Changy is a free Android application developed by 4CODE, falling under the Business & Productivity category. This app aims to connect professionals looking to exchange work opportunities with ease.

Users can create their profiles by entering their name, surname, and role. They can then submit their transfer request by providing details in three simple steps: current workplace, desired transfer location, and alternative exchange options. This information assists the Changy team in finding suitable work exchanges for the users.

The app features an interactive Homepage where users can browse through colleague requests tailored to their preferences. Additionally, users can search for peers with similar roles and directly contact them to arrange exchanges. With the "Direct Exchanges" feature, users can explore pre-planned exchanges suggested by Changy.
