User Reviews

Users appreciate Notepad With Password for its simplicity, ease of use, theme options, and fingerprint authentication, making note-taking convenient and secure. However, multiple users highlight concerns regarding password recovery and reset options, occasional unexpected password prompts, lack of data backup, and inconsistencies with password protection, which affects access and security. The app's storage size is also seen as large by some. Overall, it's a straightforward note app valued for quick notes but needs improvements in password management and backup features.
