Run Smarter.
Every Stride.
Biomechanical analysis after every run. Understand your form, reduce injury risk, and unlock your potential with data built around your unique stride.
"Aletheia helped me train smarter, understand my body better, and push past limits I once thought were permanent."
Next generation running intelligence.
The Philosophy
Most runners train based on pace and distance. But the forces governing your performance are invisible , until now. Aletheia captures the biomechanical data that defines your running form, and turns it into actionable insight after every single run.
Take Aletheia
for a run
Wherever you go; trail, road, treadmill, or track.
Aletheia tracks your motion
By tracking your motion, Aletheia can create a picture of how you move.

Comprehensive Metrics
Track What
Really Matters
10+ unique metrics, each one targeting a specific aspect of your running form.
Efficiency
Measures how effectively you convert energy into forward motion.
A high efficiency score means less energy is wasted on vertical bounce, lateral drift, and braking. More of every stride propels you forward.
What this means for your training
Improve your efficiency and you can run faster for longer at the same perceived effort.

Trusted by Runners
& Clinicians
"It's almost like having an assistant coach with me, helping me stay aware of how I'm moving, when I'm compensating for an injury, and when I need to slow down."
Cavin Parrilla
Runner
"What Aletheia has done for me is connect how I feel during a run with what's actually happening biomechanically. It's given me confidence in my running again."
Jeff Neal
Runner
"Right away, I could clearly see that my left side wasn't producing as much force as my right. It's helped me realize how much more I'm capable of than I originally believed."

Victory Performance & Physical Therapy
Physical Therapy Clinic · Los Angeles, CA
"When we integrated the run sensor into our Running Assessments, we immediately noticed how closely the data aligned with what our physical therapists were already observing. That validation matters. It reinforces our clinical findings and gives us something tangible to share with clients."
"Proof of concept isn't just a nice-to-have; it's a game changer for client buy-in and motivation."
Performx Physical Therapy
Outpatient PT Clinic · Salem, OR
"As an outpatient PT clinic, we use this app to guide our running assessments, and it's become a genuine asset to our practice. The insights are detailed enough to inform our clinical decisions without slowing us down."
"A great tool backed by a great team."
Bespoke Physical Therapy Wellness & Performance
Physical Therapy
"Often, our athletes' issues do not manifest in a controlled treadmill environment. This tool allows us to gather critical data on running form during road and trail runs, enabling us to better support patients with their specific concerns."
"I have been very impressed with Aletheia."
