Smart Bar
Feel the correction
Tracks its orientation in real time. A haptic pulse, the LED ring and sound cue the fix while you move.
Stingray XR · by MindBridgeXR · Doha
A balance coach that corrects you during the movement.
Smart Bar, Smart Mat and a camera app that cue your body back to balance mid-rep, and share every session with your coach or therapist.
The moment
“My home programme was a PDF of photos from the internet. Nobody could tell me if I was doing it right.”

1 session with a professional, judged by eye6 days alone, with no feedback at all
Correction has to happen inside the movement, not at the next appointment.
The product
Three inputs. One session record.
Use the camera on its own, or add the bar and the mat. Everything lands in one synced, replayable session your coach or therapist can review.
Smart Mat
See where your weight goes
Measures your left/right weight split and centre of pressure under your feet, and folds flat to travel.
Camera tier
Start with your phone
Record a movement test with a phone, tablet or laptop camera. No hardware needed to begin.
How it works
The loop closes on the device, not in the cloud.

Sense
Bar orientation, mat weight split and centre of pressure.
02
Decide
Your target and tolerance are checked on the device itself.
03

Haptic pulse, LED ring and sound, while the rep is still happening.

Design DNA
Ecological symmetry.
Stingray takes its cues from the animal it is named after: a creature that senses its surroundings, glides through resistance and stays level in moving water.
Electro-reception
In natureSenses its environment through invisible fields.
In StingraySensors in the bar and mat read the orientation and weight shifts you cannot see.
Shagreen texture
In natureMicro-scales that give grip and feel warm to the touch.
In StingrayA carbon-fibre bar with copper end caps, made to be held.
Fluid hydrodynamics
In natureWings that glide through resistance without aggression.
In StingraySoft, flowing forms, and a mat that folds flat to travel.
Kinetic silence
In naturePower delivered silently, just efficient motion.
In StingrayCues through touch, light and sound, with no screen needed.
Central nervous axis
In natureA stable spine keeps it level in turbulent currents.
In StingrayThe bar becomes a digital spirit level for your body.

The founder
Built from a problem he lived.
Akram Hidri is the founder and CEO of MindBridgeXR. He leads Stingray’s product design, design for manufacturing, and its mechanical and PCB design.
He started his career with his hands on machines, as an aircraft mechanic on the Airbus A320 family at Tunisair Technics, where precision is a requirement, not a preference.
He retrained as a designer, earned a Master’s in Space Design and delivered more than 50 interior and product projects before founding the immersive-tech studio Creatrea in 2019. With his team, he spent three years at Mada Center designing the Flight Journey Simulation Lab, the project that became AutismoLab, which he founded.
Stingray started with his own back pain: limited time with a therapist, a home programme printed as a PDF, and no way to know if he was doing it right.
“Even when you can’t reach your own dream yet, you can build someone else’s.”

Internship programme
Trained with us. Building with us.
Our internship programme brings students from UDST, Qatar University and HBKU into the build, across mechanical, electrical and software engineering, information systems, marketing and accounting.
Join the pilot.
We're looking for clinics, clubs and coaches in Qatar to test the first Stingray kits with us in 2027. Investors are welcome to get in touch too.
