The best personal safety apps, compared

What a personal safety app actually does

"Personal safety app" covers three very different jobs, and most disappointment comes from picking the wrong one:

1. Reach emergency services fast. Your phone already does this for free: Emergency SOS on iPhone and Android. Some apps add a monitored call center that contacts police for you.
2. Let people you trust know where you are and that you're okay. A circle that sees you arrive home, a check-in, an SOS that reaches them in seconds.
3. Record evidence. Audio and video from the moment you raise an alarm, sent to your contacts.

Pick by the job. Many people need the second one most of the time and the first one rarely, which is why a circle app plus the phone's built-in SOS covers most real situations. We read every vendor's own App Store listing or support page on 7 November 2026; facts below are dated and linked. Prices are not listed here; check each store page.

The apps at a glance

As of 7 November 2026, per each vendor's own App Store listing or support page (linked in each section). "Not stated" means the vendor page doesn't say.

1. Warden — best overall for a trusted circle on iPhone and Android (top pick)

Warden is a location-sharing app where both people choose to share: partners, friends, family and roommates see each other on one private map, get a note when someone gets home, and can pause anytime. For personal safety, it covers the job you need most evenings: the people who'd come and get you know where you are, and you can reach them all at once.

What it does for your safety:

• Arrival and departure alerts. Add places (home, a friend's flat, the gym). When you arrive or leave, your circle gets a note, so "text me when you're home" happens on its own.
• SOS in two seconds. Hold the SOS button for two seconds and everyone in your circles gets an alert with your current or last known position, even if your continuous sharing is paused.
• "Hasn't moved" alert. If you're sharing and stay in one spot for a long time outside your circle's places during the day, the circle is alerted. It's a nudge to check on you, not a diagnosis.
• Locate now. Anyone in the circle can ask for a fresh position when they need one.
• Battery level of everyone sharing, with low-battery alerts, so a dead phone isn't mistaken for an emergency.
• Quick messages: "On my way", "Got home safe" in one tap.

Built on consent. Sharing is off by default and only you can switch it on, on your own phone, for each circle. You always see who can see you; the circle is told who joins and leaves. Pause anytime and your circle sees "Paused", not a fake location. No hidden mode, no microphone access. Your data is stored in the EU, with no ads, no third-party trackers and no data selling. History is kept 30 days.

Setup in five minutes:

1. Install Warden and start a circle.
2. Send the invite code to the people you trust; they enter it on their own phone and you approve each request.
3. Everyone reads what the circle will see and switches sharing on themselves.
4. Add your places and show everyone where the SOS button is.

2. Built in: iPhone Emergency SOS and Check In

Every iPhone can call emergency services with a button press and text your emergency contacts with your location afterwards: hold the side button and a volume button, or press the side button five times with Call with 5 Presses on (Apple). Set up contacts first: emergency contacts on iPhone.

For a single walk or a first date, Check In in Messages tells one friend when you arrive and shares your location, battery and signal if you don't (Apple). Both people need iOS 17 or later, so it doesn't reach Android. Full how-to: Check In on iPhone.

3. Built in: Google Personal Safety app (Android)

Google's Personal Safety app shows as Safety in your app list and is available on some Android devices. Per Google's help page:

• Emergency SOS (Android 12+): press the power button five times or more to call emergency services, share your location with emergency contacts and record video.
• Emergency sharing: your contacts see your real-time location and battery; it ends after 24 hours.
• Safety Check: a timer up to 24 hours; if you don't answer with I'm OK within 60 seconds of the check-in, emergency sharing starts.
• Crisis alerts and car crash detection.

This is the answer to "google personal safety app" and "google safety app": it's free on supported phones and the best starting point on Android. Samsung phones have their own Safety and emergency menu with Emergency SOS and emergency sharing (Samsung).

4. Noonlight — best for a dispatcher who sends police

Noonlight's App Store listing describes a hold-and-release button: press and hold when you feel uneasy, release and enter your 4-digit PIN when you're safe. If you release without the PIN, it says your local police are notified of your location. It lists certified dispatchers on call 24/7/365, texting with them if you can't talk, and crash response. It requires iOS 15.0 or later and is free to download on the US App Store; check the listing for paid features.

Choose it if you want a professional to raise the alarm with police. It isn't built around a circle of friends seeing each other day to day.

5. bSafe — best for live streaming and recording to guardians

bSafe's App Store listing lists "guardians" you invite (as many as you want), Follow Me live GPS so guardians can follow you home and get a message when you arrive, an SOS that starts live streaming plus automatic audio and video recording, voice activation and a fake call. Requires iOS 15.0 or later; free to download.

Choose it if recording what happens matters to you. Warden deliberately has no microphone access and no recording.

6. Hollie Guard — best for shake-to-alert in the UK

Hollie Guard, from the Hollie Gazzard Trust, lets you shake the phone or tap the screen to raise an alert that shares your location and records audio and video for your emergency contacts. It lists a motion sensor for trips and falls, meeting and journey triggers, and Hollie Guard Extra, a professional monitoring service that notifies emergency services for you. UK App Store; requires iOS 14.0 or later; free to download.

7. Life360 — best for families who want driving features

Life360's US App Store listing says location is shared with other Circle members, offers place alerts, and describes SOS Alerts that send a silent alert with your precise location to friends, family members, emergency contacts and responders. It lists crash detection on Silver, and emergency dispatch with live agent support on Gold. Free to download with paid memberships; requires iOS 18.0 or later. More in Life360 alternatives.

Women's safety apps

Many people searching for a "women safety app" want the same three things: someone they trust knows they got home, a fast way to raise the alarm, and no app that someone else can control. Warden covers the first two for a circle of your choosing and is built so nobody can switch your sharing on for you. If you want recording, bSafe and Hollie Guard do that; if you want a dispatcher, Noonlight. For your walk home specifically, see safe walk home apps; for students, campus safety apps.

Personal safety apps on Android

On Android, start with Google's Safety app (or Samsung's Safety and emergency settings) for the emergency call. For a circle that includes iPhone users, Warden runs on Android 8.0 or later in the same circle as iPhones, so a group of friends with mixed phones sees each other the same way. Apple's Check In and Find My don't reach Android.

Troubleshooting: when a safety app lets you down

Alerts arrive late or the location is stale. Background location must be allowed: on iPhone, Settings > the app > Location > Always; on Android, Settings > Apps > the app > Permissions > Location > Allow all the time. Low Power Mode and Battery Saver can slow updates; see why location isn't updating.

The SOS didn't reach anyone. Phone SOS needs contacts set up beforehand and, on Samsung, an active SIM. App SOS needs a data connection and people who actually joined your circle.

My friend can't see me. In circle apps, both people must join and switch sharing on. In Warden, check you're not paused and that sharing is on for that circle.

Where Warden doesn't fit

Warden is not an emergency-services app: SOS reaches your circle, never the police or 911, and there's no crash, fall or medical detection, no call center and no recording. It also has no free version (invitees join free on the circle owner's plan). If you need a dispatcher, use Noonlight or your phone's Emergency SOS alongside it.
