### 4/5 — Yahoo!カレンダーからの乗り換えですが、、、

*2026-05-15, version 1.0.18*

スタンプで管理しやすいのはYahoo!と似ていていいですが、
アプリダウンロード画面では如何にも月ごとのカレンダーに見えますが、(「月」を表すバーはでますが、固定ではなく)実際は日続きのカレンダーのため、翌月以降の予定を即決が必要な時見にくい。

例えば病院とかで次回予定を決める時(ほぼ即答が必要な時)、アプリを開いた瞬間の翌月や2〜3ヶ月後の日にちや曜日が見にくい、しかもすぐ当月に戻るから曜日を見間違えることが多い。
(時間のある時は背景の月も見えるけど、急ぐときは意外と目に入らない。)

改善して欲しい点は、「月」を表示しているバーで月ごとにフィルタリング機能など、月単位で管理しやすくしてほしい。

### 5/5 — Favorite Calendar App

*2026-03-22*

I've tried so many calendar apps over the years but could never keep using them. This one is the only one I've maintained daily for almost two years now. The stickers are super cute and the ads are minimal/not obtrusive. You can easily earn new stickers and there are regular updates. Thank you so much to the dev team for a wonderful calendar app!!

### 5/5 — 可愛くて使いやすい

*2025-10-30, version 1.0.15*

スタンプカレンダー難民だったのですが、やっと見つけました！他と連動のないオリジナルで、スタンプで、かわいいカレンダー！
機能もスタンプも満足なのでずっと継続して欲しいです。応援します。

### 1/5 — 信じれない

*2025-08-29, version 1.0.15*

突然スケジュールが全て消えた。スタンプだけ残ってる。

### 5/5 — 使いやすい

*2025-06-18, version 1.0.13*

皆さんと同じYahooカレンダーの終了に伴い、こちらのカレンダーアプリにしました！色々他のカレンダーも試しましたが、使いにくかった…。理想のカレンダーに出会えて嬉しいです。
はじめは縦でしか使えず慣れるのに時間がかかりましたが、横になって大変有り難い！スタンプも少しずつ新しいのが出て可愛いのも沢山。とても使いやすく大満足です✨

欲を言えば背景のテーマも色だけじゃなく絵柄の可愛いのが欲しいです。ご検討お願いします！！

### 5/5 — 使いやすい。

### 1/5 — 削除

*2025-03-30, version 1.0.12*

削除の仕方がわからない

### 3/5 — スタンプ機能

*2025-01-25, version 1.0.12*

某カレンダーアプリ終了に伴い、極力似ているアプリを探していて発見し、試しながら使ってます。
通知有りに設定しているのですが、通知が来なくて困っています😭
何か対策法があれば教えてください🙇‍♀️

### 4/5 — 使いやすいです

*2025-01-19, version 1.0.12*

使ってるカレンダーアプリが次々と終わってしまうので、
新たなスタンプカレンダーとして使い始めました。
いろいろ改善されて使いやすくなっています。

### 2/5 — 予定開始日と終了日の日程が同一日にしかならないバグを直してほしい

*2025-01-08, version 1.0.12*

アプリの開発、定期的なアップデートありがとうございます。
概ね満足していますが、連続したスケジュールを登録出来ないのはスケジュールアプリとしてかなりイタイのでぜひタイトルに入力したバグの修正をお願いします。（例えば1月1日〜1月4日の出張の予定を入力しても、終了日を入力したタイミングで開始日も1日から4日に自動的に変更になってしまいます）
