Digitalquill Ltd are proud to announce our latest Android app: Smoke Signal. Building on our experience in commercial monitoring solutions, the app, which reminds domestic users to test their smoke alarms is launched on the Google Play Store on #TestItTuesday 3rd July.

Smoke Signal – Smoke and Carbon Monoxide Alarm Testing App

According to, a working smoke alarm cuts your risk of dying in a fire by half. However, In the English Housing Survey in 2014/15, 25% of people questioned said they did not test their smoke alarms at least once a month. In 2016/17, where a fire occurred in a home with smoke alarms that resulted in a casualty, 12% had a missing battery, and 10% had a defective battery.

Free App Reminds you to Test Smoke Alarms

Digitalquill’s Managing Director, Matt Houldsworth says:

“The #TestitTuesday hashtag on Twitter is raising awareness each week of the need to test smoke alarms, but not everyone uses Twitter. Fire safety is one of our company’s passions, and our commercial fire door inspection and monitoring system already make offices, hotels and other commercial buildings a safer place. We wanted to give something back by offering Smoke Signal as a free to use app for domestic use, that helps people remember to test their smoke and carbon monoxide alarms weekly – even if they do not use social media.”

Flexible Reminder Schedule for Smoke and Carbon Monoxide Alarm Tests

Smoke Signal is totally free to download and use, and it does not require users to provide any of their details. The user logs all of their smoke alarms in the app, and it then triggers a reminder to check each smoke alarm’s function on a weekly basis. The user can choose what time and which day of the week to be alerted, and every six months they are reminded to change their alarm batteries. It also tracks the alarms expiry date after which they are no longer effective. The app also supports Carbon Monoxide detectors in the same way.

Why is it important to test smoke alarms?

Smoke alarms are crucial as an early indicator of a fire in the home, but all too often their batteries are not checked, and so the alarm does not sound in the event of a fire. Digitalquill’s free smoke alarm testing app, Smoke Signal, supports the #TestitTuesday campaign by reminding people to test their smoke alarms every week.
