Understandung
Your gut has been trying to tell you something.
What it does
Every gut health app logs food and leaves you to figure it out. None actually find your triggers. I have IBS, so I built the app I needed. Understandung is a gut health intelligence platform.. not a food diary. A 13-layer correlation engine maps ingredients to symptoms across your personal transit time. AI copilot answers "why did I feel terrible yesterday?" using your data. Bayesian confidence scores, not guesswork. Free tier forever. No ads, no data selling. Built by a patient, for patients.

- TYTrack your calories easily by saying what you ate2024 · calorio.xyz · ▲17
Hi guys, I created this app to solve one of my own problems: I found calorie tracking to be a real pain. Now, instead of scanning barcodes, scrolling through lists, or taking photos of food, I just speak into my phone (or computer), tell Calorio what I’ve eaten, and it handles the rest. It uses OpenAI’s APIs to process audio and map foods to calories. It’s free to use without an account, but if you want it to tally daily calories and remember everything you’ve eaten, you’ll need to sign up with your Google account and subscribe (you get 7 days for free). I would really appreciate any…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…
