Grammar Checker: iOS Writing Enhancement App

Clear and accurate writing is essential in today’s digital world. To support students, professionals, and everyday users, I developed Grammar Checker, a native iOS application designed to help users instantly detect and correct grammar, spelling, punctuation, and sentence structure errors—resulting in more polished and confident writing.

Many mobile writing tools are either too basic or overloaded with unnecessary complexity. Users needed a simple, fast, and reliable iOS-native solution that could:

Accurately detect grammar and spelling mistakes

Highlight punctuation and sentence structure issues

Provide clear, easy-to-understand correction suggestions

Improve writing without disrupting workflow

Deliver a smooth, native iOS experience

Built from scratch using SwiftUI and a modern MVVM architecture, Grammar Checker delivers a clean, responsive interface optimized for iPhone and iPad, ensuring high performance and usability.
