Compatible With Any Smart Device

LISNR is a simple and powerful digital signage solution – with just a speaker, advertisers drastically increase audience size, engagement rates and ROI.

Play Silently or With Audio, it’s Your Choice

Smart Tones are inaudible to the human ear and are safe for pets and children. They can be played over other audio or deployed silently.

Battery Efficiency

LISNR is incredibly efficient in CPU/battery usage when compared to other data transmission technologies.  All decoding and encoding happens locally and efficiently ensuring light CPU usage. No server calls necessary.  Audio recording not needed to decode.


LISNR is 99.8% effective of successfully registering our SmartTone on any mobile device regardless of environment, crowd, additional noise or even if the device’s microphone is muffled as if it’s in a pocket or purse.


With LISNR, the sky is truly the limit in terms of who you reach, when you reach them and where. The technology is flexible enough to work in most environments with a consistently high coverage.

Low Cost

Implementing LISNR does not require new hardware or mandatory server calls. We have a simple pricing plan that is pennies compared to other technology providers.
