Different problems.
Same philosophy.
Every tool we build starts with peer-reviewed research on how the body works, strips away everything irrelevant, and delivers something you can act on immediately, in plain language on the device in your pocket.
Circadian science
LayOvr models your internal clock using the two-process sleep framework and Phase Response Curves, the same science chronobiology researchers use, turned into a clear day-by-day travel plan.
Biomechanical fitting
Bike Fit applies validated fitting methodologies that bike fitters use in studios: LeMond saddle height and body proportion geometry, but instantly, in your browser, from your measurements alone.
Private by default
No backend. No analytics. No accounts. Your health data and body measurements stay on your device. That's not a cost decision. It's a principle every tool is built around from the start.
