Life is distracting, tag the things you want to keep in range.

LassoTag and the LassoTag app notify you when an item you have tagged gets out of your reach (up to 50 ft diameter) so you can lasso it back in before it becomes lost!

We are the only Apple approved app that will work with any Bluetooth 4.0 enabled device and we can tag up to seven unique items at one time.

The only thing you’ll lose is the stress and anxiety related to keeping track of all your things.

Everyone loses things … their keys, cameras, computers, iPad, and more. Although your computer may contain valuable information,...

Lasso App

Life is distracting, tag the things you want to keep in range…

The LassoTag app for your Apple iPhone helps you monitor 7 items that easily wander away or get left behind. 

The LassoTag app will be available in the iTunes App store in mid November.  We are previewing our product now on Indiegogo,

Want us to send you a LassoTag alert when the app is available?

Lasso What?

LassoTag possibilities are limited only to your imagination.  Here are a couple suggestions and possible scenarios that we are sure you can relate to

Have you ever left a restaurant and forgot to grab your purse? Wouldn’t it be nice to know that you left it behind before you got to the car?

Do you frequently leave your backpack behind?  Get alerted before you are late for class.

Have you ever had a crazy morning racing to the airport and you have a hard time keeping track of all your stuff - your suitcase, briefcase, and laptop case?  Put a LassoTag on it and get a sense of relief. All items will make it on the plane with you.


Fido has a nice big back yard but occasionally likes to jump the fence and visit the neighbor dog.  Wouldn’t you want to know before he is gone too long?  Put a LassoTag on Fido and you will get an alert before he escapes.
