I am grateful. ### 5/5 — おすすめです。 *2026-04-13* 月の画像が立体的で、キレイです。 ### 3/5 — メモが書いてもアプリを閉じたら消える *2026-03-22* メモ代わりに使っていたら突然書いた内容と少しだけロック画面やホーム画面に戻ると全て消えてしまい毎回書き直しをしてます…月を見るのも便利なので活用してるのですが…このバグを治してください…今月の15日から発生してます…お願いしますからアップデートで改善頼みます🙇 ### 1/5 — メモが消えました *2026-03-22* 1週間くらい前まで、きちんと保存されていたメモが突然消えてしまいました。 とても大切なメモだったのでショックです。 ### 2/5 — おちる *2026-03-02* 全然使えません。 どうしたらいいのでしょう。 ### 1/5 — 全く使えません *2026-02-25* 使えなくなりました。 すぐに表示が落ちて、見れません。 ### 5/5 — 良いです🙆 *2026-02-22, version 1.3.2* 月が分かりやすいです。大きくて見やすいです。 ### 1/5 — 起動しない *2026-01-26* ウィジェットの表示がおかしかったので、アプリを起動してみようと思ったら全く起動しなかった…(^_^;) ### 1/5 — アプリが落ちる *2025-12-24* 今までずっと使えていましたが、最近アプリを開いてカレンダーが表示された瞬間アプリが落ちます。毎回です。 これは改善されますか？ 課金もして使いやすくしていたのに、本当に残念です。 ## Frequently asked questions about Simple Moon Phase Calendar ### What information does Simple Moon Phase Calendar show?
