You can install the Smash Your Fitness app on a shared device, but each person should create and use their own account. Here’s why:
Your own profile: Every player can choose a unique display name and customize their in-game identity.
Personal leaderboards: Your scores and rankings are tied to your account, so you can see exactly how you compare against others.
Achievements and challenges (coming soon): Progress and rewards will be saved to your individual profile, not mixed with someone else’s.
Friends and community connections: Your friend list, social play, and upcoming community features all stay personal to you.
If everyone in a household shared a single account, it would mix up leaderboards, progress, and stats — which takes away the fun of seeing your own results. That’s why we recommend each person creates their own login.
Switching users on a shared device is easy:
Go to your in-game profile.
Tap the Exit button in the bottom-right corner.
Log back in with your own account credentials.
✅ Bottom Line
You can share the app on one device, but for the best experience, each player should have their own Smash Your Fitness account. That way, everyone gets a profile, stats, achievements, and friends list that reflects their play.
