Annoying ads now in app

This was a nice app until the integration of Google ads into it now they out flash in front of you while you’re trying to read numbers and it’s irritating. Full of porn

横表示が出来なくなった

以前は出来ていた横画面表示が出来なくなった様で、使い勝手が少し悪くなりました。
広告も以前より大分うるさくて目障りになりました。
無料で使用しているので、仕方の無い部分かとは思いますが、使いやすいだけに残念です。
