Hacaro vs GaitAnalysisPLUS
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Hacaro
This app measures physical fitness and exercise ability using smartphone sensors. It specifically assesses the Timed Up and Go Test (TUG) to quantitatively evaluate functional mobility. The app records and analyzes movement data to generate a universal score for gait assessment.
- Timed Up and Go Test (TUG) measurement
- iTUG Score calculation
- Division and acceleration graphs
- 3D acceleration graph volume
- Cloud data saving and retrieval
- Latest record display on home screen

Application that measurement of physical fitness, exercise ability became easy by familiar using smartphone "Hacaro (Hacaro)" series! From the "Hacaro" series, an application to measure "Timed Up and Go Test (TUG)" was born. iTUG i means Instrumented, that is, measurement with an instrument. The “Timed Up and Go Test (TUG)” is a widely used test as a quantitative assessment of functional mobility in medical and nursing care settings. The subject holds the iPhone in the abdomen, stands in a chair, stands up with the voice of the start from the iPhone, turns the cone 3 m ahead, rotates 180 ° back in front of the chair, and sits as soon as possible. Using the iPhone's accelerometer and gyroscope, data in three axis directions is recorded every 0.01 seconds and analyzed using a proprietary algorithm. This application was developed from the iPhone application "SENIR Quality". (Digital Standard Inc., Osaka, Japan). We created the "iTUG Score" as a new universal measure to assess gait. This score is calculated from the volume of 95% confidence ellipsoid of iTUG time and 3D acceleration time series data. This score has been verified to be reliable and relevant, and is a universal measure for assessing gait. Items that can be measured with this app ·time ・ ITUG score ・ Division graph of operation ・ 3D acceleration graph ・ 3D acceleration graph volume About preservation ・ Users save data to the cloud server. Users can retrieve data from the server and display it on the screen. ・ When guest play, the latest 30 items are saved on the terminal. ・ The latest one record is displayed on the home screen including graph data. The following iPhones and iPods cannot use this application. iPhone models released before the iPhone 5 iPod touch 5th generation or earlier

Welcome to the future of Gait Analysis! Introducing the revolutionary GaitAnalysisPLUS - for Physiotherapists, GAIT researchers, doctors, and sports coaching! This app combines our well-known and reliable Stridalyzer Sensor Insole based gait analysis with vision-based pose and gait analysis, to offer you a one-of-a-kind solution! Using the pressure and motion data from the sensor insoles, and vision data from your iPhone’s camera, the app builds an extremely accurate, real-time model of the forces, motion and position of not only the feet, but the entire body. Using that model, the app can provide exact analysis of the user’s posture, gait, biomechanical forces and its effects, etc. Use the app in your rehab session, for sports performance analysis or for gait research. The app can work with or without the sensor insoles, using only the vision data if there are no insoles connected. Please note - the app uses several features and capabilities in your phone that can severely drain your battery. 1. The app connects to the sensor insoles using BlueTooth LE. The app continue to run, will keep the connection, and will continue communicating with the insoles if connected, even in background mode with display off. This will impact the battery life of your phone. 2. The app will use your iPhone’s back camera to capture video for vision-based gait analysis. This feature will only work when the app is in foreground and open. The vision analysis uses your phone’s machine-learning capabilities, and consumes a significant amount of power. We strongly recommend using the vision analysis capability when your phone is connected to a charger cable, ideally placed on a phone holder/stand.
