appointments – mostly from calls that previously went unanswered or to voicemail.Setup takes about 5 minutes – connect your phone number, add your clinic's info and availability, and it's live. No coding required.The interesting technical challenge has been

LEDs/M vs. 60 LEDs/M: Solving Dotting and Voltage DropMany makers default to standard 60 LED/m strips, but they often result in visible hotspots ("dotting") unless used with thick diffusers that kill 30-40% of the light output. I've been digging into the specs for High-Density (120 LEDs/m) strips to see if they are worth the extra cost and complexity. Here is what I found: 1. The "Dotting" Physics With 60 LEDs/m, the gap between sources is ~16mm. In a channel with a depth of

Show HN: RISCY-V02: A 16-bit 2-cycle RISC-V-ish CPU in the 6502 footprintFinally finished my little CPU project, RISCY-V02. I built it (with Claude) to challenge the notion that the 6502 was a "local optimum" in its transistor budget. Given the constraints of 1970s home computers (~1 MHz DRAM, so raw clock speed doesn't help), could RISC have been a better design choice? This design argues yes: pipelining, barrel shifters, and more registers beat microcode PLAs, questionable addressing modes, and hardware BCD.Highlights:8x 16-bit general-purpose registers (vs 3x 8-bit on 6502)2-stage pipeline (Fetch/Execute) with speculative fetch61 fixed 16-bit instructions2-cycle interrupt entry (vs 7 on 6502)13,844 SRAM-adjusted transistors (vs 13,176 for 6502 on same process)1.0-2.6x faster than 6502 across common routinesGDS viewer: https://mysterymath.github.io/riscyv02-skyTiny Tapeout Shuttle Entry: https://app.tinytapeout.com/projects/3829

The Future of Healthcare Will Be Built on Enhanced DataTraditionally, healthcare relies on sporadic data collected during scheduled clinical visits. However, human physiology is an ongoing process, continuously responding to factors such as environment, activity, stress, pollution, allergens, and disease progression.We are advancing toward a transformative era characterized by continuous, real-world health monitoring enabled by sophisticated sensors, cloud computing infrastructure, and artificial intelligence. One of the most valuable yet underexploited physiological signals is exhaled breath.Exhaled breath contains a wealth of biochemical information, including markers of metabolism, inflammation, environmental exposures, physiological stress, and the early stages of various diseases. The primary challenge has not been the value of this signal, but rather the difficulty in capturing and analyzing it consistently, at scale, while maintaining anonymity.Innovative platforms such as Healthmetryx are addressing these challenges.

Show HN: A user daemon to provide an age-bracketing API(Before you react: I think these laws are pointless and dumb too, but they're still laws so here we are)Hi all, I saw a lot of talk about the new California (and pending Colorado) laws about requiring operating systems to provide an API to return a user's age bracket to applications. While I think most people agree that this is asinine, pointless, full of holes, open to abuse, etc. etc., it's also a legal requirement anyway.I've been playing with Claude Code lately and so I thought this would be a useful experiment - a small, self-contained project with a finite surface area and well-defined requirements. I should say the experiment wasn't whether Claude could do this, but whether I could provide decent instructions for Claude to do this and what level of detail I could get away with.Anyway, here's my latest project - aged, the age daemon. It's a straightforward app that I could have written myself despite being new to Rust, but the real experiment was in the extra features that I had

Show HN: Sous Clip – Extract recipes from short-form cooking videosGreetings HN!Its my first post here, and I'm delighted to announce a cool self hosted, privacy-focused app I've been working for a while - Sous Clip!The idea is simple: Share reels/shorts/TikToks to the app, it automatically extracts ingredients, cooking instructions and anything else using an AI provider of your choice (ChatGPT, Claude and Ollama for now, more coming soon!) and stores is locally for ease of access. It also comes with a PWA to easily share reels and access stored recipes through your mobile phone.From what research I've done, there are applications that already do this, but are paid services and require you to store everything on their servers. This app gives you the freedom to do what you want with this!Glad to hear feedback and feature requests!Direct GitHub link - https://github.com/SachinVenugopalan30/sous-clip

Show HN: Selva – Amazon for AI AgentsHey HN,I built Selva, a skill (CLI + API) that lets AI agents search for products, compare options, and buy things on your behalf.How it works:• Tell your agent what you need ("order more coffee pods" or "find some toothpaste") • It searches Amazon, finds options, and handles checkout • You save your card with us via Stripe, your card details never touch our servers and are never seen by your agent • You set a dollar threshold, anything above it pauses and asks for your approval via emailWhy I built this:I've been wanting to delegate some routine shopping tasks to my agent, but it kept getting stuck on captchas, auth screens, etc. Also didn't want it to have my credit card in its context, so I built this system where the card is stored securely with Stripe and the agent has to email me for purchases above X dollars (configurable).Details:• Works as an OpenClaw skill • Searches across Amazon and Shopify stores • Handles the messy parts of e-commerce and browser operations so your agent

