How to add a couple distance widget on iPhone
The short answer: install a couples app that supports distance widgets (this guide uses Nestlight), pair with your partner, turn on location sharing on both phones, then add the Distance widget from the lock screen's Customize menu or the home screen's widget gallery. Total setup time is about two minutes. Here's each step, plus how the tracking actually works and what your partner can and can't see.
What a distance widget actually is
A distance widget shows one number — how far apart you and your partner are right now — on your lock screen or home screen, updating in the background without opening any app. It became a TikTok-famous staple of long-distance relationships because it turns an abstract ache ("they're so far away") into something concrete you can watch change, especially on travel days.
Step 1 — Install and pair
Both partners install Nestlight. One of you starts pairing and gets a short code; the other types it in. There's no account or password — pairing is the whole setup, and it takes about thirty seconds.
Step 2 — Turn on location sharing (both of you)
In Nestlight's Settings, each partner turns on location sharing. This is the step people most often miss: distance needs both positions to exist. If only one of you shares, there's nothing to measure — and Nestlight will tell you specifically whose side is missing rather than leaving you guessing.
When iOS asks for location permission, "While Using the App" with Precise Location off is enough for the ambient distance — Nestlight computes distance from coarse positions on purpose.
Step 3 — Add the widget to your lock screen
- Long-press your lock screen, then tap Customize.
- Tap Lock Screen, then tap the widget area under the clock.
- Find Nestlight in the list and choose the Distance widget.
- Tap Done. The distance appears within a few minutes of both phones reporting a position.
Step 3b — Or the home screen
- Long-press any empty spot on your home screen.
- Tap the + button (top-left), search Nestlight.
- Swipe to the Distance widget, pick a size, tap Add Widget.
How the distance is computed (and what's private)
Each phone occasionally reports a coarse position using iOS's significant-location-change monitoring — a low-power mechanism that wakes up on meaningful movement rather than running GPS continuously. The server computes the straight-line (great-circle) distance between the two most recent positions and sends that single number back to both phones. Three privacy facts worth knowing:
- Neither partner ever sees the other's position on a map — only the distance.
- Positions older than 30 minutes don't count; a stale phone means "no distance" rather than a misleading number.
- Turning sharing off deletes your last known position immediately — there's no lingering "last seen" location.
Troubleshooting
The widget says location sharing is needed
One of you has sharing off. Nestlight's Distance card says whose — if yours is on, it's waiting on your partner, and vice versa.
The number seems stuck
Significant-location updates fire on movement, not on a timer — if neither of you has moved meaningfully, the number staying put is correct. Opening the app or pulling to refresh forces a fresh sync.
Worried about battery?
Ambient distance uses the same low-power mechanism as iOS's own location-based reminders. Continuous GPS only runs during an explicit On My Way trip, which you start and stop yourself — that's the feature where you watch the miles tick down live on both lock screens as one of you travels.
FAQ
Why does my couple distance widget say location sharing is off?
Distance needs both partners sharing. If yours is on and the widget still shows nothing, your partner's sharing is off or their phone hasn't reported a recent position — Nestlight says specifically whose side is missing.
Does a distance widget drain iPhone battery?
Not meaningfully, if the app uses significant-location-change monitoring instead of continuous GPS. Nestlight only tracks continuously during an explicit On My Way trip you start yourself.
Can my partner see where I am on a map?
In Nestlight, no. Only the computed distance is ever shown — coordinates are never displayed to either partner, and turning sharing off deletes your last position immediately.
