About this app

Sister is the most complete safety app, it is female-led and tailor-made to ensure safety at home or outdoors. Asking for help is discreet and can be done for both prevention and emergency.

With Sister you can:

- Choose your trusted contacts and share your live location with them.
- Follow the safest route, seeing the police stations nearby and the risk zones of your city.
- Activate a deterrent alarm.
- Ask for help to your contacts and, if you want, to the emergency services.
- Register evidence: on SOS mode your telephone records automatically audios and take pictures that are stored on Sister’s cloud.

How does Sister work?

Sister provides security 24/7 to be protected all day long and walk without fear.

#1 Prevention

Use Sister to share your whereabouts with your trusted people so they can walk you home in real time. You can also select the safest route, seeing the nearby police stations and the risk areas, where other users on Sister have asked for help.

# 2 Reaction

If you are in danger, activate SOS with one click and we'll send your live location to your contacts, notifying them that you need their help. Also, we'll display the number of the emergency services for you to call if you want. If something happens, you can always use the evidence that the app registers and stores confidentially in its cloud, never in your phone.

*You can also activate SOS with a shortcut: long press the volume up button.

Sister is not just an app, it is a technological ally in the fight against sexual harassment. Currently, we work with international NGOs to improve the safety of girls and women around the world.

Awful. Unreliable, doesn't work 50% of the time. I now get an 'oops, something went wrong' error on launch with no way of fixing. Have tried to reinstall but get a similarly annoying message that the app can't find my internet connection. I have a paid subscription. Don't bet your personal safety on this app. Very disappointed, I'll be asking for a refund as it's not fit for purpose

I paid money to see risk areas but there's no info. What's the point of that I thought it might cross reference with recent violent crime data or sex offenders to make high risk areas red or something but it doesn't do that. It depends on reports by people. There is no visible way to delete your account once signed up. It wants phone number and email with no way to remove this information later but they make it real easy to add more. This is doing the opposite of making me feel safe and secure.

Hi Naomi! The risk zones maps inform where other users have asked for help so it's recent, useful info, crimes rates would be nice to have and we'll consider adding them, thanks! Premium also comes with unlimited, multiple sessions and SMS alerts. For safety reasons we delete the accounts (so no thief can do it), so send us an email to do it.

I got this app for my daughter to make sure she is safe and always has help if she ever felt threatened or scared walking alone. It's amazing and she uses it every day! Knowing that she can contact the police or me directly If anything was to ever happen really puts my mind at ease and I'm sure hers aswell. Both of us would recommend to all women who are ever worried about walking by themselves.
