What's a good iOS app for improving my writing and grammar on my iPhone?

Grammarly: AI Writing Keyboard is a helpful tool for anyone who wants to improve their writing on their iPhone. It functions as a keyboard that integrates with various apps, checking your grammar, spelling, punctuation, and style in real-time as you type. This is especially useful for composing emails, writing social media posts, or drafting documents directly on your mobile device. The app provides suggestions for correcting errors and improving sentence structure, which can help you communicate more effectively and confidently. Over time, using Grammarly can also help you become more aware of your writing habits and make improvements independently. It offers personalized feedback, explaining the reasoning behind each suggestion, thus enhancing your understanding of grammar rules. The app also lets you adjust settings to match your writing style and preferences, making it a valuable tool for both native and non-native English speakers.
