Calendar function produced by Japanese developer

In the recent update, I referred to the script produced by Japanese developer. It was a long no seeing Japanese script which is useful for me since Swift became version 3.

It is said that Japanese people have detailed thinking so this may be the example that I respect and am proud of as Japanese. If you are planning to add some calendar function into you APP, it would be very helpful because there was no official ui tool from Apple about this.

Let me introduce it from respecting.
Here is the link to the web page of the developer, named Reo.

(You can refer it from your PC because iPhone App is limited to “http address”.)
