FAQ
Questions? We've got answers.
Devices ship as fast as we can hand-build them. Each unit is assembled and tested one at a time β no factory shortcuts β so we won't sacrifice quality to hit a date. You'll get email updates as your device moves through production, and we'll always be upfront about timing.
Founder's Edition units are $54.99. Your $5 deposit gets credited toward your final balance ($49.99 at shipping). Founder's Edition is the very first wave of Fartometers β later production runs may be priced differently, but Founders always pay the launch price.
No problem. Deposits are 100% refundable any time before your device ships β just email support@thefartometer.com and we'll refund you, no questions asked. After your device arrives, you've got a 30-day window to return it for a full refund. Full details on our refund policy page.
Every Fartometer comes with a 60-day warranty covering manufacturing defects. If your device stops working through no fault of your own (not from drops, water, or modifications), email support@thefartometer.com and we'll repair or replace it. We hand-build every unit and stand behind them. See full warranty details.
100% real. It uses genuine electronic components β an SGP30 gas sensor, an ESP32-C3 microcontroller, a rechargeable LiPo battery, an OLED display, and a speaker for sound effects. Every device is hand-built and tested by Mason in upstate NY. The Fartometer is intended for entertainment purposes only β it's not a medical or air quality device.
The SGP30 sensor reliably picks up the gases that create odors, so it's genuinely good at detecting stinks. That said, it measures all VOCs in the air β so strong cooking smells, cleaning products, or cologne can also score. The 1-1000 scale is designed to be fun, not laboratory-precise. It's entertainment, not science.
The device itself works completely standalone with anyone. The companion app is currently a web app that works best on Android Chrome and desktop Chrome via Bluetooth. A native iOS app is in development for when Founder's Edition units ship β Founders will get early access.
The 100mAh LiPo battery gives you several hours of active use. Since the device spends most of its time idle waiting for you to press the button, real-world battery life is excellent β likely a full day or more of casual use. Charges via USB-C in under an hour.
Nope. The device works fully offline β it scans, scores, plays sounds, and saves your history locally on its own. Pair with the app via Bluetooth whenever you want to sync scores to the leaderboard. No WiFi setup required, ever.
Absolutely. The device works completely standalone β just press the button and get your score. The app is optional but adds leaderboards, score history, friend challenges, and the social feed. It's way more fun with friends but not required.
