Informed by your body,
powered by AI.
Take control of your fitness journey.
Wearable EMG sensors read every muscle as you move. Place multiple sensors on any part of the body. Actus turns raw signal into real-time guidance on form, fatigue, and recovery, rep by rep.
Background video is AI-generated
Science meets intelligence,
on every rep.
Most training is still based on guesswork. Actus gives you clinical-grade muscle data and the AI to act on it.
Realtime Informed Feedback
Know exactly which muscles are activating, how hard, and whether your form is degrading, all while you move. Actus delivers per-muscle feedback on activation and fatigue in under 20 ms, so every rep is informed, not assumed.
Recovery Tracking & Injury Prevention
Measure how your muscles recover between sessions. Actus detects compensation patterns and muscle imbalances before they escalate into injury, essential for athletes returning from rehab and those pushing performance limits.
Optimizing Personalized Workout Programs
Every session generates objective data that the Actus AI uses to adapt your training. Progressive overload grounded in what your muscles actually tolerated, not generic progression tables. Train smarter, build faster.
Two products.
One platform.
The sensor captures what your body is doing.
The app tells you what it means and what to do next.
Actus Sensor
A precision EMG and 6-axis IMU sensor you place on any muscle. Up to 8 sensors per session, streaming raw signal to your phone at 1,000 times per second.
Actus Hub
Charges all your sensors simultaneously and keeps them firmware-ready. Snap in after every session — no cables, no fuss.
Actus App
Available for iOS and Android. The app receives raw signal from your sensors and translates it in real time, showing a live muscle map, catching fatigue before it hurts, and building your recovery score.
Training on feel
vs. training on signal.
Most athletes train blind. Actus changes what information you have access to, and what decisions you can make because of it.
From muscle to insight
in three steps.
Place the sensors
Featherweight EMG sensors attach to target muscles in seconds. Place up to 6 sensors anywhere on the body: quads, hamstrings, shoulders, arms, for complete muscle coverage.
Connect to your phone
Sensors stream EMG and 6-axis IMU data wirelessly to the Actus app at 1 kHz with sub-100ms latency. No wires, no complicated setup. Just open the app and train.
Read your signal
The Actus app and AI translate raw data into calm, glanceable guidance: what muscles to push, what to protect, and how to recover, rep by rep, session by session.
Back the future of
human performance.
We're building the technology that will change how athletes and coaches understand the human body. Actus is raising its seed round to bring real-time muscle intelligence from the lab to everyday training.
