Your keys, anywhere.
The KeepKey companion app lets you monitor your portfolio and approve transactions from anywhere — while your private keys stay locked on the hardware device.
Mobile visibility.
Hardware control.
Everything the app does, your hardware device approves. You can see everything. Nothing moves without your KeepKey.
Portfolio at a glance
See your full balance across every chain in one view — BTC, ETH, Cosmos, and more. Always current, never custodial.
Approve transactions
Receive signing requests from KeepKey Vault. Review the details on your phone, then confirm physically on the hardware device.
Watch-only mode
Monitor any address without connecting hardware. Track holdings, incoming transfers, and historical activity read-only.
Open source
Every line of the mobile app is publicly auditable on GitHub. No hidden telemetry. No vendor lock-in.
Clean. Focused. Secure.
Self-custody in your pocket.
Monitor balances and stay connected to your portfolio from anywhere. Your keys remain on the device. Always.
