Phone died? Reach your people now →
TRY IT: ASK YOUR TEENAGER FOR YOUR NUMBER

They don’t know your number.

It lives in their phone, not their head. When that phone dies, they lose their way to call you. ZeroPercent lets them reach you from any borrowed phone, no number needed.

Not a tracker. Never will be. NO LOCATION · NO MESSAGES · NO APP ACTIVITY · EVER
HOW IT WORKS

A dead phone stops being an emergency.

ZeroPercent is a family app that lets you reach your people from any borrowed phone when yours is dead, lost or stolen. Borrow any phone, open zeropercentapp.com, and text your people without knowing their numbers. It is free for up to six people and it never tracks location.

1

They borrow any phone

A friend's, a shop assistant's, the staff at the station. ZeroPercent teaches them exactly what to say when they ask.

2

They open zeropercentapp.com

In any browser. Nothing to install, no sign-up for the lender, and nothing stays on their phone afterwards.

3

They reach you

Their people are right there by name, no number needed. They reach you by text, or by a call on Pro, and replies come back on the borrowed phone.

THE PART YOU DO ONCE

On an ordinary Tuesday, not at 1am.

The rescue works because the setup already happened. It takes about two minutes, and then you mostly forget about it.

WHY TEENS KEEP IT INSTALLED

You see enough to relax. They see exactly what you see.

Parental-control apps get deleted. ZeroPercent survives because it's honest: your teen has a "What my family can see" screen showing the exact, complete list, and it's short.

WHAT YOU SEE
✓ Latest battery % with an honest timestamp ✓ Whether ZeroPercent is set up and ready ✓ How many backup contacts they have (the count only)
WHAT YOU NEVER SEE
✕ Where they are ✕ Who their backup contacts are ✕ Messages, browsing, or app activity
Battery readings can arrive late when a phone is in Low Power Mode, so each one shows how old it is.
PRICING

Free keeps everyone safe. Paid lets them hear you.

Free: everyone on your plan can text their people from any borrowed phone and keep three backup contacts each, and the adult(s) who run the plan get a battery heads-up when a phone is running low. Pro: everyone can also call from a borrowed phone, with as many backup contacts as they like. Backup contacts don’t need the app or an account. Only the person who sets up ZeroPercent pays; everyone they invite is included.

GOOD QUESTIONS

Asked before you have to ask.

Does ZeroPercent track my teenager's location?

No. Never. ZeroPercent has no access to location, messages, browsing, or app activity. It isn't a parental-control app, and it never will be.

What can the adult(s) who run our family actually see?

A short, complete list: the latest battery percentage with an honest timestamp, whether ZeroPercent is set up and ready, and how many backup contacts someone has (the count only, never who they are).

What happens when the phone actually dies?

They borrow any phone, open zeropercentapp.com in the browser, answer three things they already know, and reach their backup contacts. Nothing installs, and nothing stays on the borrowed phone afterwards.

What to do if your teenager's phone dies

What if the phone is lost or stolen, not dead?

The same thing works, because ZeroPercent never needs the missing phone. They borrow any phone, open zeropercentapp.com, answer three things they already know, and their backup contacts are there by name. ZeroPercent does not locate, lock or wipe a phone; use Find My or your mobile network for that. What to do if their phone is lost or stolen.

Does the borrowed phone need the app?

No. The ZeroPercent app is for iPhone, but the rescue side works from any phone with a browser: Android, iPhone, anything someone will lend for a minute.

We're on Android. Can we use ZeroPercent?

Yes. The app is iPhone only for now, but on Android you can do everything except the battery heads-up in your browser at zeropercentapp.com/me: set up your own rescue, join a family, or start a family and run it, with nobody needing an iPhone. How it works on Android.

What do I get free?

A real product, not a taster. Free protects your whole family, for good: the family screen, a battery heads-up when a phone is running low, texting for help from any borrowed phone, and three backup contacts each. Backup contacts don’t need the app or an account. Paying adds voice calls and unlimited backup contacts, and only the person who sets up ZeroPercent pays.

How much does ZeroPercent cost?

Nothing. Up to six people are free, including the battery heads-up, and texting for help is always free. Pro adds Global Voice, calling your people from any borrowed phone anywhere in the world: £4.99 a month for two people, £7.99 for up to six, or 30% less paid yearly.

Which countries does it work in?

The UK, the US and Canada today. Your backup contacts need a number in one of those, and the rescue page works from a borrowed phone anywhere. Somewhere else? Vote for your country and the most wanted open next.

Ready before it's ever needed.

Set your family up in 2 minutes, free. The day a phone hits 0%, you'll be glad you did.
