Clink is a custom keyboard for iPhone and iPad. Choose how it looks, arrange the keys, change the sounds and keep useful tools close to where you type. Start with a preset you like, or make a keyboard of your own. Choose a simple theme, metal keys, raised 3D keycaps or translucent Liquid Glass. Change colours, fonts, gradients, outlines and key shapes. Set separate themes for Light and Dark Mode. The live preview lets you type while you make changes. Add a photo background or put artwork on individual keys, with framing controls to get the placement right. Canvas mode lets you edit each key. Export your theme to share it, or import one someone else has made. Choose QWERTY, AZERTY, QWERTZ, Dvorak or a layout for your language. Try Clink Flow for two thumbs. Add a number row, use a split keyboard or switch to one-handed mode. Adjust height, width and spacing, and add custom keys and rows for text or functions. Tap or swipe to type. Two-thumb word composition lets either hand continue the same word, combining taps and glides. Keep a simple swipe trail or choose one with colour, sparks or a comet tail. Autocomplete, autocorrect and swipe decoding work on your device, without an internet connection. Clink can learn your words and the corrections you reject; learning can be switched off or reset. Text replacements, smart punctuation and automatic capitals help with everyday typing. Use combined suggestions for multiple languages or keep them separate. Clink includes Japanese kana, Chinese Pinyin and Korean input, with language packs available to download. Features depend on the language and installed resources. Slide on the spacebar to move the cursor, or use trackpad mode for more control. Adjust sensitivity and activation timing to suit your hands. Predictive flick lets you accept suggestions directly from the keys. Clipboard history keeps saved clips in groups. The notepad holds text you want to use again, and the calculator handles quick sums and conversions. Find emoji with search, recent choices and skin tones. Arrange the panels around what you use. Use dictation when you would rather speak, handwriting to write with your finger, or translation to prepare text in another language. Supported translation works offline after its resources are downloaded. Dictation may use Apple's speech services. On compatible devices, writing tools use Apple's on-device models to proofread, rewrite, shorten, expand or summarise text. Change the tone or prepare a reply, then review it before use. Apple Intelligence support and downloaded models are required. Choose a system click or sound pack, set the volume and tune the haptics. Adjust how keys move and respond. Add lighting, stickers or a small pet that reacts as you type. Save setups as profiles and switch between them from the keyboard. Optional iCloud sync carries profiles and custom themes between devices. Text clipboard history and learned vocabulary sync are separate choices, both off by default. Build custom actions for repeated tasks or write a panel using the built-in Python subset. Add compatible theme, layout, font and sound packs to extend your setup. No Clink account, ads or cross-app tracking. Ordinary typing does not send your text to a server. Core typing works without Full Access; clipboard access, haptics, custom sounds and shared settings use that permission. Downloads, purchases, iCloud and some speech features need a connection. Requires iOS 17 or later. Liquid Glass, translation and Apple Intelligence features depend on your iOS version, device, language and available resources. Setup walks you through adding Clink in iOS Settings. Switch to it with the globe key wherever custom keyboards are supported.
