Many iPhone users currently lack a quick way to check when they last unlocked their device. This creates unnecessary repeated unlocking and makes it harder to track phone usage habits. While iOS offers detailed usage data in Screen Time settings, this information isn't readily visible where users need it most - directly on the lock screen.

A Simple Lock Screen Enhancement

One approach could be adding a small, unobtrusive timer to the iPhone's lock screen showing the last unlock time. This could appear near the clock or in the Today View (accessed by swiping right), displaying either exact times ("Last unlocked: 2:15 PM") or relative durations ("2 minutes ago"). The display would be configurable, giving users instant feedback about their recent device usage without needing to open Settings or install third-party apps.

• For productivity-focused users: Quickly confirm if they just checked their phone
• For digital wellbeing tracking: Easy reference for usage patterns
• For users with attention challenges: Visual reminder of recent interactions

Implementation and Integration

This feature could leverage iOS's existing infrastructure for minimal development overhead. A simple MVP might involve:

1. Creating a lock screen widget using existing frameworks
2. Utilizing already-logged unlock event data (no new background processes)
3. Offering basic customization through Settings

Potential refinements could include optional geofencing to automatically hide the display in certain locations, or the ability to toggle between different time display formats.

Comparison With Existing Solutions

Unlike Android implementations buried in settings or third-party apps that require installation and background processes, this approach would offer native iOS integration. It would be more seamless and energy-efficient than alternative solutions while providing quicker access to this specific piece of information than Screen Time offers.

Such a feature could demonstrate thoughtful attention to user experience details while maintaining Apple's design standards. Its unobtrusive nature and optional configurability would let users choose whether and how to incorporate it into their lock screen setup.
