Mobile analytics made
for agentic development

// Track an event from your app.

// 1. Add https://github.com/mixpanel/mixpanel-swift as a Swift Package Manager dependency.
//    Undercurrent ingest is wire-compatible with Mixpanel.

// 2. Set up a reusable mechanism for creating events throughout your app.
import Mixpanel

class UsageAnalytics {

  private let tracker: MixpanelInstance

  init(distinctId: String) {
    self.tracker = Mixpanel.initialize(token: "<your-undercurrent-project-token>", trackAutomaticEvents: false,
                                       serverURL: "https://ingest.undercurrent.dev")
    tracker.identify(distinctId: distinctId)
  }

  func event(eventName: String, properties: [String: String]?) {
    tracker.track(event: eventName, properties: properties)
  }
}

// 3. Produce events based on user interactions.
struct MyView: View {

  @EnvironmentObject var usageAnalytics: UsageAnalytics

  var body: some View {
    Button(action: {
      // <Do something>
      usageAnalytics.event(eventName: "tappedButton", properties: ["userFeedback": "This is a useful app!"])
    }) {
      Text("Submit")
    }
  }
