Family Link on iPhone is pretty meh for usage tracking; use Apple’s Screen Time—it’s built in and surprisingly solid.
- Setup: on your phone go Settings > Family > your kid > Screen Time > Turn On (or on her phone: Settings > Screen Time), and enable Share Across Devices.
- What you get: per‑app daily/weekly usage, categories, pickups, notifications, plus App Limits and Downtime you can manage from your phone.
- Quick peek without setup: Settings > Battery > Last 10 Days shows on‑screen/background time by app.
- Want nicer reports/web filters: Qustodio, Net Nanny, or Bark (need physical access to install a profile + a subscription).
