"Daily Brain Training" is a free brain training app that offers a variety of exercises to improve memory and calculation speed. The app provides several features to enhance the training experience.

One notable feature is the ability to create separate save data for up to four users on a single device. This makes it convenient for families to use the app together and track their individual progress.

The app also incorporates a training level system that adjusts the difficulty of the exercises based on the user's accuracy. As users answer questions correctly, their training level increases, allowing them to engage in more challenging brain exercises.

The score is influenced by the user's training level, so the more they train, the better their score can be. Additionally, users can share their scores on social media platforms like Twitter and Facebook.

To keep track of their progress, users can access a training calendar that shows the number of exercises completed each day. The app rewards users with stamps for completing more training sessions, providing a visual representation of their achievements.

The current version of the app offers a wide range of exercises, including serial calculation, card memorization, shape recognition, and more. The developer plans to add new trainings and features in future updates to keep users engaged and entertained.

Overall, "Daily Brain Training" is a comprehensive brain training app that offers various exercises to improve memory and calculation skills. With its user-friendly interface and engaging features, it provides an enjoyable way to challenge and stimulate the brain.
