New dynamicWatch Business Blog

Although this will remain as my personal blog, I’ve started a new blog at Medium for anything relating to the business and technology of dwMap, my popular route planning and navigation app for Garmin GPS running watches and cycling computers.

From its start as a hobby app to its success as most popular app in the Garmin App Store and the launch of the paid Premium version, it’s a project that has gone far further than I ever expected.  Learning how to leverage communications and marketing channels such as blogging and social media has become an important part of the project, allowing me to learn and explore with real data and a real product.

The unexpected success of dwMap

Back on August 31st I shared that I had created a simple route map app called dwMap for Garmin’s popular line of GPS sports watches.


Since watches like the Garmin Vivoactive do not include the ability to show and follow a route, this seemed to satisfy an unmet need, but at the time I expected that just a few hundred runners and cyclists would find the app useful.  I was surprised and excited to see the number of registered users of the app (and its companion website soon climb pass a few hundred, then a thousand, and now to over 50,000!

Although the Garmin watches and fitness trackers are less well known than the Apple Watch or the Fitbit, they have several advantages, such as long (multiday) battery lives, true built-in GPS capabilities (you can leave your phone at home) and are fully waterproof.  New models such as the Vivoactive HR have heart rate sensors built into the back of them.  The Forerunner 735XT combines this with full multisport (triathlon) capabilities , while the Fenix 3 HR is both stylish and packed with hiking and skiing-specific features.

As time allows since August I have been working on adding features and interacting with an awesome community of users, and I will hopefully soon be ready to release a V2 with a set of really cool features.  I continue to use the app myself almost every day, whether I am just recording my activities (which sync automatically from the app to Garmin Connect and Strava) or using the route map to explore a new area.

Initially this was a hobby project to share with a few like-minded individuals, that morphed into a “Big Magic” creative project that I’ve devoted time and energy to simply for the joy of it, and who knows what might come next?

dwMap Garmin Connect IQ Route Maps

Garmin GPS watch-owning friends, my latest side-project launched today.

It’s a Garmin Connect IQ  app for Garmin Vivoactive, Forerunner 920XT, Fenix 3 and Epix GPS watches that lets you download cycling and running routes that you’ve created using popular tools like MapMyRide and follow them on your watch. No more stopping and pulling out your phone or map as you run, ride or hike on a new route.

iStreamMobile and High Country RawFood

I am excited to share that two new businesses started by good friends that I have been advising have just launched.

iStreamMobile offers branded Internet radio streaming services  with innovative content and revenue models.

High Country RawFood is a Colorado-based startup focusing both on creating high quality raw food products (currently available at farmers markets in Breckenridge and Minturn) and on raw food preparation education via classes and through its wHolyFood blog.

Congratulations and good luck!

3D Scan of Marcus

Had the pleasure of attending the inaugural meeting of the San Francisco Reality Computing Meetup Group on Monday.  I saw some mind-blowing demos from Autodesk and Matterport, such as projects Autodesk took part in to:

  • CT scan and image an Egyptian mummy,
  • Use photogrammetry to scan and share models of the Leakey skull collection at the African Fossils project,
  • Fly an inexpensive quadcopter drone (DJI Phantom and GoPro) to capture a model of one of the gunnery batteries on the Marin Headlands in enough detail to hand off to a planner or architect.

Plus, Hans at Autodesk was kind enough to scan this 3D model of me, using a Structure Sensor camera.

Welcome to Gyrovia

Gyrovia™ is the name I have chosen for my new blog that will bring together my work and play interests into a convenient single repository.

First, a big thanks to Gregg Garcia for suggesting the name “Gyrovia”, which brings together my interests in location, drones, movement and Greek street food.
