Lethal Dose is an offline Android app built for candidates preparing for the American Board of Toxicology certification — flash cards, quiz banks, adaptive review, and a full mock board exam, all on your device.
Coverage across core toxicology, organ systems, ICH/OECD guidances, and the ABT top-300 pharmacology list — with the engine paying closest attention to what you keep missing.
Flip-animated cards with text-to-speech on either side, and a starred-cards shelf pulled from every category.
Multiple-choice quizzes per category with immediate color-coded feedback, so mistakes register while the reasoning is still fresh.
Pulls your weakest questions across every category — accuracy under 70% — worst first, with a direct link back to the study section that fixes it.
Coverage, accuracy, and mastery combine into one number, backed by a category chart and quiz trend line.
25, 50, or 100-question mock exams, weighted 70% toward your weak spots, with a category-by-category breakdown after.
Tap any section to have it — and everything after it — read aloud, so you can study away from the screen.
Open the app and every category is already there — no sync, no login screen, no waiting on a connection during an exam-week study session.
Lethal Dose was built offline-first on purpose — there's no account to create and no server to trust.
Nothing to sign up for. Install the app and your local library is ready — no email, no password, no verification step.
Quiz history, notes, and progress are stored locally in an on-device database. Nothing is transmitted anywhere.
Every category, question, and flash card ships inside the app. Study on a plane, in a basement lab, wherever.
Lethal Dose is built directly against the American Board of Toxicology (DABT) certification blueprint — that's the app's primary use case. The core toxicology and regulatory content also overlaps meaningfully with a few adjacent certifications, and can serve as helpful supplementary review for graduate coursework in toxicology-adjacent degree programs, though the app isn't tailored to any specific exam format or curriculum.
Applied toxicology practice draws on the same mechanism-of-toxicity, risk assessment, and biotransformation fundamentals covered across Lethal Dose's core categories.
Shares the same general toxicology foundation, though ERT's regulatory framework differs from the ICH/FDA-oriented guidance content in the app.
The app's ICH and OECD guidance categories (M3, M4, Q3 series, OECD 408/413) touch directly on regulatory toxicology topics relevant to RAC, though RAC spans far more than toxicology alone.
Also a useful supplementary study aid for graduate coursework in toxicology-heavy degree programs — MS/MSc in Toxicology, MPH with environmental or occupational health focus, PharmD, and DVM/veterinary toxicology tracks — where the same core mechanisms and regulatory frameworks are covered.
Not a substitute for board-specific prep materials or degree-program curricula — offered as helpful overlap, not an endorsement or affiliation.
Lethal Dose is built for board candidates — not a general reference, a study system with a score attached to it.
