Mainly depends on which platforms you use. If you’re using Bitwarden on Android and/or Linux, then this isn’t a replacement. If you’re on Apple’s iOS/iPadOS/macOS or are on Windows, you can use this. These are also native apps, unlike Bitwarden’s Electron monstrosity on the desktop.

Bitwarden has been lagging in implementing any consumer features for some years now (custom item types has been on the roadmap for six years and is still not done). Except for secure notes in Bitwarden, I don’t think you’d miss anything else in this app. Bitwarden is spending money and focus on the enterprise, just like 1Password has been. For the consumer segment, neither of these are good enough now.
