以前はTwitterに起床時間や中途覚醒が通知されてましたがその機能Xで投稿できるようにして欲しいです
それが一番の目的で使っていたのでガッカリです
それ以外は何も問題はないのですが···ただのアラームならiPhoneのアラームだけでいいです

設定した時間に音はならない、設定通りの音量で鳴らない

かれこれ4年以上使ってますが、目覚ましがならないことがあるため、iPhone2台で目覚ましをセットしております。

さらに片方のiPhoneは時刻通りなるが超爆音(iPhone7)
もう片方のiPhoneは設定した時刻から1分ほど遅れてから鳴る、スムーズでも同じ挙動をする(iPhoneSE2)ため少しずつアラームの時間がズレていく、5分後にセットしても6分後に鳴る目覚ましってどうなんだろうと思いながら使うことが多いです。

鳴らない時の原因の9割がiPhoneの自動アップデートです。
夜中に電源が落ちると、目覚ましを中止にするとかいう素敵な仕様になってました。

いままでありがとう

ココ最近になってからバックグラウンドで電池をめちゃくちゃに消費するようになった。発熱も凄いため一先ず消すことにした。非常に残念に思う。

使いやすいが‥

起きた後バックグラウンドに残すと電池を消費し続けることがあるようだ。

Apple Watchでも対応して欲しい

録音機能やApple Music対応で満足度高いです!

枕元にiPhoneがあると触ってしまうので、Apple Watchで録音解析できるようになって欲しいです。
