Ask HN: What Are You Working On? (March 2026)

I'm still trucking away on Digital Carrot (https://www.digitalcarrot.app/)

It's a cross platform productivity app that lets you block apps, websites and games until you reach a set of verifiable goals such as walking 10,000 steps, physically going to the gym or finishing all your tasks on your to-do list.

I just finished the Android version a few weeks ago!

I've started building better, simpler tools for military use. Every soldier who's touched a DAGR (AN/PSN-13) knows the pain — $2,500, weighs a pound, UI from 2003, and half the time you're fighting the device instead of navigating. I built Red Grid MGRS to put the same core land nav capabilities into a phone app.

What it does:

Live 10-digit MGRS grid Dead reckoning, two-point resection, pace count, back azimuth Magnetic declination (auto or manual) Waypoint lists with bearing/distance and a wayfinder arrow 6 radio report templates (SALUTE, 9-Line MEDEVAC, SPOT, CASEVAC, ICS 201, CFF) NATO phonetic voice readout NVG-compatible green theme Fully offline — zero tracking, zero network calls, zero data collection. On the App Store. Open source on GitHub.

What surprised me is how little effort this actually took to build. The MGRS math, geodetic calculations, report formats — it's all public domain stuff that's been around for decades. The military is full of overpriced, outdated systems doing things a modern phone handles better. I'm hoping this sparks some genuine innovation, because the people who depend on these tools deserve better than what they're getting.

Working on version tracking for AI agent skills. When skill files move between Claude, Codex, Copilot, and local storage, they lose their version identity. Skill-Provenance embeds version headers, a changelog, and a manifest inside the skill bundle so any session can verify what it received. https://github.com/snapsynapse/skill-provenance It came out of building a larger AI adoption measurement framework where I kept losing track of which version of which skill was running where. Turned out to be a gap nobody had addressed, even with six competing agent skill package managers launching in the same month.

You missed a perfectly good opportunity to explain your product :)

build tng.sh. nobody wants it. will kill it :)

was a fun project to do some rust
