Made for iPhone + Apple Watch
Never leave your
iPhone behind.
PhoneTether gives you a clear warning on your wrist when your iPhone may have been left behind—and keeps reminding you until you reconnect or acknowledge it.

Simple protection
Turn it on. Wear your Watch. Go.
PhoneTether is designed to be useful without asking you to understand Bluetooth settings or technical status screens.
Walk away
If the private Bluetooth link is lost beyond your grace period, your Watch starts warning you.
Get your attention
Reminders become more insistent and continue until your phone reconnects or you acknowledge the alert.
Hard to miss. Easy to stop.
A warning that does not quietly disappear.
One forgotten phone can mean a ruined evening, a long drive back, or a much bigger problem. PhoneTether starts gently, then escalates its Watch reminders when you remain apart.
- Choose a short grace period before warnings begin.
- Sound and haptic alerts follow your Apple Watch settings.
- Reconnect automatically by returning to your iPhone.
- Acknowledge an alert when leaving the phone was intentional.

Private by design
Your routine is none of our business.
PhoneTether does not create an account, request your location, run advertising, or send app activity to Toyz2k servers. The iPhone and Watch communicate directly using Apple’s system services.

Straight answers.
Does PhoneTether track my location?
No. PhoneTether does not request location permission, record where you go, or calculate your exact distance from the phone.
Does it work if my Watch is silent?
PhoneTether requests sound and haptic alerts. Silent Mode, Focus, and watchOS notification rules can affect what you hear, so haptic alerts should also be enabled in Apple Watch settings.
Will it alert at an exact number of feet?
No. It detects loss of the Bluetooth link, not physical distance. Walls, interference, device state, and Apple’s background behavior can change when an alert arrives.
What do I need?
A compatible Apple Watch paired with an iPhone, with PhoneTether installed on both. The initial release requires iOS 18 or later and watchOS 11 or later.
