Oneカレンダー

1ヶ月間の予定を時間まで、1画面で確認できるカレンダーです! ●これに当てはまる方におすすめです!! ・バイトの予定を管理するために紙の手帳を買って、マンスリーのページのみ使っていた ・予定の詳細を表示したり、スクロールしたりせず、1ヶ月間の予定の時間まで1画面で確認したい ●このアプリは学生時代のバイトを思い出して作りました。 バイトのシフトを管理するために、1cmくらいの厚さの紙の手帳を買っていました。しかし、使っているページはマンスリーのページのみでした。予定の書き方はバイトの「バ」に19:00~22:30の勤務で、「バ19-22:30」などと書いていました。友達も同じように書いていたので、1ヶ月の予定を時間まで1画面で確認できるものがあれば嬉しいのでは考え、このアプリを作りました。 共感してくださる方、興味のある方は使ってみてください! 今後として、現状が最小限の機能のため、良いアイデアがあれば追加していきたいです。
