PhyOSC is an application that supports your exercise with Apple Watch, controlling the sound according to your body movement. Instead of uniform music at the sports gym, The instructor's improvisational movement enhances the atmosphere of the venue during the session. ------------------------- Features of PhyOSC ------------------------- 1) PhyOSC receives Core Motion data from Apple Watch on iPhone. The iPhone converts this sensor data and 12 types of arm movements trained by machine learning into OSC messages and sends them to the IP address and Port number to which the DAW is connected. 2) PhyOSC can apply a digital filter when converting Apple Watch Core Motion data received by iPhone into OSC message data. 3) OSC can name and save the filtered settings. This setting can be instantly recalled and switched, so even with the same arm movement, setting A produces a cheering sound effect, and switching to setting B produces a drum kick sound. It realizes a variety of expressions such as changing the waveform of the oscillator and the oscillator. In addition, the TCP / IP address and Port number of the OSC message destination are set in the settings, so you can switch DAW devices by switching the settings. ------------------------- System Requirements ------------------------- PhyOSC requires iPhone and Apple Watch. The required operating environment is as follows: Apple Watch : watchOS 8 Apple Watch Series 5 or higher recommended iPhone: iOS 15 iPhone 8 or higher recommended ------------------------- Limitations ------------------------- The accuracy of machine learning recognition is not 100%. Incorrect results may be output depending on the speed and angle of arm movement. We continue to research the latest research and look for new approaches to improve accuracy.

Afterday helps adults through separation, divorce or a breakup, and the adjustment afterward. Open it when you are having a hard time, when something difficult is coming up, or when you want to enjoy life again. Each choice leads to a way of coping you can use today. I'M HAVING A HARD TIME Choose what is closest: missing them, a mind that will not stop, a house that feels empty, or anger. Answer one question, then try a short sensory exercise, write down what is on your mind, or pick a small action away from the screen. Afterday is written for nights when you feel lonely, anxiety before a difficult conversation, and grief after the end of a marriage. SOMETHING DIFFICULT IS COMING UP Choose the situation (a legal day, a family date, an evening on your own), when it happens and the kind of support that would help. Afterday suggests a short plan for before, during and afterward. Edit it until it fits your life, then find it on the home screen when the day comes. I WANT TO ENJOY LIFE AGAIN Explore ideas for your home, friendships, hobbies and rest. Pick one thing and decide when to try it. Afterward, try it again or choose something different.
