Launch HN: Charge Running (YC W21) – Social running app with real-time coaching

75 pointsby mknippenabout 4 years ago
Hi HN,<p>I’m Matthew Knippen, a 10 year iOS dev turned CEO for Charge Running (www.chargerunning.com). We built a mobile app that allows you to run with others from all over the world in real-time, all while being trained by a certified run coach. Think of us as Peloton for running, but way more social. You can learn more about our product here: <a href="http:&#x2F;&#x2F;www.chargerunning.com" rel="nofollow">http:&#x2F;&#x2F;www.chargerunning.com</a><p>I’m a career mobile dev that always liked hacking on things, and worked on over 60 applications ranging from photos, games, and fitness. Over the years, when I come across a problem in my life, I write code to solve it. I built a garage door opener app before it was cool, an electronic Go board, and an app to track different whiskeys I’ve tasted like “Untappd for Spirits.” Charge was born out of a much bigger personal problem:<p>I used to run a fair bit with my friend (and now co-founder) Rory. It was a great way to stay in shape and having someone to talk helped the time go by faster. Unfortunately, when Rory moved across the country for the military, both of us ran significantly less than we did before. I came to the conclusion running by myself… SUCKED! We were chatting about it on the phone one day knowing there had to be a better solution, and that&#x27;s when we thought of Charge. I spent the weekend hacking something together, and on Monday, we tried it out.<p>Our first version of the app was an all white screen where it showed two things, Rory’s distance, and mine. We hopped on a phone, and used the app to have a friendly competition. A programmer vs a Navy Seal is rarely a fair challenge, and he kicked my a$$, but we LOVED it! On the backend, we utilized Firebase’s Realtime database for data, and a group phone call to manage audio. (Most of this has since been upgraded)<p>As any developer would want to do, we kept building on it, showing things like current pace, cadence, and more. A few friends wanted to join us, so we built support for multiple users, and listened to music while we ran. It was at this time that someone joined us that was a friend of a friend, and said “Now that I know I can run with this, I never want to run without it.”<p>So, we decided to turn our ugly hacked together app into an official product. When talking to our users, we found out that they wanted four things during their runs: 1. Motivation - The hardest part about going for a run is committing to do it and getting those shoes on 2. A social experience - Every other running app focuses on social after the run, not the ability to run with others in real-time. 3. Education - Most beginner runners just start running. After hearing Rory talk with them, they learned proper form and how to improve without getting injured. 4. Music - When asked what a big pain point was, users said they needed to put more work into their playlist than they spent running!<p>We took that information, and made a small pivot into dedicated coached classes, where a certified trainer would guide you through a specific type of workout. Each workout was effort-based, meaning whether you’re a complete beginner, or have run 25 marathons, you could join any class and fit right in.<p>We hired coaches (finding them by doing a bit of web scraping ) and built an audio solution with professional DJ software, allowing the coaches to change the beat of the music and auto-blend them together.<p>Rory and our other co-founder Julie (my sister), would host a few classes a day. I quit my job as an iOS contractor for a big company to focus on a start-up full time, at the same time my wife was 8 months pregnant with our first child. (I have the world’s most supportive wife!)<p>We launched, and we’re instantly overwhelmed. Apple featured us on “New Apps We Love”. MacWorld called us the “App of the Week”. We got 25K downloads, but we&#x27;re still in a very early beta. We had no on-boarding. No app store video. Calling it a website would be an exaggeration. No one knew what we did, or how it worked, and we churned 99% of the users within the first week.<p>However, the ones that stayed lit a fire inside of us that we never knew we had. We talked to them constantly, and they defined our product roadmap. Since then, we’ve had users run over 350,000 miles in live classes, hosted a wedding day ceremony for them, and have seen people become best friends who live halfway across the world from each other. That being said, we really want to learn more, and keep iterating. We would love to hear the community&#x27;s feedback and answer any questions.

