Keep an app always on in Apple watch

Hi All, I like to develop an watch app which capture IMU data (9 axises) in 10Hz and use a ML model check an event occurred. My app should be on/run in background always. ML model also can be put in an iPhone app. I need a suggestion whether I can run app always in watch to capture the IMU data. Thanks
