Async video messaging for people you actually talk to.
Roger is an async video messaging app for staying connected with close friends and family through short videos, photos, and notes. It is not a social network. There are no profiles, no follower counts, no algorithmic feeds, no strangers. Just the people already in your phone.
The name is a nod to the radio acknowledgment — roger that, message received.
- Async video messaging. Start a back and forth video chat with one person or up to five. They watch it when they get to it, and can record a video response in reply.
- Photos with optional voice overlay. Send a photo with a voice note attached.
- Notes. Full-screen text with a color background.
- Video calls. If you and someone else happen to be in the app at the same time, you can jump to a video call. It auto-records and saves to the thread so the conversation has no gaps.
- Emoji and video reactions. React to individual messages with emojis or a video reaction.
- Contact-based. Not in your contacts? Then you won't find them on roger and vice versa. This app does not feature social discovery.
End-to-end encryption is not a feature, it's the architecture.
All content is encrypted on-device before it leaves the sender and decryption happens on the recipient's device after download.
Roger uses a global rolling message window (100 messages by default, adjustable). Nothing accumulates indefinitely. When a message rolls off, it is deleted from local storage. Remote storage only holds encrypted content until all parties have received it.
Video calls are end-to-end encrypted natively.
