I would like to share the first version of an app I built that helps you start your session on a medication in the pursuit of effect awareness and harm reduction
It tracks the onset, come up, peak and offset based on National Library of Medicine, FDA, and community resources like Tripsit Me and PsychonautWiki.
You can add a second dose to the same medication if needed and see how the effect timeline and intensity could look like.
This tool is for reference only, its not used to accurate chart your personal experience... but a reference to what is available on the internet about the compound.
The app is completely free, data is locally stored, and no cookie is being used here. Everything is GDPR compliant and privacy is the upmost priority for this app.
If you have any feedback I would love to hear. I want to continously improve this app and hopefully help people understand where they are in their journey and hopefully prevent harm for the community.

You can check it out at:

Cheers,

How does the app monitor chemical progression? Does the app recognize amount when taken and monitor the dosage as the substance becomes less over tine?
 
You mean the amount of chemical that is present in your blood stream? I actually have that feature, but its currently being polished. Beside the subjective effect, you will be able to track how the chemical is being eliminated from your body...
