서일 영어 SAP is a mobile application that offers Phonics Champ, Core Study, and Fun Tales programs for learning English. With a single ID, you can log in to the app's PC version and choose between two packages. The app provides access to a camera, microphone, and storage space for recording and submitting your performance or for repeating sentences and words for practice.

The app requires permission to access your camera for recording and submitting your performance in SONG or TALK learning. It also needs access to your microphone to listen to your pronunciation and provide feedback during sentence and word repetition practice. Lastly, the app requires access to your storage space to save your learning data.

The 서일 영어 SAP app is an excellent choice for those who want to learn English in a fun and interactive way. Its features are easy to use, and the app provides a seamless experience. The app's permissions are necessary for its functionality, but you can still use some of the learning features even if you don't grant access to all of them.
