Is not it hard to make a list with a smartphone? I have not used the smartphone for making a list so far. I have made a list by handwriting. That is because it is earlier. However, rather than going shopping with a handwritten memo, would not it be nice to be able to utilize smartphones in a more convenient way? Therefore, I created a application that makes a list by voice. Just press the voice recognition button and speak to your smartphone like “Apple Banana Orange ...". Since a list is created by automatic line feed, there is no need for line breaks. Therefore, you can make a list overwhelmingly faster than handwriting. In addition, as it adopts genuine Apple’s high-precision voice recognition software, there is little misrecognition. You can download it for free. “Notes” 1. To use voice recognition, you need to connect to the Internet. 2. Voice recognition can be used for up to 1 minute continuous use.
