History
Hardware Prototype Creation
I needed to study English for work. However, every English app required multiple taps to start learning, forced me to watch ads, or had unnecessary gamification, making them difficult for me to use. So, I thought it would be great to have a device that automatically displays English just by placing it there without tapping, so I outsourced and prototyped an automatic English-Japanese display device. But the cost was high, and hardware updates were difficult. So it was left as is. Of course, I thought about a smartphone app, but I didn't have much coding knowledge. I didn't have time either. Then came coding AI.
Development Started
Using Golden Week, I asked GPT, 'I want to make an English learning smartphone app, what should I do?' From there, I bought a MAC and development began. In the beginning, the style was copying and pasting code written by GPT Oboe and Gemini into VS Code.
