In beta on TestFlight

Your Sleeper matchups.
On the Lock Screen.

Sideline puts every league you play in on your iPhone Lock Screen and in the Dynamic Island, and keeps the score moving while the app is closed. Glance, don't open.

Join the beta on TestFlight Free for one league. Pro is $4.99, once.

Type your Sleeper username. That's the setup.

01

Pick your leagues

Sideline reads Sleeper's public API, so there's no password and nothing to connect. Your leagues show up; tick the ones you want on your Lock Screen.

02

Start it, or let it start itself

One tap puts the Live Activity on your Lock Screen. With Pro it appears on its own before your first kickoff and updates all day with the app closed.

03

Glance, don't open

Widgets rotate through your leagues or pin one. Tap a league on the Lock Screen and Sleeper opens. Sideline stays out of the way.

Built to be read in the time it takes to raise your phone.
