SIGNL4 is how alerting should feel
Very visual and easy to use - you can customize your experience and I love the simple punch in and punch out. The design makes it fun to use and the fact that it is mainly app based means that you can finally really carry your mobile alerting in your pocket. Love it and can only recommend it...

Super easy and effective!
I use SIGNL4 to receive critical alerts that cannot be missed. It never fails to send alerts and the app is very user friendly! I highly recommend it.
