What Lark Alert does
Wireless sensors in your coolers and freezers, readings in the cloud, alerts on your iPhone.
Wireless temperature sensors
A sensor in each cooler or freezer measures the temperature where it matters — inside the unit — and reports it wirelessly.
Readings recorded in the cloud
Readings go to the Lark Alert cloud service, so the history of a unit isn't stuck on a device in the back of the kitchen.
A range for every unit
Each unit gets the temperature range you expect it to hold, so a walk-in cooler and a chest freezer are judged on their own terms.
Out-of-range alerts
When a reading falls outside a unit's range, Lark Alert alerts you instead of waiting for someone to notice.
Device-offline alerts
If a sensor stops reporting, you hear about it. Silence isn't treated as good news.
Alerts on iOS
The Lark Alert iOS app puts current readings and alerts on the phone that's already in your pocket.
Why offline alerts matter
A temperature monitor that only reports when things are fine is a monitor you can’t trust. A cooler that’s warming up and a sensor that has gone quiet look identical if nobody is watching for the second case. Lark Alert treats both as conditions worth waking you up for: an out-of-range reading and a device that has stopped checking in.
