We built a free iOS app with 22 compounds, 100+ peer-reviewed studies, and 46 research PDFs.
No ads. No paywalls. No agenda.
Just evidence-based drug education and harm reduction.
TestFlight beta opening soon.

Every one of those links to the paper it came from. You verify it, you don't trust me.
On the App Store as Brought To You By — an educational reference, not advice. If you or someone you know uses, know the risks first.
Most drug information online is useless in the way that gets people hurt: either "just say no," or a hype thread with zero sourcing.
Neither tells you the thing that actually keeps you alive. That's the gap Brought To You By was built for.
Fentanyl overdose is reversible if someone's there with naloxone (Walter, JAMA, 2023). Knowing the signs and carrying it is the single highest-leverage thing.
Psychedelic research is having a moment. But accessing it still sucks.
Studies are scattered across journals, behind paywalls, buried in databases.
BTYBD puts 236+ peer-reviewed studies in a searchable, filterable pocket reference:
This isn't meant to replace PubMed.
It's meant to make the most important findings accessible to non-academics.
If you're curious about the science but don't want to navigate journal databases, this is for you.
The technical details:
- SQLite database on-device (iOS + Android)
- No network calls required after install
- No crash reporting that captures user content
- Journal entries encrypted at the OS level
- Zero telemetry
The hardest part? Distinguishing "no known interaction" from "not studied."
Absence of evidence isn't evidence of absence.
The matrix flags unstudied combinations differently from known-safe ones. That distinction matters.