How I stopped going to my agent and made it come to meI've been using openclaw for a while now and the thing that clicked for me was realizing how much of it is built for the agent to take initiative. I started by going to the agent whenever I needed something, but there's a whole other side where the agent comes to you, and once you set up a couple of these it's hard to go back.1. Heartbeat + HEARTBEAT.mdYour agent wakes up every 30 minutes, reads HEARTBEAT.md, and acts on whatever you've written in there. You can tell it to check your email for anything urgent, track a package, watch the weather, whatever makes sense for your day. Just plain english. The cool part is the agent can edit its own HEARTBEAT.md too, so if you say something like "keep an eye on X for me" in conversation, it'll add that to its checklist without you touching any files.2. Cron jobsHeartbeat is good for "check this periodically" but if you need something at an exact time, cron is the way to go. Morning briefing at 8am, weekly recap of your github notifications, a

BaZi – Deterministic life-charting from the Chinese calendarI've been fascinated by BaZi (八字), a Chinese calendrical system that maps birth date/time to Five Element interactions. Unlike Western astrology, it's essentially a deterministic lookup + combinatorial analysis — same inputs always produce the same chart. The core algorithm converts Gregorian dates to the Chinese Sexagenary cycle (天干地支), then derives Four Pillars (year/month/day/hour), each a pair of Heavenly Stem + Earthly Branch. From there it computes element balances, "Ten Gods" relationships, and luck period progressions. I built a web tool that runs this calculation and layers AI interpretation on top for plain-English explanations: https://xuanseal.com Some interesting technical challenges: - The Sexagenary cycle conversion requires handling the solar term calendar (节气), which doesn't align with Gregorian months. I ended up using astronomical algorithms rather than lookup tables for accuracy. - BaZi has ~30 named element interaction patterns ("Clash," "Combine," "Punishment," et

Show HN: Simvyn – Universal mobile devtool, no SDK requiredHey HNI've been building mobile apps for half a decade. There are so many moments where you need to quickly check something — how does this screen look on a 12-inch device? Does the layout break in German where translation strings are twice as long? Does the geo feature work when the user is in Tokyo?Then there's the everyday stuff — clearing app data to re-test onboarding, installing a fresh build on three devices at once, toggling dark mode to check contrast, sending a test push notification with a specific payload, grabbing screenshots for the App Store listing, checking what's actually in the local SQLite database when state looks wrong.Each of these is a few terminal commands, a trip to Xcode/Android Studio, or some menu buried three levels deep. Over the years I wrote a lot of bash scripts. Then bash aliases. Then more scripts to chain the aliases together.To consolidate all of that and make the DX actually pleasant, I built Simvyn — a local web dashboard + CLI that wraps simctl,

Fly.io deleted my apps and DBs in an unrelated organization without warningHi HN,I’m experiencing a destructive and seemingly erratic behavior from Fly.io's automated systems that resulted in a total loss of data across multiple organizations.I have been using Fly.io since July 2023 with two distinct organizations:Org A: Used for some Selenium-based automation experiments in late 2025 and other unrelated private projects through the years.Org B: A long-standing production environment with a Postgres database, active since 2023 with a consistent billing history.The Incident Recently, I discovered that everything across all my organizations has been nuked. Apps, databases, and even the volume snapshots (backups) have vanished. The dashboard for my database volume now simply says "deleted 16 days ago."The contradiction in their system is staggering:In both organizations, I see a semi-transparent banner: "Your account was flagged by our fraud protection system. Learn more" (the "Learn more" is not even a link).However, the "Billing" page for Org B still claims th

Show HN: Compile all your competitor research in one placeHey HN!We built SyncIntel, an internal tool we use at Comsync [https://comsync.in/] to power our other products, and we're excited to share what we've been building.We kept running into a problem while building Comsync. Our competitor research was scattered everywhere. We'd run deep research through Gemini, Claude, and other AI tools, read through lengthy documents, and then... lose track of everything. Important insights would disappear into browser tabs and forgotten Google Docs. We needed a dead-simple way to track competitors, their customers, and turn that intelligence into action. So we built SyncIntel, which was first used as an internal tool to power our other products, and now we're making it available to everyone.Competitor research shouldn't end at a PDF nobody reads again. SyncIntel takes it further. It discovers competitor customers, builds ideal customer profiles, finds matching prospects, and generates personalized outreach. All in one place, always up to date.Whether yo

Show HN: Groundctl – "Terraform plan" for your local developer machineHi HN,I built groundctl because every team I've been on has the same problem: "it works on my machine." Someone upgrades Node, someone has the wrong Terraform version, a new hire spends two days debugging a setup that differs from everyone else's.Existing tools don't solve this. chezmoi manages dotfiles, not tool versions. mise/asdf manage language runtimes per-project, not team-wide standards. Ansible is overkill for local machines.groundctl is a single Go binary that:1. Scans your machine and creates a `.ground.yaml` standard 2. Compares any machine against that standard (`ground check`) 3. Auto-fixes drift with one command (`ground fix`)It detects 18 tools (node, python, go, docker, terraform, etc.), works across macOS/Linux/Windows, integrates with 7 package managers, and runs in
