Just use the microphone icon on your keyboard. Don't need a separate app. The microphone works on online forms, text messaging and note taking or document writing.
If you are disciplined, you can say "comma" or "period" or etc. just the way "bosses" did in the 1950's when giving dictation. Then, use search and replace to replace the punctuation word with the punctuation mark (not possible in the 1950's).

I use the microphone icon all the time, too. Punctuation commands are needed, as is careful proof-reading.
