Curio-QA

Curio-QA is a QA app that allows its users to send curios to all of its users. With this app, its users will be able to send and receive their questions in the form of curios. The receiver could answer the curio on any platform they like and then mark the curio as answered.

Currently, this app is only a web service that can provide its services via REST API. For real-life implementations, a client should be created. Thanks to the advantages of REST API, this app can be used in mobile apps, desktop apps, and web apps.
