Meet Eliud Gilisho, Kenyan Innovator Behind App That Makes Stolen Phones Scream ‘Huyu ni Mwizi’

Eliud Gilisho is a Kenyan innovator whose personal experience with violent crime inspired him to develop a technology solution aimed at combating mobile phone theft.

His innovation is an anti-theft application designed to make stolen phones produce a loud alarm, alerting people nearby and potentially making it difficult for thieves to escape unnoticed.

The idea behind the application was conceived in 2025 following a traumatic experience that changed his perspective on personal security and technology.

Gilisho was walking home one evening when he was attacked by criminals riding on a motorcycle. The assailants were armed with weapons and subjected him to a violent robbery.

During the incident, he was harassed and stabbed before the criminals made away with his mobile phone.

The loss went beyond the financial value of the device. His phone contained important contacts, personal documents and other valuable information that he could no longer access.

The incident left him reflecting on how vulnerable mobile phone users were to theft and how technology could be used to discourage criminals.

Rather than allowing the experience to discourage him, Gilisho turned his frustration into an opportunity to develop a practical solution.

He began working on an anti-theft application that would help users respond when their phones were stolen.

The application is designed to activate a loud alarm that makes the phone announce, ‘Huyu ni Mwizi’, a Swahili phrase meaning ‘This is a thief’.

The idea is to attract attention from members of the public, expose individuals carrying stolen devices and make it harder for criminals to quietly disappear with their victims’ phones.

Gilisho’s innovation highlights how personal challenges can inspire practical technological solutions to everyday problems affecting society.

With mobile phone theft remaining a concern for many Kenyans, his idea demonstrates the potential of locally developed technology in addressing security challenges.

His journey also serves as an example of turning a painful personal experience into an opportunity to create something that could benefit other people.
