Lost Tracker

The Lost Tracker is inspired by adventure and tested in the real world, daily. The tracker is ideal for long distance events, multi-day races, road trips, and adventure trips.

Event Tracking without all the B.S.

In short, we wanted to track and share our own adventures without all the b.s. We hate carrying around additional gear or managing tracking devices. We needed something with an ultra-long battery life. We wanted it to work when cell reception was spotty. And we sure as hell weren’t going to pay another monthly data plan to use it.

We hate cliches but it’s true: we couldn’t find a thing to do it, so we built it.

The Lost Tracker System

Take the existing tracking systems you know of and put them on a diet. The Lost Tracker system is made up of a lightweight smartphone App and an embeddable web map. It’s easy to use, easy to deploy, and requires no additional hardware. There’s not a lot more to it.

The App

Ultra-efficient and simple to use. The app runs in the background on participants’ devices during the event.

Available on iOS and Android.

The Lost Tracker app is a passive tracking application that uses very little data and very little battery. We designed this to work in areas where cell reception is unpredictable. It intelligently throttles it’s use of data based on available sources so it’s not sucking the life out of your phone. Additionally, since it runs in the background, it doesn’t compromise the experience of participants.


  • Free to download.

  • Ultra-low battery usage.

  • Ultra-low data usage.

  • No additional hardware to manage.

  • No additional data plans to pay for.

It’s so simple to use, I forgot it was running. It ran for like 7 days and didn’t make a dent in my battery life. Is this magic?

Built for Event Organizers

The Lost Tracker is your solution for following participants, coordinating transitions and aid stations, lining up photographers, and finalizing finish line preparations. It has been used in over 15 states and 3 different countries to track multi-sport events, biking trips, road trips, canoeing trips, motorcycle rallies, and walks in parks.

Furthermore, the embeddable map allows you to keep your event’s attention on your website. This provides more exposure for your sponsors and a more holistic experience for site visitors such as participants’ friends and family.


  • Images and Visualizations available for post-event posterity

  • Ability to set checkpoints for

  • Ability for participants to ‘Check-in’ at a specific location

  • Password protected events so you can limit participants

On long distance events, it’s so hard to catch up with teams to get the shot I want. This made it easy to find people out in the Driftless area.
