Keep UP is a free puzzle game for Android developed by VTV Studio. The game is designed to help players improve their memory skills by repeating sequences of tones. At the beginning of the game, players are tasked with repeating short and easy sequences, but as the game progresses, the sequences become longer, making it more challenging.

In addition to the single-player mode, Keep UP offers a two-player mode where users can compete with each other and a challenge mode where each level has its own target that players need to achieve. With its fun and engaging gameplay, Keep UP is a great way to pass the time while also improving your memory skills.
