Spent half a day handcrafting an app. Web version tested, mobile version completed, and all APIs are connected to the production environment—ready for use. Features: Plan walking routes based on user preferences (time/theme/goals), helping you explore the city and enjoy the fun of walking. I’m a hardcore walking enthusiast, so I built this little toy based on my own needs. The efficiency boost AI brings to creating a small test product is truly mind-blowing. Take the front-end UI, for example. Image 1 shows the UI I tested on the web version, but it’s completely unusable when moved to the mobile version. Back in the day when I was working on products, communicating with the tech team to change it to the mobile layout in Image 2 would’ve required back-and-forth discussions with tech/UI/UX, confirming schedules, and at least three days of development. With AI, I just gave one request, and it was done in 3 minutes.
