# Coming off a night shift and not sure you locked the door behind you?

> Shift workers often forget routine actions because tiredness and irregular hours weaken memory and scramble the sense of what day it is. One Loop records each action you confirm, like setting an alarm or locking the door, with a time stamp you can check later. It works offline and keeps everything on your phone.

After twelve hours on your feet, the walk from the car to bed is a blur. You set an alarm for your next shift, or at least you think you did. Your body says it's midnight, the clock says 9 a.m., and your memory isn't sure what happened ten minutes ago.

Nurses, warehouse crews, paramedics, factory workers and anyone else on rotating shifts run into this. Your routine changes every week, so autopilot doesn't line up with the clock. A record you make in the moment fills the gap.

## What gets in the way

- **Fatigue at the worst moment.** The tasks that matter most, like locking up and setting the alarm, happen right when you're most tired. That's when memory is weakest.
- **No fixed routine to lean on.** When you leave at 6 a.m. one week and 6 p.m. the next, the usual cues are gone. It's easy to skip a step or think you did it when it was a different day.
- **Days blur together.** Working four nights in a row makes "did I do that today?" a hard question. Was that this morning or yesterday morning?

## How One Loop helps

- **Times you can trust.** Every confirmation is saved with the date and time. When your sense of time is off, the app isn't.
- **A countdown for the stove or oven.** Cooking after a shift while half asleep? Set a countdown and get one notification to go check.
- **Daily reminders at any hour.** Pick whatever time suits your schedule, even 4 p.m., for a med or vitamin reminder. You can change it when your rotation changes.
- **Works in a basement break room.** No signal needed. One Loop works offline, with no account and no sign-in.

## Loops to start with

- **Alarm set** (Voice): Say the time out loud as you set it, like "alarm set for 5:30." You can play it back instead of opening the clock app again.
- **Front door** (Simple tap): One tap as you get in, before tiredness takes over.
- **Stove off** (Camera): Post-shift cooking is a common time to leave a burner on.
- **Car locked** (Simple tap): Parking lots at 3 a.m. are no place to wonder about this later.
- **Melatonin or meds** (Simple tap): Odd hours make doses easy to lose track of. A daily reminder fits your schedule.

## Questions people ask

### Why am I so forgetful when working night shifts?

Sleep loss and a body clock that's out of sync both affect attention and memory. Routine tasks done while tired are stored weakly, so they're hard to recall later.

### Can I change reminder times when my shift changes?

Yes. Daily reminders can be set to any time and edited whenever you like. You can also turn them off.

### Does One Loop need a signal?

No. It works offline and keeps your loops, photos and recordings on your phone.

### What if I'm not sure I took my medication after a shift?

Don't double up. Check the label or call your pharmacist. A timestamped record of each dose can help you avoid the question next time.
