Thumboard Keyboard

A Korean (dubeolsik) keyboard laid out for where two thumbs actually land. [Unfold the phone] The keyboard splits into two islands that sit under your thumbs. Pick the size of the islands and the gap between them in three steps each, and snap the whole thing to the left edge, the center, or the right edge. Fold the phone and it comes back as one board. [The space bar stays where you put it] However you arrange the bottom row on the single board, the split boards inherit it. Put the space bar at the left edge and it is still at the left edge after the keyboard splits. [iOS paints the background] The keyboard does not paint its own tray. It uses the keyboard material the system draws, so light and dark never disagree with the rest of the phone. You can tint it with a color pulled from your wallpaper and dial the opacity. [What it does not do] · No ads, no account, no purchases · No network calls — there is not one line of networking code in this app [About Full Access] Turn it on and you get haptics and the click sound as you type, plus the app can read what the keyboard recorded on the device and show it to you. iOS ties those two to Full Access. Turn it off and typing works exactly the same — only the feedback under your thumb is gone. Either way, what you type never leaves the device.
