An App That You Need
Just N'Case!

A safety companion in your pocket to bring immediate assistance to distressing situations wherever you are, saving those precious seconds of life.

  • Background Voice Monitoring

    The app hears your voice constantly when turned on, allowing quick response in an emergency.

  • Location To Emergency Contacts

    While facing threat or emergency, the app sends your last known location to your chosen contacts via SMS and alerts them via an automated phone call.

  • SOS Alarm

    Activating the SOS also gives off a blaring alarm by unmuting the phone and auto raising the volume beyond software capacity of iOS, to alert surrounding people or to even ward off threats.

  • Safety Phrases

    App allows recognition of dozens of safety phrases that activates the SOS signal for dealing with comprehensive range of threats and emergencies.

App Lifecycle

Following a hybrid Waterfall and Agile process, as the project demanded, our team of experienced app developers and project managers finished the app within 2 months.

  • 01
    STEP
    Initial discovery meeting with the client revealed a few more necessary features to be added like panic-reset button and international call assist. These were then amended in user stories and added to the project epics.

  • 02
    STEP
    We started with the core feature of speech recognition first, deviating from Agile, to ascertain its feasibility and test out a voice demo for long-range and muffled speech amplification.

  • 03
    STEP
    Majority of emergency contact management was achieved using Twilio API as the VoIP gateway. A complete native framework was used so as to fully utilize the native iPhone hardware and libraries.

  • 04
    STEP
    During QA and Beta, we tested a lot of use-cases including effects of phone calls, headphones, CarPlay, pocket/purse microphone access and resolved all the issues occurring for each use case.

Challenges

Background Speech Recognition

The challenge was to recognize voice from a distance and our team used native speech recognition libraries and voice amplification code to better handle speech accuracy.

After Call Microphone Access

Microphone access to app was disabled as soon as a phone call or other apps needed access. We resolved this with active user prompts when app was in a standby state.

Global Calling Using Twilio

The idea of the app being a safety tool while travelling was a primary goal. We used Twilio APIs for enabling global messaging and calling in case of emergencies.
