ApowerREC

Apowersoft Free Online Screen Recorder directly offers screen and webcam recording, which are must-have features. It also provides instant sharing via links and basic editing capabilities like trimming. While it doesn't explicitly mention viewer analytics or emoji reactions, it does offer cloud storage and sharing, which aligns with the core concept of asynchronous video communication. The website also mentions a desktop version with more advanced features, and an 'Apowersoft Unlimited' suite that includes various tools, some of which align with 'other' features like API access and mobile app support (through other Apowersoft products).
