A wonderful learning experience
The educational concept of the Correct Writing app is based on having the words spoken aloud, then spelled out in full using an expanded range of letters and inserted into sentences. Listening, writing the words in full, and referring to the quote or proverb provides intensive spelling and memory training.
For middle-aged or older people
The app is aimed at middle-aged and older individuals and helps them train their memory, attention, and concentration through targeted spelling exercises. The main goal is for adults and seniors to remember the corrections to their mistakes and, through memory training, maintain and strengthen their cognitive abilities.
