What It Is

Big Keyboard is a third-party custom iPhone keyboard from Rocketship. Its main goal is not smart writing or AI input, but improving visibility and tap accuracy through larger keys and stronger contrast. The page says its keys are 40% larger than the system keyboard, with 100% higher contrast, and that each key is fitted onto a single screen. It is aimed at users with low vision, limited mobility, or anyone who wants a more accessible typing experience.

Core Capabilities and Use Cases

Based on the available content, Big Keyboard does not disclose any AI model, generative capability, smart autocorrection, or predictive input feature. It should therefore be categorized as an accessibility input tool rather than a typical AI app. Common use cases include elderly users or low-vision users who struggle to see the system keyboard, people with reduced hand dexterity who frequently mistap, and everyday iPhone typing scenarios where a high-contrast interface is preferred. After installation, users need to go to iOS Settings under General > Keyboard > Keyboards > Add New Keyboard to add the third-party keyboard, then enable it via the keyboard switch key.

Pricing, Privacy, and Integrations

The page clearly states “Install for free,” but does not specify whether there are in-app purchases, subscriptions, or premium feature limits. On privacy, the page provides a Privacy link, and a quoted review says the keyboard “does not require full access,” which is a positive signal for a third-party keyboard. However, the main text does not further explain whether data is processed locally or whether typed content is collected. Technically, the product is built on Rocketship’s Keyboard Kit framework, but there is no indication that Big Keyboard itself provides an API or external integrations.

Pros, Cons, and Best-Fit Users

Its strengths are clear positioning and simple, direct functionality, with obvious value for low-vision users and people prone to mistaps. The setup steps are also described fairly specifically. The limitations are mainly around limited disclosure: there is no explanation of Chinese input support, no information about Android or iPad support, and no details on maintenance status, customer support responsiveness, or full pricing. If users need AI input, Chinese word suggestions, grammar rewriting, or a multilingual smart keyboard, Big Keyboard is not a good fit.

Access from China and Alternatives

The site and App Store availability in China, regional download restrictions, and payment methods are not explained in the main text, so accessibility from China is unknown. Alternatives include iOS built-in accessibility options such as display zoom, system keyboard settings, as well as Gboard, SwiftKey, or other large-font keyboards and accessibility-focused input methods.
