Sweepline1.1.6 - App Store

Sweepline is a gesture-based dispatch tool for people, spaces, and systems.

Connect to a server you run at home - or one shared by friends or family - then send signal events with directional sweeps or taps. These simple gesture can acknowledge a request, unlock a workflow, hand off responsibility, or trigger a physical system connected to the saved endpoint.

Sweepline is intentionally small - like a Unix utility for your fingers.

There is no feed, profile system, or social network. The app enables team communication, but does not offer direct messages or require logging into a centralized service. Sweepline does its best remembering ed25519 private keys, speaking http, and getting out of the way.

Endpoint servers (anyone can make these) define their own meaning:

. a swipe might open a door
. dispense candy from a gumball machine
. turn on the lights
. acknowledge a request
. dispatch assistance
. mark a work zone active
. start workflows in systems you already use

Messages are signed by default using per-service cryptographic keys so endpoint operators can verify where events came from. If you're developing your own service, you can ignore these signatures while prototyping and later lock it down by recognizing signatures from trusted devices only. This is how you make sure only you or people you authorize are allowed to operate your service.

Sweepline works well with:

. self-hosted servers
. Raspberry Pi projects
. volunteer shift tracking and informal help requests
. pickup sports availability and score tracking
. formal or informal clock-in/clock-out
. maker-space infrastructure
. studio and workshop lighting and controls
. interactive art installations

The protocol is intentionally small and open.
The goal is deliberate, low-friction signaling across independent systems.

Sweepline carries the gesture.
Endpoints make the move.

Version History • An endpoint that responds with a redirect now opens the redirected page (this was previously an error) 1.1.6 Aug 26 Improve presentation of resizable windows on iPad and macOS. 1.1.5 Aug 8 Add quicker access to an endpoint's service key from Settings (ⓘ): long press an endpoint > Show Service Key. 1.1.4 Jul 6 Browser tabs in the in-app browser can now stack, improving multitasking.
@handle endpoints are now presented more naturally, making it easier to work with profiles and services that use handle-based identities. 1.1.3 Jun 23 The globe button is no longer available when a Settings password is set and Allow Endpoint Switching is turned off. 1.1.2 Jun 15 Fixes positioning of Globe button in relation to the Dynamic Island. 1.1.1 Jun 9 Adds support for tap and up/down gesture lanes when connected to Sweepline 1.1 endpoints, enabling more natural interactions for light switches and relays. 1.1 Jun 9 • Faster access to service keys: Tap the Globe > Choose an Endpoint > Key icon. 1.0.3 May 28 • Double tap any endpoint on the 'Choose an Endpoint' or Settings sheet to show its QR code 1.0.2 May 27 New options:
