ReadUp by Glifing is a game for children and adults. It is aimed at children between 6 and 12 years old who are learning to read or want to improve their reading comprehension. It can also be used as a complementary application to those already used by schools to teach reading.

Children with 4 or 5 years who have a knowledge of letters can also play and learn.

The game is divided into reading levels. Each level includes 30 missions, and at the beginning of the game, a level test is carried out to determine what reading level the child has.

In each mission, the child is required to complete a series of activities, such as recognizing a picture that will help them learn the sound of the letters, completing a word, or writing and decoding a word, which is an important step in the process of learning to read.

The game also includes a section with a friendly character, the ReadUp dragon. This character is the mascot for the child and provides instructions to the adult or tutor on how to carry out each of the missions.
