From weekend rides to a world map in your pocket

Long before his app reached millions of people, Mike Falk was just your friendly neighborhood recreational cyclist with a question that nagged him during his weekend rides: how much climbing was I really doing?

Elevation data accuracy on those early smartphones was spotty at best. As a career application developer, Mike thought he could do better, so he decided to do something about it. In the early 2010s, he taught himself Android development, wrote a simple tool to give more accurate elevation readings using high accuracy data from web services.

“Let’s put a map on the screen… put a dot where you are… have it follow you around,” his thinking went. And he kept building from there: adding search, coordinates, weather, even points of interest as the project grew legs.

He boils it down to two factors that transformed this side gig into an official app known as My Elevation.

One was a design overhaul: "it looked kinda terrible at first, but then I took a look at material design and adopted it into the app," Mike says, and it all fell into place.

And two, he introduced a "low-friction" way for folks to give a review — not intrusive, just a gentle nudge that people appreciated. "Once that occurred… the positive reviews came in, and then it just took off."

Today, the business behind the app has a name that carries a personal nod to an old friend: RDH stands for “Rusty’s Dog House,” honoring Mike’s first golden retriever and a long-gone personal website that once chronicled the pup’s life.

So when he needed a company name years later, RDH stuck; you’ll even spot a dog carrying a phone in the logo these days.

And the mission? Simple and useful in the best of ways: deliver accurate ground elevation in a way that’s also fun to use for those who are curious and love to explore.

Keep the route open, not gated

All the while, Mike wanted the app to be free. His rationale was quite straightforward: “it's hard to get people to pay. Once one person pays even 99 cents, they place much higher expectations on the application," and as an independent Android developer with a full-time day job in tech, he didn't think he could adequately meet every customer’s needs.

That’s why advertising seemed to him the easiest way to make the experience free to all but still make some revenue to cover actual costs and time.

He began monetizing early with AdMob, for the simple reason that it was easy to add in, well-documented, and just plain worked.

Mike didn't need to manage many ad accounts or complicated configurations; he needed to ship. "AdMob was easy," he explained.

Mike has also been selective about where ads appear in the app. There's the app's small banner at the bottom of the screen — "nothing that gets in anyone's way."

He's also avoided interstitials and any aggressive tactics due to the fact that users specifically let him know that they prefer it that way.

Today, AdMob is the revenue engine that keeps it all going. At times, it's "beer money" or “pocket money for bike parts"; recently, it helped to pay for a portion of his daughters' college tuition.

And above all, it pays for the services behind the scenes that keep the app humming (from cloud services to other APIs, for instance), especially when traffic is high.

“Ad revenue is what powers the model from beginning to end: "it's all due to ads. The app is free with ads."”
A steady ascent with room to explore

Over the years, the app has reached a wide, outdoorsy audience that spans across more than a hundred countries, accruing millions of downloads. That’s the kind of reach that only happens when a tool is available and accessible.

And the ad revenue is what powers the model from beginning to end: "it's all due to ads. The app is free with ads," says Mike bluntly. It funds infrastructure, and gives him leeway to make thoughtful, user-oriented choices.

What's next for RDH? Mike would love to explore an iOS version of the app (but maybe once he has the time to work on it in retirement). For now, he’ll keep fine tuning the Android app and experimenting (very carefully), perhaps adding a splash banner and some kind of premium feature set.

But the essence remains the same: accurate elevation plus a free, ad-supported experience that respects people's attention (and their bank accounts).

He'll continue tipping his cap to Rusty though, that loveable canine who loaned his initials to a company that now helps people worldwide understand the lay of the land — literally.

About the Publisher

Mike Falk is the founder behind RDH Software and the creator of its popular app My Elevation for Android. What started as a way to get better ground elevation readings from a phone has now grown into a resource used by explorers everywhere. The name “RDH” is a nod to Rusty, Mike’s first golden retriever. Mike continues to iterate on the app these days, with a promise: you get accurate elevation that’s kept free with the help of an ad-supported model.
