Loop users who log a meal in advance can now ask for a reminder to eat. When the meal meets the advance-time threshold, Loop offers Remind Me or Skip Reminder before the bolus screen. Choosing Remind Me schedules a Time Sensitive notification for the meal time once the carb entry is saved.

• Settings → Alert Management → Reminder Prompt defaults to 30 minutes and offers Off, Any Future Time, and thresholds through four hours.
• Pending reminders follow edits to the carb entry and are removed when the entry is deleted. Reminder sounds follow Loop’s mute setting.
• The shared future carb-entry limit increases from one to four hours for manual and remote entries, revisiting Modify maxCarbEntryFutureTime to 4 hours #2125. A meal at the four-hour limit can trigger the prompt.

Implements #2650.

Captured before rebasing on the latest next-dev, using a 45 g demo meal and Any Future Time so the reminder would arrive promptly. iOS groups the new notification with an earlier demo notification.

Validation

• 130 focused tests passed on an iPhone 16 Pro simulator (iOS 18.5). The suites cover the carb-entry prompt, reminder scheduling and cancellation, bolus flow, alert muting, and the four-hour carb boundary.
• Verified delivery of the Time Sensitive notification on the simulator lock screen after saving the demo meal without a bolus.
