Easy to use

As a new user I played around with this app for a few minutes and learned how to do everything I expected from it. For me, the ease of use and the search feature makes this a 5 star app

使い心地最高　日記や自分のためだけの詩集作成に

ページを捲れるタイプのメモアプリを探していたところ、このアプリに辿り着きました。
日記や本を読んでいて気に入ったフレーズ、詩などを1日1ページでメモしています。
アプリだけど紙の本や詩集みたいになって最高です。
課金も買い切りで、しかも少額なのでありがたいです。

もしリクエストができるなら、
・アプリのテーマカラーを増やして欲しい(パステルカラーなど、淡い色が欲しい)
・ページに画像を貼り付けられるようにして欲しい(日記のように使用しているため、画像貼り付けができたら…と毎回思っています)
この2点を、追加課金でも良いので実装していただけると嬉しいです。

DO NOT DOWNLOAD THIS APP!!

They have deleted all my previous notes and information. They just want you to purchase in app ads and they leave you no out to reject. This has become a scam app. I believe these reviews are fake. If you have this app delete it immediately.

Perfect app!

Love the simple and minimalist design, I’ve been using it since 2020. One thing I would truly appreciate is if pictures function could be added! Overall I love the app
