Big Thumb Keyboard

Stop fighting tiny keys. Big Thumb Keyboard revolutionizes mobile typing with an innovative 8-directional swipe system that puts 40+ characters at your fingertips using just 5 large buttons.

REVOLUTIONARY DESIGN

Unlike traditional keyboards that shrink keys to fit everything on screen, Big Thumb Keyboard uses intelligent swipe gestures. Each button gives you access to 8 different characters - just swipe in any direction. It's like having a full keybo

KEY FEATURES

- 8-Way Swipe System
Each alphabet button responds to 8 different swipe directions (up, down, left, right, and corners), giving you instant access to multiple letters without hunting for tiny keys.

- Consistent Physical Button Size
Buttons maintain the same physical size (5mm wide) across ALL devices. Whether you're on an iPhone SE or iPad Pro, your muscle memory works everywhere.

- One-Handed Mode
Swipe left or right on the Shift key to instantly switch to one-handed mode. Perfect for typing while holding coffee, bags, or your little one.

- Smart Auto-Correction
Advanced auto-correction learns from your typing patterns. Swipe up on Shift to toggle on/off. Includes instant undo - just backspace within 2 seconds to reject any correction.

- Quick Symbols & Numbers
Access numbers, punctuation, and special characters instantly through control button swipes. No more switching keyboard modes for common symbols.

- Haptic Feedback
Feel subtle vibrations as you swipe (requires Full Access). Different feedback for different directions helps you type without looking.

HOW IT WORKS

The keyboard uses a scientifically-designed letter grouping system inspired by Korean Hangul principles:
• Button 1 (Vowels): a, e, i, o, u
• Button 2 (Lips): m, b, p, v, f
• Button 3 (Tongue tip): s, j, c, z, y, w
• Button 4 (Tongue body): n, d, t, l, r
• Button 5 (Throat): h, g, k, x, q

This phonetic grouping means similar sounds are on the same button, making it intuitive to learn.

PERFECT FOR

- People with large fingers who struggle with tiny keys
- Anyone who wants to type one-handed
- Users with motor accessibility needs
- Fast typists who want to try something revolutionary
- Anyone tired of autocorrect failures from hitting wrong keys
