My very popular iOS app Simply Voice Dictation:

This is a very handy application that allows you to dictate text with your voice by speaking phrase by phrase ('Dictate Next' button). You can copy the resulting text to the clipboard ('Copy' button) and then paste it to any application. Also you can export the text to Viber, Whatsapp or Telegram messengers. If any inaccuracies appear during voice recognition, you can simply delete the last sentence ('Clear Last' button) and say it again more clearly. And of course you can edit all of the entered text using your keyboard.
2 very convenient mode added to the app: Mode : 'Aaa bbb.' Every phrase, that you say, starts with capital letter and ends with full stop. Mode: 'aaa bbb' Every phrase, that you say, starts with lowercase letter and ends without full stop . This is very convenient mode to include in the text punctuation marks, during your voice typing. After dot, next phrase will begin with capital letter.

 The application uses the most advanced speech recognition technology, providing top quality recognition for all supported languages.
 This application was specially designed to be very easy to use. Enjoy the beauty of simplicity! We’re sure that you’ll find a good use to this app!
