Big Keys Keyboard helps you type with large keys, large text, and an accessible keypad on iPhone. It is built for low vision, seniors, and anyone who wants a clearer, calmer keyboard. Make your next message easier to write and easier to trust, starting now! Keys, text, and emojis — as big as you need This is the heart of Big Keys. Adjust key size to reduce mistaps and make each tap feel more accurate. Make the typing text larger so you can confirm words faster before you hit send. And if emojis look tiny, scale them up so your favorites are easier to see and select. Your keyboard can speak Turn on Speak and hear what you type, in the language of your keyboard. Big Keys can speak every key, every word, and every autocorrection, so silent changes never slip past you. Tap and hold a suggestion to hear it before you choose it, and deleted characters and words are spoken in a lower voice so you always know what changed. Choose the voice, speed, and volume. Speak works hand in hand with VoiceOver. Built for visibility Most keyboards assume perfect vision and tiny, precise taps. Big Keys Keyboard focuses on clarity with bigger letters, clearer spacing, and layouts that feel easier to follow so you can type with less strain. A calmer keyboard experience Some people find standard keyboards visually noisy or overwhelming. This keyboard aims to feel more predictable by keeping things clear and reducing unnecessary clutter, which may help support focused typing for users who prefer a calmer layout. Dedicated keypad Need to type digits fast? The built-in keypad is there for PINs and codes, but also for phone numbers, prices, and addresses. High contrast themes Choose a look that keeps the keyboard clear and readable. Bright light can wash things out, so stronger contrast often helps. At night, a calmer theme can feel better while the letters stay easy to see. Now speaks Japanese too Type Japanese on a full kana keyboard with big keys: flick input with a large, easy-to-see guide, multi-tap input with an adjustable tap window, a dedicated kaomoji key with over 150 text faces, and Japanese word suggestions. Language support If you type in more than one language, switching should not feel like work. Big Keys supports more than 25 languages, including the new Japanese kana keyboard. Switch with a simple hold on the space bar and keep your flow across messages, email, and search. Less retyping Gesture shortcuts can help you reach the keypad or special characters faster. If enabled, haptic feedback can make key presses feel more certain, and a last key indicator can make quick corrections easier. One keyboard, made for many Big Keys helps a wide range of people type more comfortably: people with low vision or tired eyes, seniors who want larger targets, anyone with tremors or less precise fingers, users with dyslexia or ADHD who prefer a calmer layout, and kids just learning to type.

About

LeafU

Read full description

Turn scattered thoughts into structured ideas. The human mind does not think sequentially like a computer. It thinks radiantly - forming connections in multiple directions at once. Traditional lists and plain text notes can often feel limiting: they hide key ideas, make information harder to remember, and fail to engage the brain in a natural, stimulating way. LeafU is designed around a different approach to thinking. In Radiant mode, ideas grow outward into new sub-branches, helping chains of thought develop naturally and encouraging continuous creative thinking. Because ideas are linked visually, the brain can form new associations more easily - discovering unexpected connections and sparking new insights. As your ideas begin to take shape, List mode helps keep everything organised, while Text mode provides a space for deeper writing and more structured thought. Many mind mapping apps can feel overwhelming, filled with complex tools and crowded interfaces that interrupt creative flow. LeafU takes a lighter approach - focusing on simplicity, clarity, and intuitive gesture-based navigation. LeafU is designed to support your thinking, creativity, and memory - one screen at a time.
