InCaseOf
A Reddit thread turned into a free emergency app
What it does
I built InCaseOf after realising my mum, my emergency contact for every trip, would have no idea what to do if I actually needed her to act. No insurance details. No passport number. Nothing. InCaseOf lets you fill in everything once: medical info, insurance, key contacts, documents, final wishes. - Saves to your own Google Drive, encrypted. - You share a link and an access code with your contact. That's it. Free. No servers. 100% Private. Your data never touches mine. Give it a shot.

Hi, Creator here. I'm sort of reposting the same thing from about 208 days ago. The first version kinda sucked. I guess this is my first lean not-really-a startup experience. The new version is much better. http://thehorcrux.com/why-i-built-horcrux-app/ Let me know what you think, Here are some promo codes: 97HNR6HW4EPH K9R7KTWPTJJ6 WPM3MK4WXNHY 3P7N9RNPF4M4 3N49NP9P7TR6 Cheers, Suhas Sharma

Hey HN, I'm a longtime reader and this is my first Show HN (exciting!) It's a collaboration between me and two friends, and we're building this upon another app we made called EmailYak, an API to receive email. We're trying something new and releasing the documentation to an app while we're still building it. We'd love feedback. Do you belong to any of these categories? 1) You've built an app with two distinct groups of users (say, people with cars and those looking for a ride) and they were able to communicate with each other. Did you expose personal email addresses? Did you send…

I'm a solo dev. A few years ago, I got addicted to Reddit. Spent months in that loop. Being a programmer, I thought I'd be clever. Redirected Reddit's domain to nowhere in my DNS file. Worked great until I'd just... open the file and undo it 20 minutes later. So I made it irreversible. Locked the DNS file so it can't be edited unless I boot my Mac in safe mode. And if I do that, there's a script that instantly locks it again. Haven't used Reddit since last year. Problem solved, right? Wrong. I just replaced Reddit with Twitch and YouTube. Started keeping streams running in the background…
- IMI made a crossword app for language learnersApr 2026 · cranki.app · ▲8
Hi HN! In the last couple of weeks I've been working on Cranki: Cranki = Crosswords + Anki. (It's a stupid name tbh, haha) I like doing crosswords in Spanish (to learn vocab) but none of the apps out there allowed me to use my own list of words that I come across. So I built one instead. It's entirely client-side. No server, no database, no accounts, etc. Your words and stats are stored in local storage. I built this for myself but let me know if you like it!

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
