Tools
A dose calculator, a medication checker, and a tolerance calculator.
Medication interaction checker
SSRIs, SNRIs, lithium, MAOIs, antipsychotics, the ones that actually matter. Separates 'this will blunt the experience' from 'this causes seizures'.
Start here if you take anything at all.
Dose calculator
Scales the standard dried-cubensis tables by measured species potency, and shows the psilocybin figure alongside the gram figure.
Body-weight scaling is off by default, and argued against.
Tolerance calculator
How much sensitivity you have back, and how long until it is worth bothering. Built to explain why redosing fails rather than to help you chase it.
Answers 'wait how long', not 'take how much more'.
Calm mode
A countdown from when you dosed, what is normal for the phase you are in, a breathing pacer, and the red flags that actually warrant a phone call.
Works offline once you have loaded it.
