Overview
- Anton Baranov, a 22-year-old student from Frankfurt, was named one of Apple’s WWDC developer competition winners on Monday for his app Pitch Coach.
- Pitch Coach listens to speech to flag filler words, suggests speaking tempo, and uses AirPods motion sensors to monitor posture during rehearsals.
- All analysis and AI models run on users’ iPhones rather than in the cloud, so audio and motion data do not need to be uploaded to external servers.
- Baranov used artificial intelligence to localize the app into more than 20 languages, currently offers the app for free, and says he may add paid subscription features later.
- Baranov studied in a dual program in Germany, received public praise from Apple CEO Tim Cook, and his win highlights how student developers can use AI and device sensors to build privacy-minded tools.
