User reviews

サーバーへの接続が…

リーダーの機能としては問題ないですが、、、
FTPSに繋がらないし、
HTTPSのせいなのかTLSのせいなのか証明書のせいなのか、WebDAVにも繋まともにがらない…

その他の接続も仕様が古いみたいですね。
とても残念です。

大々的なアップデートが必要です。

音声が

散歩中にテキストの読み上げをしてもらっていましたが、iOS26になったら音声が劣化してしまいききにくくなりました。
修正入るといいなと思ってレビュー入れさせていただきます。
お気に入りのアプリです

ちょっとした不具合

iOS26で画面がダークモードの時、本棚を上下にスクロールすると本棚名が表示されている上部と画面切替のボタンがある下部が黒色から白色になります。
OSのバージョンの問題ですが、できれば修正してもらえると嬉しいです。

NASに入れない

Nasに入れるということで購入、入れないとわかり即使用を停止しました

SMB 1しか入れない等の話だと思いますがさすがに使い物にならない

お金をドブに捨てました
