The problem

Cortisol tracking today
costs $200 and a spit test

Hardware required

Saliva kits and wearables

Every cortisol tracker on the market needs you to buy physical hardware. Spit in a tube, wear a sensor, wait for results.

Reactive

Tells you after the fact

Current tools measure what already happened. By the time you see a stress spike, the damage is done. You crashed at 3pm and there's nothing you can do about it.

CortiCast

No hardware. Predictive.

We use established cortisol science and your daily habits to forecast your energy curve before your day starts. Free. Software only.

Your body already knows
how today will feel

Cortisol follows a rhythm. It peaks when you wake, dips when you fade, and crashes when you least expect it. CortiCast reads that rhythm so you can work with your biology instead of against it.
