This app is made to remember announcement dates of financial statements.
It gets the schedules from the website of Japan Exchange Group, Inc.
So you can know them with your iPhone/iPad.
And if you put a company you want to follow on "Watch List", you can get a notification on the announcement day.
Pull down "Schedule" to update it although it has been designed to get the new one automatically.
Companies in this app are only Japanese companies, naturally.
