Mayerson Academy OG Card Deck is a free Android application that offers an effective and straightforward approach to learning the phonetics behind over 80 common grapheme-phoneme correspondences. This app is designed to help users understand the building blocks of reading and spelling. The multisensory experience provided by the app includes hearing the corresponding phoneme and key word, watching a video clip showing articulation of the phoneme, and the opportunity to practice the phoneme with a voice recording/playback option.

The app features a user-friendly interface with modern graphics that appeal to both children and adults. It is designed for use with Orton-Gillingham based reading programs or in conjunction with any phonics-based curriculum. It is a useful literacy tool for educators, university students in education-related fields, reading tutors, O-G practitioners, Speech-Language Pathologists, ESL learners, parents, and children. The app allows users to learn the logical sequence of multiple spellings for 21 graphically-represented phonemes and select one or more categories for each practice session, including consonants, single vowels, consonant digraphs, vowel teams, vowel + r, short vowel signals, VCe, and common suffixes. The app also features a record/playback option, allowing users to hear their own pronunciations and enhance their learning experience.
