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.

I built "Are You Sure" because I wanted a simple way to reduce my screen time. Essentially I was looking to help break a common loop... I would pick up my phone to check something, and twenty minutes later, I'm halfway down a rabbit hole without an intent. So I wanted to build a tool that didn't just "block" apps, but instead helped me document and understand why I was opening them in the first place. How it works: When you try to open an app you’ve locked, "Are You Sure" gently interrupts that habit loop. It asks you a simple question: "Why do you want to use this app right now?" You type your reason, and then (facing your own reason) you get to decide: Are you sure? Features: The Conversation: Your history with each app is stored as a private chat with yourself. Seeing your past reasons is meant to help you spot patterns and decide if that "quick check" was actually worth it. Active Sessions: When you do decide to unlock an app, you get a set amount of time. Once it’s up, the intention loop starts again. Privacy First: There are no accounts and no tracking. Your data never leaves your device. It’s your history, for your eyes only. Purely Helpful: No ads, no paywalls, and no annoying notifications. The app stays in the background until you need it. I built this for the fun of learning and for the benefit of reducing my own screen time. I hope it helps you find a little more space in your day for the things that are meaningful to you. And if you find it helpful, there’s an option to leave a tip, but the app is (and always will be) fully free to use. Thank you for checking this out, Ant
