Mobile App for Typing Competition

I am in need of a talented app developer to create a mobile app specifically designed for a typing competition. The most important feature of this app should be the ability to accurately measure typing speed. Ideally, the app should have a user-friendly interface and offer precise measurements. The perfect candidate for this job is someone with prior experience in designing mobile apps, with a focus on accuracy and performance. Knowledge in latency and processing speeds is a must, as accurate typing speed measurement is at the core of this project. Your creativity and insight in translating this concept into a well-functioning app will be much appreciated.
