Today, we’re thrilled to introduce a breakthrough that reshapes how people discover the world: the FOTRIC TD2 Geek, the world’s first smartphone acoustic imager that lets you see sound in real time — without draining your phone’s battery.
What once belonged only in lab environments and industrial engineering is now small enough to slip into your pocket.
The TD2 Geek marks a major leap forward for creators, explorers, educators, and innovators everywhere.
A New Sense for the Smartphone Generation
Human hearing has relied on just two ears since the beginning of time. The TD2 Geek takes that principle and amplifies it — literally — with a 64-MEMS microphone array.
Instead of just listening to sound, you can now see where it comes from. Instead of guessing what’s buzzing, leaking, chirping, or humming — you can visualize it instantly on your screen.
Covering 2 kHz to 50 kHz, TD2 Geek reveals both audible and ultrasonic sound sources. From a bird hidden in the trees to a tiny air leak in a workshop, TD2 Geek turns the invisible into bright, colorful acoustic maps right on your smartphone.
This isn’t just a new tool. It’s a new dimension of human perception.
Power That Frees Your Phone
Most smartphone accessories drain your device's battery. TD2 Geek does the opposite.
Built-In Independent Battery Enables Up to 4 Hours of Continuous Operation Without Draining Smartphone Power
With a built-in rechargeable battery, it runs for up to 4 hours without draining your phone’s energy. No drain. No overheating. No interruptions.
This self-powered design is the first of its kind in mobile acoustic imaging — and the difference is immediately noticeable. You can explore longer, record more, and stay focused on what you’re discovering.
Built for Real-World Exploration
Small, durable, and IP54-rated, the TD2 Geek is ready for adventure:
-
Nature Exploration: Track birds, insects, or ultrasonic wildlife
-
Urban & Industrial Diagnostics: Spot wall noises, electrical hums, or compressed-air leaks
-
Music & Voice: Visualize sound waves, resonance, and movement
-
STEM & Research: Help students and creators understand the physics of sound
It connects instantly through the FOTRIC Genie App on Android. Plug it in. Start seeing sound. No training needed.
