https://curvefit.app it's a weight-training app that helps you train along your "pareto frontier" of weight vs reps. The idea is to train at lower weight-higher rep, medium weight medium reps, and higher weight, lower reps for every movement. I tried to develop my own weight training program following bits and pieces of advice from bodybuilding forums and ended up injuring several tendons in my first year. So I did a…

Ok, presuming this is going to be a monetized thing aiming to compete in the market. (if not what follows should be ignored). What about your app is better than what already exists from https://macrofactor.com/workouts/ , https://rpstrength.com/pages/hypertrophy-app , and maybe https://biolayne.com/workout-builder/ ? All 3 incorporate some form of RIR progression, varying rep ranges, program builders, and (at least i…

I don't intend to monetize, I only want to compete for data. I think it's an interesting field and I'd like to be able to contribute back to the science by using the data gathered. I think these workout apps try to be opinionated about what an effective program is, but they try harder to make money, so they generally bend over backwards to accommodate whatever program the paying customer wants to do. Mine is more opinionated. I think this is the best way to lift weights for a wide range of athletes who are interested in getting stronger and bigger with the least amount of wasted effort and lowest chance of injury, the simplest way to record it, and the best way to get a statistically defensible understanding of how your strength is changing over time. If you want to do something different, as you mention, the space is crowded with apps.

Hoo boy. It's an awesome idea, don't get me wrong - and it's work that should definitely be done. But I've worked professionally in this space and it is wildly complicated. I've never seen how things are done on the federal side, but US states have various modes of "electronic filing" for rules and codes - and there's a ton of complexity. It's the kind of thing that sounds insanely boring on the surface, but there's…

Thanks! Super interested in hearing more about some of the battle-scars you've acquired from working in the space if you're open to sharing? Very early in the journey here, so still have a ton to learn! So far, it seems like the federal space is relatively well-behaved compared to your experience with states. Most agencies standardized on the USLM schema[^1][^2] in 2013. Before that, it's a hodge-podge of XML and pla…

I am not sure how much I'm allowed to say publicly between NDAs and contracts and all that fun stuff (I may already be over the line, tbh) - but feel free to drop me an email at the address in my profile and I can point you to a few things that might be of interest.

Still working on my personal projects, for example an open source digital tool (code) library for humans and AI agents [1] (alpha) source code coming soon [2] and my own AI agent. But 95% of my time is spend on developing and researching new AI/ML algorithms, crazy 16 hour workdays but loving it!

Im working on a tool that catches silent failures in agents before you deploy them... And "NO" it is not like langsmith/langfuse etc. they tell 'which' agent failed, but my tool (Argus) tells 'why' that agent failed. https://github.com/ArgusLabs-ai/ARGUS Reviews/Feedback are much appreciated!
