Substance timing tracker
What did you take, and when should it wear off?
A small, blunt harm-reduction tool. Log an entry, see the active window, watch the countdown, and check overlap risk. Afterward, mark how it went so Peakeroo can warn you if you repeat a bad pattern.
Not medical advice.
These are rough educational estimates. Bodies differ. If you are worried, call a clinician, pharmacist, poison control, or emergency services.

Body factors
Yes, size can matter. It is still not enough.
Weight can change dose-per-kg exposure. Body composition, organ function, genetics, age, sex, route, food, tolerance, sleep, hydration, and other medications can also change onset, peak, and duration.
So Peakeroo should not pretend to calculate a perfect personal truth. The better product move is to show a wider uncertainty window and flag “higher relative exposure” when the amount and weight make that obvious.
Database direction
It needs to feel like a real library, not a toy list.
The demo now includes common OTC meds, caffeine, sleep aids, prescription stimulants, benzodiazepines, opioids, supplements, alcohol, cannabis, psychedelics, and other harm-reduction entries. Logs and feedback are structured so a future AI layer can spot personal repeat-risk patterns, but production medical content still needs review.
Watch the timer
Each card shows phase, wear-off time, and a live countdown.
Remember bad outcomes
If you marked a previous entry as bad, repeating it triggers a personal warning.
Critical disclaimer
Peakeroo is not medical advice.
Peakeroo provides educational information only. Substance metabolism varies by person, health status, food, hydration, medications, tolerance, genetics, and many other factors. Always consult a healthcare provider, pharmacist, poison control, or emergency service when unsure.
If someone may be overdosing, unconscious, having seizures, having chest pain, overheating, breathing abnormally, or acting dangerously confused, call emergency services immediately and tell responders what was taken, when, and how much if known.
