Zappy

Zappy is a free screenshot and recording software for macOS that allows users to quickly capture, annotate, and record their screens. It supports including audio and a selfie view in recordings and offers cloud hosting for paid Zapier accounts, facilitating easy sharing with teammates.

Zappy, a product by Zapier, directly offers screen and camera recording capabilities, which are core to the Loom concept. It also provides instant sharing of these recordings via URL and basic editing features like annotations. While it doesn't explicitly mention viewer analytics or timestamped comments, its primary function aligns very closely with the must-have features of asynchronous video communication. The website also mentions a mobile app, which is an 'other' feature.
