PhotoMemo - SNS Style Memo is an unofficial SNS style memo app available on iPhone. This app allows users to create and store personal notes within their device without sharing them with others.

With PhotoMemo, users can create any type of memo and even send images along with their notes. The app also includes a search feature that allows users to easily find their photos by category. Additionally, users have the option to create new user profiles and talk rooms within the app.

The developer, Naohito Muraoka, aims to continuously improve and make corrections to the app. It's important to note that PhotoMemo is primarily a memo app and not intended for sharing or social networking purposes.
