Hey guys. I made this keyboard extension for myself. Yes, I am a big thumber just like yourself and constantly suffer from making typos every 5 words I type. I just don't understand how "I liked" can turn into "I lied" without me noticing it, but that happened more than enough and put me into a really rough spot more than once. So I first looked around the App Store for a keyboard that would help me out to avoid any of those typos I made in the past, but sadly it seemed that no one cares about us and it was impossible to find the right one. We big thumbers just had to suffer all day, every day with these tiny little keyboards Apple gave us. So I said to myself, "I can't take this anymore" and got myself into making this cool keyboard extension named BigThumbs. That's the wholesome story behind BigThumbs and yes it just makes sense for us big thumbers since the spacing is generous and keys are just bigger and better. It'll take you about 10 minutes of getting used to using this, and I promise you it will significantly lower your chances of giving birth to typos into this world. One-time payment, no monthly subscription fees. And no, we don't collect or store any of your personal data—privacy first. I hope you enjoy it as much as I do and let me know if you have any questions regarding BigThumbs. Feel free to reach out—I'm here to help.

About

Type Korean with one thumb — and learn Hangul while you do. Hold a consonant and pull the way the vowel is written. Pull ㄱ right and you get 가. Pull it up and you get 고. There is no vowel side to cross to, so your thumb stays where it is. Tap for a final consonant, pull for the next syllable. Those two lines are the whole rule. Because your finger says which one you meant, the keyboard never guesses — and nothing you have already typed changes shape behind the cursor. ■ How it types ㅏ is a vertical stroke with a mark to the right, so you pull right. ㅗ is a horizontal stroke with a mark above, so you pull up. The shape of the letter is the direction of your thumb. Because a vowel arrives with the consonant that carries it, one gesture makes a whole syllable. ■ It stays where your thumb is Every vowel is reached from the consonant key itself, so your thumb doesn't travel — and no shift trip for tense consonants: press ⇧ and pull, or double-tap. One-handed mode moves the keys to either edge, and you can set the keyboard height — on a large phone that decides whether one hand is enough. ■ It doesn't guess No autocorrect. No word suggestions. No learning what you write. What you type is what you get, every time. ■ It doesn't take anything Nothing you type is stored. Nothing is sent anywhere. There is no networking code in this app at all — turn on airplane mode and everything still works. To fit the pull distance to your hand we count how far and which way your gestures go — never which letters, and never off your phone. ■ Learning Korean? The gesture itself teaches the structure: pulling ㄱ right is "consonant + ㅏ" written with your hand, and a separate tap is what a final consonant is. Practice comes in four stages, from simple pulls to full sentences, with each word's meaning beside it — 화장실, 얼마예요, 카드 돼요. ■ What you can change · Pull sensitivity, or let it measure your habits and set itself · How long a linked pull stays open (하하 vs 햐) · When haptics fire and how strong · Keyboard height and skin · Hand fit — we watch where you actually land and move the target under it From the app or from inside the keyboard, either way. ■ Pick a layout Four, switchable any time in Settings. · PullKey — pull a consonant and the vowel attaches. · Simple vowels — 2-set minus ㅑㅕㅛㅠ, so every key grows. Those four come from tapping a key twice, quickly. · Mui — simple vowels minus ㅌ and ㅍ; twenty keys. · Standard 2-set — the same layout as the stock iPhone keyboard. Until PullKey feels natural, use the one you know. ■ Pick how it looks Fifteen colours and thirteen quiet pictures. Each one is drawn as a small keyboard, so what you pick is what you get. On a picture you also choose how solidly the keys sit on top of it. ■ Also · Latin letters, numbers, symbols, emoji · Pull space sideways to move the cursor, up to switch Hangul/Latin · Pull delete left to erase a word, up to erase to the end of the line · Save phrases with a title, enter in one tap; {오늘} {시각} fill in date and time · Abbreviations — only pairs you wrote, expanded on space · Optional row above the keys — Hanja, kaomoji, calculator, romanize, swap 한/A, date math · Five key sounds, three loudness levels · Number row; two spaces for a full stop ■ Free and Pro The keyboard is free: all four layouts, Latin and symbols, sensitivity, hand fit, one-hand mode, haptics, cursor pulls, word delete, typo guard and practice. No trial, no expiry. PullKey Pro opens looks and extras: · Themes — 15 colours, 13 pictures (three free) · Six fonts, five key sounds · Toolbar — phrases, Hanja, calculator, kaomoji, romanize, swap 한/A, date math · Abbreviations, phrase placeholders, the Lab $6.99 once, yours for good.
