Choose Beam if
Developers and creators with two Apple silicon Macs who want a remote app to behave like a local window instead of a full screen share.
- Uses one remote app without taking over the whole desktop
- Window traffic goes directly between your Macs, not through Beam's servers
- Free plan has no card requirement and no limit on host Macs
Look elsewhere if: People who need to reach Windows or Intel machines or control a whole remote desktop across platforms (Jump Desktop, Parsec).
Choose Kalender Sync if
Freelancers and consultants in Europe who need GDPR-compliant sync across Google, Outlook, iCloud and German mail providers.
- Covers German providers that most sync tools ignore
- Privacy-friendly default shares busy time only
- GDPR DPA included even on the Free plan
Look elsewhere if: Teams wanting AI task scheduling or central admin for many users (Reclaim, Ridian).
