Wisp

Wisp is a fast Android nostr client built by Barry Deen. It packages the familiar parts of a social app into one mobile experience: a chronological feed, photos and videos, rooms, live streams, private messages, reactions, and a wallet for sending money as easily as liking a post.

The client is designed for people who are new to nostr. Wisp implements the outbox model, supports dedicated DM relay sets, and uses end-to-end encrypted private messages. Users can join topic rooms, build custom feeds, upload media through Blossom, and move around the network without depending on a single platform account.

Wisp also includes a non-custodial wallet based on the Breez SDK (Spark). New users can receive zaps, send sats to creators, pay friends, and recover their wallet with a seed phrase. The wallet can display balances in USD, and encrypted wallet backups are stored on relays the user controls.

Why fund it?

Nostr needs clients that feel useful before a user understands relays, keys, or Lightning. Wisp hides much of that complexity while keeping the underlying protocol benefits intact: portable identity, user-chosen relays, open-source code, and direct bitcoin payments.

OpenSats supported Wisp in the seventeenth wave of Nostr grants. The grant helps Barry work on Wisp full-time and keeps development focused on onboarding, mobile polish, private messaging, and payments.

What's next?

The submitted roadmap started with the Q2 2026 push to leave beta, ship Normie Mode with USD-denominated wallet balances, publish on Google Play, and launch the web client. The next phase moves Wisp across platforms: Wisp for iOS is planned for development and beta launch through Q3 and Q4, while Dark Wisp explores a more privacy-focused Android fork. Relay-based private communities are planned for Q1 2027.
