Sign in with a passkey that lives on your device and unlocks with Face ID or your fingerprint. Nothing to phish, nothing to leak.
Lock Kairn with Face ID, fingerprint or a passcode so your portfolio stays yours on a shared phone.
One tap swaps every amount for dots. Percentages stay visible, so you still see how things are going.
Dark and light
A dark theme for late-night checks and a light theme for bright days, both tuned for numbers you can read at a glance. Drag the handle to compare.
