I'm a fitness trainer and I spent years watching clients track everything HRV, VO2Max, sleep and understand nothing. The data was there. The body literacy wasn't.
So I built Forjum.
It reads physiological data from your Wear OS smartwatch and maps it to 5 RPG stats:
Forjum exists to teach you to read your own body so accurately that one day you wake up and don t need it anymore. You know when you ve pushed too hard. You know when you re recovered. You know what your training is actually doing to you not because a screen told you, but because you ve learned to feel it and understand it.
We called it learn and graduate.
The five stats in Forjum Might, Agility, Constitution, Spirit, Presence are derived directly from Apple Watch sensor data. HRV, VO2 max, sleep architecture, heart rate, movement patterns. They grow with consistent training. They decay with inactivity.
A couple weeks ago, Boris Cherny (the creator of Claude Code) shared a bunch of really useful tips on getting the most out of Claude Code. #1 at the top of the list: do more in parallel. He himself runs 10-15 Claude codes in parallel.
His advice and practice makes sense: coding agents give us the ability scale infinitely. At this point, the only real limiter is our own ability to manage all of these agents.
I posted a random thread on X about the cost of living in the Netherlands. Nothing about what we're building. Just genuine thoughts about life in the Netherlands.
It hit 1M+ impressions. And here's the weird part we got a ton of signups and paid users for Starnus from it. Without ever mentioning the product.
Meanwhile, my "here's what Starnus does" posts? Way less engagement.
This genuinely messed with my head. I'm sharing the actual X post below
