Inactive Subscription - The base functionality of the app without an active subscription offers a limited capability. - Without an active subscription users can scan a scene for a body or bodies and/or hand or hands detecting key points limited to the capability of Apple’s Vision API, but will not be presented numerical data on the relative biomechanical geometry of the subjects. - If an active subscription lapses users can still access, edit and share all History data collected during the use of previous active subscriptions but cannot gather and tabulate any new data until the subscription is renewed. Active Subscription - With an active subscription users can scan a scene for a body or bodies and/or hand or hands detecting key points limited to the capability of Apple’s Vision API and collect the data associated with each joint and relative position of the key points on the body with regards to spatial or temporal coordinates. - With an active subscription users can start Sessions and send the session data to History. - With an active subscription users will gain access to new capabilities with Angles Alpha as they become available with new updates. This will include new joint combinations to assess, relative positions of joints and limbs/fingers, and other undisclosed options coming in the future.

A professional and indispensable toolset for modern day physical therapists. The app helps you: - Increase efficiency, - Simplify everyday tasks, - Perform a variety of assessments, - Impress and attract more patients, - Explain diagnosis to patients, - Build patients' confidence and trust. Easy to use and provides valuable information to both, practitioners and patients. The app includes: - Posture analysis - Functional Movement Screen (FMS) analysis - Simple and precise Range of Motion (ROM) measurement - Angles and ROM measurements on images - Motion analysis (angles, velocities, accelerations) - 10 meter walk test (or any other distance) - 6 minute walk test (or any other duration) POSTURE ANALYSIS Fast, easy and intuitive. Find imbalances and asymmetries. Analyze whole body posterior, anterior and lateral postures, or examine in greater detail specific points of interest - analyze head and neck in front and lateral views, analyze condition of patients with facial paralysis or look for trunk asymmetries indicating a scoliosis. RANGE OF MOTION State of the art goniometer for smart devices. Leave cumbersome goniometers in a drawer and use your device to measure ROMs. Unlike traditional goniometers and other apps, there is no need for perfect alignment - just place the device in a most convenient way you can, let a patient make a movement, read the results and compare them to reference values. MEASURE ANGLES ON IMAGES Take a picture of a patient or select an image from gallery, and measure ROM or any other angles directly on the image. Show the measurements to the patient to allow him to comprehend his condition better by inspecting visual evidence. FMS ANALYZER Some movement compensations can be missed even by an experienced therapist. Also, it is not always easy to explain to a patient the magnitude of spotted problems. Our FMS analyzer can provide you with objective measures of the correctness of the performed movement and any imbalances you might have spotted or even missed. Visualized results are appreciated by both, therapists and patients. 6 MINUTE WALK TEST Enter a walkway length, tap 'Start', place the device in a patient's front pocket and come back in 6 minutes (or any other duration you set) for results. The app will calculate the walked distance, inform the patient when the time is out and allow you to enter parameters, such as blood pressure, BORG index, etc. 10 METER WALK TEST Perform 10m walk test, or set the distance to any other arbitrary length. Perform multiple trials (if needed) of normal-comfortable speed and maximum speed walks. The app will calculate velocities for each trial as well as average of all trials and generate a report. MOTION ANALYSIS Use the device as a sensor to capture and analyze motions of interest - arm swings, trunk movements, weight lifting, squatting, ... The movement is charted in terms of angles, angular velocities and accelerations and linear velocities and accelerations. Use it in therapy, use it when working with sportsman, use it wherever you find it useful! Help us get even better! Your opinion is very important to us so, please, feel to tell us what you think, what you like and what you don't like and what features you would like to see in the app: support@trinuslab.com Fantastic app, but is it free? Huge resources were needed (and still are) to develop and support such an app so, unfortunately, we cannot give it for free. However, even for the smallest of therapist's practices the cost is negligible and benefits are countless. Your small support will enable us to continually improve the app!
