iPhoneからアプリを開くと毎回なぜかApple IDのパスワードを要求されます。何故でしょうか?無視していますが、要求画面を消すのが面倒なのでやめてほしいです。もしくは元のサイトがハッキングされてこのようなことになっていませんか?

Missing features from the promised list

The following are missing:
1. Japanese pronunciation confirmation (pronunciation reading function)
2. Offline Japanese English dictionary

Basically this app is just an app version of the web-based browser version, no less or no more.

Too slow

It was glad news that weblio be available as an app. But it is too slow to use stress free especially while keyboarding. I wish it will be fixed.
