CommandCenter

Your own devices, managed as one fleet.

One device is the Commander and issues orders. The others are Nodes — they report status and carry those orders out. No accounts, no trackers, and orders are signed on the device that sends them.

iOS 27 and later • iOS Only • iPhone and iPad • no public release yet

📊

Fleet Status

Battery, charging state, storage, thermal state, uptime and lockdown state for every device you own, in one view.

✍️

Signed Orders

Every order is signed on the sending device and verified on the receiving one. The relay server holds no private key and cannot forge an order.

📶

Direct On Local Wi-Fi

Devices on the same network talk directly over MultipeerConnectivity. That traffic is encrypted and never reaches our servers.

🔑

No Accounts At All

No email, name or password anywhere. Devices identify with a keypair generated on the device, and the private key never leaves the Keychain.
