趣兒 is a free iPhone app developed by chihming hsu that aims to revolutionize communication between schools and parents. With traditional paper contact books, it can be challenging to relay information promptly and comprehensively to parents. Whether it's signing important documents or simply staying informed, paper contact books can be overwhelming and time-consuming to navigate.

In addition, class photo albums on various platforms can be inconvenient to use. Parents often find themselves sifting through hundreds of photos just to find pictures of their own child. Privacy concerns also arise on some platforms, where anyone can be added to group albums without any connection to the class.

The purpose of developing this software is to make information sharing easier for schools, as well as simplify the process for parents. By streamlining communication, 趣兒 aims to reduce the effort required by each party involved. The developers welcome feedback and suggestions for additional features or improvements.
