About

Read full description

This keyboard is designed for real mobile users who type with one thumb. It supports standard mode, left-handed mode, and mirror mode so you can choose the layout that feels most comfortable for your hand. The smart thumb layout reduces finger movement and helps you type faster with less effort. * Vowels and consonants are placed in separate zones, and consonants are grouped by similar pronunciation to make keys easier to find with one thumb. There is no learning curve. You can start typing naturally from the first use. It also includes a built-in calculator. You can quickly calculate numbers without leaving the keyboard, making it useful for shopping, work, and daily tasks. Use it for just 5 minutes a day for one week, and you will not be able to go back to the old QWERTY keyboard. Switch modes anytime depending on how you hold your phone. Whether you are right-handed or left-handed, this keyboard adapts to you. Designed for speed, comfort, and real-world use on smartphones.