I used to be a marathoner, having logged over 10 thousand and some kilometers across various fitness apps. I&#x27;d led a few clinics and very much enjoy the running world. The running community sorely needs connectivity solutions like this imo. Especially with Covid, most communities have seen local running groups halt and essentially disperse. Strava is still strong however, and Zwift running is the closest thing I seem to use for building connections live with other runners. Something is still needed to make the experience more personable though in this space. I wish you and your team the very best of luck.

Congrats on the launch.<p>Because it is kind of hidden, I am pasting the pricing from the FAQ<p>A one-month subscription is $29.99 and an annual subscription is $239.99&#x2F;year ($20&#x2F;month). Both options give you unlimited access to every Charge Running class, as well as our weekly “Club Races”.

Why did you already build an Android app? You now have to maintain it as you iterate the product. Did you reach some growth milestone and decide to expand platforms in order to maintain growth? Or did you determine that the p2p nature of your app requires maximal network potential in order to have any traction?<p>Congrats on your progress. This is a difficult and risky path you’ve undertaken! Having used RockMyRun early on, and the new Nike coaching, I definitely appreciate the coaching and am curious how real-time will help (yay accountability) or hinder (ugh, scheduling) me getting my runs in.

Matthew! I&#x27;m a front-end engineer at Twitter and an avid triathlete. Seeing this post and the progress you have made gave me overwhelming motivation. I want to help out, I don&#x27;t even know how but I don&#x27;t want to miss the opportunity to be apart of something this awesome.

Really cool looking product. The group that I run with in Los Angeles did weekly runs on Saturday mornings pre-COVID, but since the pandemic has transitioned to remote runs where everyone dials into an audio call and runs separately. It&#x27;s not a great experience. Your app sounds like it&#x27;d be a big improvement over what we&#x27;re currently doing.<p>The one piece of feedback I&#x27;d give is that it&#x27;s incredibly difficult to find pricing info on your site. I&#x27;m sure this is intentional, and maybe you want people to just sign up for a free trial and then learn how much it actually costs later, but at least for me it&#x27;s a huge turnoff when any product does this.

Hi - very cool idea! Will probably try it out. Apologize if this is on the site (could not find it) but do you plan to offer any features to &quot;meet&quot; local runners in person? I am always trying new run clubs, and some have stuck and some have not, but I would absolutely LOVE a way to meet local runners that run similar terrain&#x2F;fitness levels as me. Thanks!

This look like something that I would have used when I started running.<p>Most running injuries happen because of overtraining, heel striding, wrong shoes, rigid posture, stride length, bad upper body form and dynamics<p>Would any of these being taken into account? Considering the sensor data is from the phone I guess not.<p>It would be interesting to see a video of app in action as well as how the trainers view and give feedback.

Very nice, congratulations on your launch! As a lifelong runner I go through phases where I want to train for a specific race, and phases where I just want to go out and enjoy the experience without worrying about speed or distance.<p>This app seems to address a need somewhere in the middle...you want metrics, accountability, and ostensibly, to get better at running. But you aren&#x27;t training for a specific distance, and you aren&#x27;t just wanting to get out for a casual jog.<p>Basically, I really want to try this out (and I will!), but I don&#x27;t see myself as a long-time user of it. Unless the community aspect really does something for me that I&#x27;m not anticipating.

I thought I’d take a look and stopped at step 1 (or step 2) of the signup flow. I’m curious why the signup page on the website has a sign up with Facebook option but doesn’t have a signup with Google or signup with Apple option. I thought there would be parity because of Apple’s App Store rules on this.<p>FWIW, I’m not the target customer for this service due to the high pricing and the fact that I’m not a runner.

Hey all! I&#x27;m the co-founder that Matthew was referring to above. I&#x27;ve recently made my exit from the military after 12.5 years to pursue this crazy adventure! If you have any questions about the coaching or class structure, let us know!

How did you build the iOS app? UIKit? Objective-C++? Swift? React Native? SwiftUI? Flutter?<p>a lot of options these days
