### 3/5 — いじわるやなぁ。

*2025-06-13*

プレミアム解放したならフォントも全解放してくれてもいいのにぃ。下衆いなぁ。
せっかく良さそうなアプリ見つけてもあとから金金金イケズが過ぎる。ただでさえiPhoneてフォントアプリも少ないし、製作者が日本人じゃなかったりで選ぶのが大変なのに。

**Developer response:** 貴重なご意見をいただきありがとうございます。
フォントの解放につきまして、いただいたご意見は今後の改善の参考にさせていただきます。

また、最新のアップデートでは新たに PDF印刷機能 を追加いたしました。
より快適にご利用いただけるよう、今後も機能の充実と改善に努めてまいります。
引き続き写真日記をどうぞよろしくお願いいたします。

### 1/5 — Lost all my entries!

*2025-02-02, version 3.9.0*

I backed everything up before transferring to a new phone & tried to restore but have lost everything! Please help???

### 2/5 — 改善のお願い

*2024-06-16*

① 毎年行事を 次期の日付に変更する際 最低 1年後に変更できるようにしてもらいたい。
その時 出来れば もう少し 簡単に変更できれば なお 良いと思います。
是非 よろしくお願いします。

### 5/5 — テーマごとの日記を何冊も追加できる

*2024-06-09*

私は「日々の出来事日記」「食事日記」「夢日記」「スクラップ日記」「備忘録」の5冊を作ってます。写真も６枚までつけることができるのでとっても便利です。
テーマごとに管理できしかも検索機能もあります。低料金でこれだけ楽しめるのはとってもお得‼︎おすすめのアプリです。

### 3/5 — やや複雑？

*2024-03-11*

もっとシンプルにして欲しい。

### 1/5 — Hahaha lol

*2024-01-30, version 3.4.3*

Bad joke, what is that?

### 1/5 — Multiple Journals does not work

*2024-01-18*

I paid for premium but can only post to one timeline. You can’t actually make two separate journals with separate timelines. Refund my money!

### 2/5 — バックアップ時制限？

*2023-12-23*

登録して便利に使っていたのですが
バックアップから復元する際に写真
の枚数が100枚になっており過去の
写真が見れなくなりました。

日記に写真を追加して、再度バックアップ
しても変わりません。
これは仕様でしようか？
枚数制限あるなら記載いただきたいです。

**Developer response:** いつも写真日記をご利用いただきありがとうございます。 バックアップ復元の不具合ですが、最新のアップデート (3.9.8) で修正済みのため、再度作成済みのバックアップの復元を実行いただけますと幸いです。お手数おかけしてしまい申し訳ございませんが、よろしくお願いいたします。

### 1/5 — 同作者のSimpleDiary(つぶやき日記)と比較して

*2023-10-28*

推し活の自分用まとめ日記を作りたく、最初はつぶやき日記の方をプレミアムで購入し、その後こちらの写真日記を見つけました。
試しに使い比べてみたところ、仕様はほぼ同じようですが、載せた画像の劣化がこちらの方が少なかったため、こちらに乗り換えようと思いこちらもプレミアムを購入しましたが、アプリのテーマカラー変更が思ったようにいきません。
カラー選択画面で選んだ色と、実際の色に齟齬が出ます(赤を選んだのに隣のマゼンタになる、スワイプしていくと青だったはずの選択部分が茶色になる、スワイプで変な色に飛んで移動…など)。表示が追いついていない？？再起動しても変わらず…。
つぶやき日記の方はこんなことがなかったので残念です。使い勝手が揃っていないのは使用人数の違いでしょうか？？同じ方が作っていて写真日記の方が買い切りとはいえ高値なのでとても残念です…
