About

A Good Custom Keyboard

Features
Read full description

A Good Keyboard fixes your typos without changing anything behind your back, types your email in one tap and, with the subscription, does math right in the keyboard. NO DATA IS COLLECTED. REALLY. Unlike almost every third-party keyboard, A Good Keyboard works without Full Access. Nobody can see what you type, not even us: nothing you write is sent to us. No tracking. 50+ ANIMATIONS YOU EARN AS YOU TYPE Every key reacts under your finger, with the animation, font and key shape of your choice. The more you type, the more levels you unlock. The first 5 are free. With the subscription, every level becomes reachable. SNAPIQ: YOUR TEXT IN ONE TAP Put your email, your address or a sentence you type often on a SnapIQ key: one tap, and it’s typed. One key is free, all 26 with the subscription. A CALCULATOR IN YOUR KEYBOARD With the subscription, type a calculation or a conversion and the pill suggests the result. With the number row, the #+= key opens a calculator. NUMBERS AND THE COMMA AT YOUR FINGERTIPS With the subscription, on iPhone: a number row above the letters, gray or the color of the letters, and a comma next to the space bar. No more switching pages. A KEYBOARD THAT REMEMBERS YOUR FIXES With the subscription, a typo you keep making is taken care of in one tap: from then on, the keyboard fixes it for you. Manage the list right in the keyboard, and add your own replacements. CORRECTION PILLS THAT NEVER FORCE ANYTHING ON YOU Free for everyone. A typo, a missing apostrophe, two words stuck together because your thumb hit b instead of the space bar: the fix waits for you in a pill. Nothing changes without your OK. KEYS THAT FIT YOUR HAND With the subscription, move the boundaries between keys yourself so they follow your thumb. They come back on their own through iCloud if you reinstall the app. AND ALSO Haptics, the color of the pressed key and the accent panel delay, the way you like them. In an email field, @ and the period sit next to the space bar. A button to lower the keyboard. THE SUBSCRIPTION Without a subscription: basic features, correction pills, the first 5 personalization levels and 1 SnapIQ key. With A Good Keyboard (monthly) or A Good Keyboard (yearly): every level reachable, 26 SnapIQ keys, the calculator, the number row and the comma (iPhone), remembered corrections and manual keyboard adjustment. One-month free trial for first-time subscribers. Family Sharing included. Price and duration are shown in the app before any purchase. Payment is charged to your Apple Account. The subscription renews automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel it in your Apple Account settings.
