Thanks for taking initiative; it's important, brave and admirable. I know kratom is used mostly in Thailand, where it grows naturally, but it has some adoption in US too and is imported regularly from a big community. Not sure where else is used.

I feel that an app is needed, not only for tracking purposes but also for education. So make sure you put it out there, share it around and collect feedback.

I guess since nobody's posting, I'll go again. I'm building a tracker for people who take kratom that will eventually take into account metabolism, adsorbtion modifiers, differences in strains and processing methods, etc... to work out appropriate taper timelines for quitting.
