There’s a frustrating gap in iOS device management: Apple gives you Finder (barely functional) or iCloud (vendor lock-in). The alternative is iMazing at $50/year.

Phosphor fills that gap for free:

  • Full local backups with scheduling and Wi-Fi support
  • iMessage, SMS, WhatsApp conversation browsing and export
  • Camera Roll access without full restore
  • File transfer, app management, battery diagnostics
  • Contacts, calendar, notes, health data, call logs
  • Export formats: CSV, HTML (styled like native iMessage), JSON, vCard, ICS

Why open source matters here: device management tools have deep system access. You should be able to audit what they do. Phosphor has zero telemetry, zero network calls, and runs entirely locally.

Built in SwiftUI with zero external Swift dependencies. Uses pymobiledevice3 for iOS 17-26+.
