Align.io

Align.io explicitly states it allows users to 'Record your screen' which directly matches the 'Screen Recording' must-have feature. Although not explicitly stated as 'timestamped comments', the description 'describe your thoughts, and our system translates it into actionable tasks' in the context of video feedback strongly implies a mechanism for contextual feedback, which aligns with the spirit of timestamped comments for actionable tasks. The website is very minimal as it's a beta sign-up page, so further features are not detailed.
