1C Big Keyboard MOD APK (Ad-Free Unlocked)

I am 58 and my vision is far from perfect. I have fingers on my hands - not matchsticks, so I designed this keyboard for myself. If you’re under 35 and have no problems with vision, please do not install. You will need it later. But maybe it will be a good lifehack for your parents now.

Improved Accuracy and Reduced Eye Strain

The enlarged keys significantly improve typing accuracy, minimizing typos and frustration. No more accidental presses of neighboring keys or struggling to target the correct letter. The increased size also contributes to a more comfortable typing experience, reducing eye strain and fatigue, especially during extended periods of use. This is particularly beneficial for users with vision impairments or those who simply want to minimize the strain on their eyes while texting, emailing, or composing documents on their phone.

Intuitive Layout for Easy Learning

Despite its unconventional full-screen approach, the 1C Big Keyboard maintains a familiar QWERTY layout. The traditional arrangement of keys is intelligently compressed to accommodate the larger size, ensuring a smooth transition for users accustomed to standard keyboards. This design choice eliminates the need to learn a new layout, making it instantly accessible and user-friendly.

Accessing the Full-Screen Mode

Activating the 100% display mode is simple and intuitive. A quick upward swipe on the keyboard instantly expands it to fill the entire screen, transforming your phone into a spacious typing interface. This gesture-based activation ensures seamless switching between the standard and full-screen modes, allowing you to adapt the keyboard to your specific needs and preferences.

Ideal for Large Hands and Small Screens

The 1C Big Keyboard is particularly beneficial for individuals with larger hands who often find traditional smartphone keyboards cramped and uncomfortable. The increased spacing between keys provides ample room for accurate typing, eliminating the frustration of accidental presses and typos. Additionally, users with smaller phones or those who simply prefer a more expansive keyboard will appreciate the ability to maximize screen space for a comfortable and efficient typing experience.


In summary, the 1C Big Keyboard for Android is a practical solution for anyone who struggles with typing on small screens or has larger fingers. By offering a full-screen keyboard mode, it provides ease of use, reduces eye strain, and minimizes typos, all within an intuitive layout. Whether you’re using a small device or have large hands, this keyboard is a valuable tool for improving your typing experience.
