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.

Ensuring you get enough essential amino acids - complete proteins - every day is crucial for everyone. However, it can be particularly challenging if you are vegan, vegetarian, or have increased protein needs due to intense exercise or bodybuilding. Why Protein Aid? Protein Aid is a great tool for: 1. Vegans and Vegetarians: Worried about your protein intake? Double-check if your food habits provide sufficient protein. 2. Climate-Conscious Individuals: Want to limit your meat intake and ensure you get enough complete protein on plant-based days? We’ve got you covered. 3. Athletes and Fitness Enthusiasts: High protein needs? Ensure you’re meeting your requirements for optimal performance and muscle building. 4. The Curious: Those who just want to find out more about protein, in which food you get it, and in what amounts. How It Works Our advanced algorithms calculate your individual Recommended Daily Intake (RDI) of Essential Amino Acids (EAA) based on your weight, age, exercise level, and other factors. As you log your daily food intake, Protein Aid analyzes the amino acid content and advises on what and how much more you need to eat to achieve sufficient complete protein intake. We also consider any allergies or dietary preferences. Reliable Sources Our calculations, including your RDI, are based on information from trusted sources such as the World Health Organization (WHO), the U.S. Food and Drug Administration, and the Swedish Food Agency. Addressing Vegetarian Protein Sources Most vegetarian or vegan protein sources lack one or more essential amino acids and need to be supplemented with other foods to ensure complete protein intake. For instance, peanuts are rich in protein but lack certain essential amino acids. This often requires knowledge of beneficial combinations, which can be challenging. Another example is the combination of rice and lentils, which is widely regarded as a complete protein source when combined. This however is not entirely true from a scientific perspective. Prevent Essential Amino Acid Deficiency Adequate intake of essential amino acids is vital for your health. Deficiency can lead to fatigue, muscle weakness, compromised immune function, weight loss, digestive issues, and skin problems. Protein Aid provides tailored recommendations to help you supplement your meals and meet your daily amino acid requirements, reducing the risk of deficiency. For Fitness Enthusiasts Engaged in rigorous exercise or muscle building? Then you have higher protein needs. Relying solely on animal proteins can be costly and unsustainable, as are large amounts of protein supplements. Vegetarian protein sources are a valuable supplement but need to be balanced correctly to maximize both muscular function and growth. With Protein Aid, you never have to worry about getting enough complete protein again. What Protein Aid Is Not While Protein Aid helps you achieve your protein and amino acid needs, it does not calculate other nutrients such as vitamins and minerals (like iron).
