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.

free for up to 6 people · no tracking, ever
Not a tracker. Never will be. NO LOCATION · NO MESSAGES · NO APP ACTIVITY · EVER
HOW IT WORKS

A dead phone stops being an emergency.

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 trusted people are right there by name, no number needed. Message or call, 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.

Add the people they'd reachNames, not numbers. Private to whoever added them.
See everyone's batteryWith an honest timestamp, so you know how old the reading is.
Get a nudge before zeroOpt-in, off by default, and never a nag.
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 trusted contacts they have (the count only)
WHAT YOU NEVER SEE
Where they are Who their trusted contacts are Messages, browsing, or app activity
Battery alerts are opt-in and off by default. Stale readings are always labelled "last known", never passed off as current.
PRICING

Free keeps everyone safe. Paid lets them hear you.

Free: everyone on your plan can text their trusted people from any borrowed phone, keep three trusted contacts each, see each other’s battery, and get the alerts. Pro: everyone can also call from a borrowed phone, with as many trusted contacts as they like. Trusted 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 my 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 trusted 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 text or call their trusted people. Nothing installs, and nothing stays on the borrowed phone afterwards.

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.

What do I get free?

A real product, not a taster. Free protects your whole family, for good: the family screen, everyone’s battery, the low-battery alerts, texting for help from any borrowed phone, and three trusted contacts each. Trusted contacts don’t need the app or an account. Paying adds voice calls and unlimited trusted 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 screen and the alerts, and texting for help is always free. Pro adds Global Voice, calling your people from any borrowed phone anywhere in the world: $6.99 a month for two people, $9.99 for up to six, or 30% less paid yearly.

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.
