Every notification
See and act on alerts from any app, with per-app rules and quiet hours.
Across ecosystems
Your watch and your phone, finally on speaking terms.
Tandem connects an Android watch to an iPhone, or an Apple Watch to an Android phone. Notifications, calls, music and health, with everything private to your own devices.
Plus is $20 a year or $2 a month. First month free.
Private by design
Nearby, your devices talk over Bluetooth. Apart, messages are end-to-end encrypted: our servers can't read them.
Easy on battery
Built to use under 5% a day on each device. See the exact number in the app.
Calls and music
See who's calling and answer or decline. Control music with artwork and volume.
Health that follows you
Steps, heart rate and sleep go into Apple Health or Health Connect. Never into ads.
Set up in 3 minutes
Scan a code, check that six numbers match, done.
Honest about the limits
Talking on an Apple Watch during Android calls isn't possible, and iPhone replies from Android watches work in the EU only. See the full list.
