Mobile app for a smart ring with a concealed panic button

Nimb is a personal security system. It establishes emergency communication with friends and family members, emergency services, or committed people nearby.

The Nimb system comprises a smart ring and a mobile app.

Business challenge

Facilitating in-app emergency mechanics

Nimb founders developed a ring with a concealed panic button. It allows sending out a distress signal and share location in emergency situations: if someone got into an accident, collapsed, or was attacked on the street.

Our task was to develop a mobile application and ensure its uninterrupted Bluetooth connection with the ring. The device served only as a panic button, whereas the app bore all the operation logic behind it.

Here's what features we developed

Trusted list

A user can create their Trusted list by selecting trusted contacts and sending them invitations. Those who accept the invitation are added to the list, and receive notifications in the event of an emergency.

Safety circles

These are the lists of people and services that receive notifications when the panic button is pushed.

Relatives and friends

The first circle is made up of family members and friends. This is the user’s Trusted list. They receive an emergency signal in four ways: an installed app, email, ring vibration, and SMS.

Emergency services

The second circle represents emergency services such as ambulance, the police, and fire departments. When activated, Nimb sends the user location to a special call center. From there, the operator contacts an emergency service and reports the user’s details, such as current location, location history, and medical data.

People of the Nimb mutual aid community

The third circle consists of people from the Nimb mutual aid community. They subscribe to tags, and if one user sends an emergency signal, community members will see it on the map.

A user can have different notification settings for different circles. For example, if the user leaves for another city, they can turn off notifications for the first circle and keep notifications only for the emergency services and people nearby.

Coordinating help

The app tracks user geolocation and creates a coordination chatroom. The chat includes everyone who has responded to the signal and decided to come to the user’s aid.

The people in chat can view the user and each other on the map, and exchange messages to coordinate their actions. They also hear what goes on at the incident location, as the app records the background audio and broadcasts it to the chatroom.

Profile with interests and medical record

Nimb learned that users help people with similar interests more readily, so they created interest tags. Users follow a tag and see when a person from their community needs help.

Users also specify their height, weight, blood type, allergies, and chronic conditions so that an emergency response group can give them proper help. They also detail how to get into their workplace, or home so that an ambulance or firefighters can find the right entrance.

Keeping up with the Nimb ring

We were developing the app while the client's team was still working on the ring. The ring had four versions before the release, and we had to follow each version and adapt the app to the new functionalities on the go. It was quite challenging, but in the end we ensured a reliable connection.

In-app Nimb store

Users can choose the ring color and place an order online in the store within the app.

Results

We developed and launched native apps for iOS and Android platforms from scratch. It helped Nimb raise sufficient Kickstarter investment and receive 3,000 ring pre-orders from 47 countries.
