# Getting Started

The Senstream iOS Mobile App focuses on capturing data, while the Charts Web App focuses on displaying data after completing a session.

A Senstream account is required to upload, view and share your session data. Tap “Sign In” or “Sign Up” within the app or at <https://charts.senstream.com> using email/password, Apple, or Google OAuth.

After logging in to your account, make certain you have captured at least one data session using the mobile app to be able to see a session display in the charts web app.&#x20;
