設定に時間はかかるようになった

ソフト自体はとても良いのですが、セット時ソフト導入宣伝一旦移行されるのは毎日うんざりしています　欲しい時には検索するから余計なお世話です検索す

Gerade für kleines Geld die werbefreie Version geholt

Ich hatte Sleep Cycle bis heute genutzt, leider gab es dort immer mehr Einschränkungen und immer mehr Werbung trotz einmaliger Bezahlung.

Bei dieser App scheint alles zu stimmen, sogar die Restzeit bis zum Aufwecken wird angezeigt.
