Introducing TerpTracer: cannabis concentrate telemetry built for the people who actually use it
A new progressive web app lets cannabis consumers scan any COA, log their own sessions, and surface the terpene patterns that match how a strain actually makes them feel.
Every cannabis concentrate ships with a Certificate of Analysis. Every dispensary visit ends with a label, a QR code, and a printout. And then — almost universally — that data goes in the trash.
TerpTracer, a progressive web app launching today, is a small bet against that pattern.
Point a phone at any COA QR code. The app decodes it in under a second, pulls the terpene profile, cannabinoid breakdown, and source lab, and drops the whole record into a personal stash. From there, every session a user logs — temperature, dose, duration, mood — stacks against the chemistry. Patterns surface. The strains that focus a user start to look different from the ones that don’t. Not because the app told them, but because their own log did.
The product
- Universal COA scanner. Live QR decoding with an OCR fallback for printed labels. Currently parsing twelve major U.S. testing labs and growing.
- Stash and session log. Brand, strain, weight, price, terpene radar — all on one record. Every session inherits the chemistry of its source batch.
- Mood × terpene correlation. Six mood axes, six terpene axes, charted over time. Not a horoscope — a journal.
- TerpRadar visualization. Side-by-side, normalized terpene profiles for any two stash items. The pattern a user keeps coming back to becomes visible.
- AI companion. Ask TerpTracer plain-language questions about a personal dataset and get a contextual answer.
Why now
The cannabis industry produces an enormous volume of lab data — every batch, every state, every shelf. The consumers who actually use that product are the only stakeholders who have never had a place to put it. Dispensaries warehouse it. Labs report it. Brands market off it. The person at the end of the chain — the one whose body the chemistry actually meets — has been left with a printout and a guess.
TerpTracer is a tool for that person. The data belongs to them. The correlations belong to them. The export is theirs to download.
Free, paid, and what it costs
The free tier covers ten scans a month, unlimited session logging, mood tracking, the basic terpene radar, and PWA install on iOS and Android. Premium — $9.99 a month — lifts the scan limit, adds AI correlation insight, multi-stash comparison, CSV export, and Bluetooth device telemetry for users running a BLE-capable rig.
There is no dispensary tier. No data resale. No advertiser dashboard. TerpTracer is funded by the people who use it.
Where it runs
TerpTracer is built as a progressive web app: install from the browser, no app store gate, full offline support after first load. It runs on any device with a camera and a recent browser, and is live now at terptracer.com.
