Adam Lack, founder of Hidden City Hunts, built an interactive scavenger hunt app using Bubble's no-code platform, allowing users to play on their mobile browser without needing any coding experience. The app provides real-world and online trails with cryptic clues and hidden gems, scoring players based on points and time. With a background in the live entertainment industry, Adam discovered no-code tools like Bubble in 2016 and has been using it to build and launch his fully functional web app. Hidden City Hunts has received great feedback after its recent launch and plans to expand trail selection and develop new features with user feedback. Bubble is a leader in the no-code movement, offering a powerful point-and-click web editor and cloud hosting platform for building customizable web applications.
