Forest 專注森林 - 特別版 is a productivity app designed to help users improve their focus and efficiency, especially during exam preparation. Developed by SEEKRTECH CO. LTD., this app has been ranked number one in productivity tools in 157 countries and has over 40 million global users.

The app uses gamification to make focusing more fun and engaging, allowing users to plant a virtual tree while studying. If the user leaves the app to browse social media or other apps, the tree withers away. In addition, the app offers features such as flexible timing, precise recording and tracking, deep focus mode, and online multiplayer tree planting.

The app is available for iPhone and iPad and is free to use until December 31, 2022, although the developer may extend or shorten this date. Users who want to experience more features can download the paid version of Forest. However, the app cannot detect which app the user is using due to iOS system limitations, meaning that the app cannot implement a whitelist feature.
