Precision instrument for your ritual.
DabBuddy reads your nail at 10 Hz, predicts the exact second it will reach your target temperature, and logs every session in a library that never leaves your device.
Six things
it actually does.
Heat curve prediction
Exponential-decay fitting on a rolling 5-second window, blended with 20 historical sessions. Knows when you're ready before you do.
Session library
Every session captured with peak, average, temp curve, predicted vs actual time. Searchable, filterable, exportable.
Material profiles
Quartz, titanium, ceramic, ruby — each with its own emissivity and learned decay constant. Switch without recalibrating.
Strain intelligence
Rating-weighted optimal temperature per strain. After 3+ rated sessions, it tells you the single temp that scores highest.
Global leaderboard
Three categories, four periods, privacy-preserving. Only aggregate scores leave your device.
On-device everything
SQLite on your phone. No cloud sync, no account, no tracking. Export JSON anytime. Delete whenever.
Three moves.
No waiting for someone else's servers.
Build or buy the device
LILYGO T-Display + MLX90614 sensor + LiPo, in a 3D-printed case. Full build guide open to customers.
Install the app
iOS, Android, or web PWA. Pair via Bluetooth once, the app remembers.
Heat, aim, wait
Point at the nail. The app shows a prediction countdown. When it hits zero, you're at target.
Built for the bench,
portable for the couch.
Your data never
leaves your phone.
Every session, temperature reading, strain note lives in SQLite on your device. No cloud sync. No account. No email required.
The only thing we see is an anonymous leaderboard score — a number, a username, nothing else. Not the sessions. Not the temperatures. Not the strains.
