I understand that something needed to be done. Still can't help but say that it's a pity. A blanket ban on new users posting doesn't seem right. There are many people like me who "followed" HN for a long time, but then decided to create an account recently to post and ask for feedback, only to see the submission get blocked.
Working on Sensonym (https://sensonym.com), a language learning app that teaches vocabulary through physical phone interactions. Shake your phone to learn "earthquake," blow on it for "wind," smile for "happiness." Nearly 40 different interaction types using accelerometer, gyroscope, camera face detection, microphone, etc.
Built with React Native/Expo. The hardest part hasn't been the sensor code, but rather designing interactions that feel natural rather than gimmicky. Each word needs to map to a physical action that actually reinforces the meaning.
Solo dev, live in German app stores now. Previously co-founded another language learning startup (Sylby, partnered with Goethe Institute), so this is take two with a very different approach.
