## What is Sidekick?

Team up with one friend, hit your own step, workout or sleep goals, and win the Duo Trophy together.
Sidekick turns your smartwatch, Oura Ring, WHOOP, Garmin, Ultrahuman or Fitbit into friendly two-person challenges.
No rankings, no pressure. Just you, your buddy, and a shared win.

CHALLENGES THAT LIFT YOU BOTH UP
Pick a step challenge, a workout-days challenge or a sleep consistency challenge. Each of you sets a personal daily goal. When you both hit yours, you both win. It is accountability that feels like teamwork.

WORKS WITH THE WEARABLE YOU ALREADY HAVE
Sidekick reads from Apple Health, so it works with smartwatches, Oura Ring, WHOOP, Garmin, Ultrahuman, Fitbit and any device that syncs to Apple Health. It even detects your wearable automatically, so setup takes seconds.

YOUR DAY AT A GLANCE
The Today dashboard shows your steps ring, daily streak and a week streak strip, plus tiles for workouts, sleep and active energy. One look tells you exactly where you stand.

SYNC CHECK: NO MORE MISSING DATA
Wearable stopped syncing? Sync Check spots when data stops flowing and walks you through the exact fix, step by step. If your device goes quiet, Sidekick sends a gentle reminder so your streak stays safe.

CHEERS, NUDGES AND REMATCHES
Send a cheer when your partner crushes their goal, or a friendly nudge when they need a push. Invite friends with a link or QR code, and rematch past challenges anytime.

TROPHIES WORTH CHASING
Earn 3D trophies and milestones, including the Duo Trophy, the Sleep Streak trophy, and step and workout milestones. Every win is one you celebrate together.

PRIVATE BY DESIGN
Only your challenge progress is shared with your friend. Your raw Health data stays on your iPhone.
