KeyNounce is a free iOS app developed by Abdulla Al-Shurafa that allows users to type in Hindi using just the English keyboard. It uses transliteration to convert the English pronunciation of a word into its Hindi counterpart, making it easy for users to type in Hindi without having to worry about the exact spelling of each word. The app is simple, fast, and highly accurate.

With KeyNounce, users can easily compose texts, emails, tweets, Facebook posts, and search the web in Hindi. It works seamlessly in any app once the keyboard is enabled. If you can read or write Hindi but are not used to typing using the Hindi keyboard, KeyNounce is the perfect solution for you. It is a must-have app for anyone who needs to communicate in Hindi on their iPhone.
