## Review summary

OpenKeychain is widely praised for easy, beginner-friendly OpenPGP features, reliable performance, and ad-free use, with strong key management that pairs well with Thunderbird and FairEmail. It’s privacy-focused and open-source. However, several reviews cite stalled maintenance, an aging UI with confusing UX, and gaps in interoperability (signing/signature checks, key import, Outlook compatibility). Occasional cryptographic errors are also reported. Overall it’s a solid privacy tool, but users want active development and a modern, more intuitive interface.

### Pros

- Easy to use and learn, including for elderly users
- Stable and reliable performance; it just works over years
- Strong key management and OpenPGP capabilities (encrypt/decrypt) with good integration with email apps like Thunderbird and FairEmail
- Ad-free and free to use
- Privacy-focused and open-source approach that supports privacy-centric workflows

### Cons

- Maintenance and updates appear stalled or uncertain (not actively maintained)
- Outdated UI with confusing UX and some hidden controls (e.g., encrypt button)
- Interoperability and feature gaps (signing/signature checks, key import limitations, Outlook compatibility)
- Occasional bugs/errors (OpenPGP exceptions, initialization failures)
