We create fitness fun.

Have some fun with our apps. Or use our SDK to build your own low-code fitness app or device.

BeatBiker. Feel the Music.

BeatBiker connects your music directly to your smart cycling trainer. The trainer resistance then matches the the intensity of your music. So the music becomes the workout.

BeatBiker can also add music driven workouts to apps like Zwift or RGT if you want to take a break from the canned workouts. Keep racking up the XP while you workout with your favorite playlists and artist’s latest album drops.

Don’t have a cycling trainer? BeatBiker also works with your indoor rower, smart treadmill or heart-rate monitor. Don’t have any equipment at all? Just use follow-the-prompts mode.

The ExerScreen SDK

Want to build your own fitness app or experience? Our ExerScreen SDK is less-code for fitness:

  1. Connect cycling trainers, rowers, treadmills, and heart-rate monitors to your existing web app using our pre-built web, iOS, and Android APIs.

  2. Record and store your users workouts and sync them to training platforms like Strava, TrainingPeaks, SportTracks, FitBit, and RunTracker. (Example: our PainSled app)

  3. Emulate Bluetooth cycling trainers or smart treadmills to connect your app to fitness games and experiences like Zwift or Wahoo RGT. (Example: RowedBiker and PainSled)

  4. Convert your users favorite music and sports entertainment content into deeply connected workout experiences. (Example: BeatBiker and ExerPuck)

  5. Let your users workout together online using our social fitness backend. Anyone can lead or join a workout.

  6. Need some help? We’ve been there done that for fitness apps and are happy to pitch in on your project.

Create Fitness Devices.

Hardware has the word “hard” in it for a reason, but we have decades of experience creating fitness and consumer electronics devices. Hardware, firmware, mechanical, manufacturing test, supply chain, and operations. We’re happy to share your product journey.

Drop us an email us at support@exerscreen.com.

The PainSled App

Where it all began. We wanted an app for indoor rowers that collected ALL the rowing data. And synced to the Concept2 Logbook, Strava, TrainingPeaks, SportTracks, etc. And exported TCX and CSV workout files. It also included our first attempt at cycling emulation, which now lives on in RowedBiker.

Find PainSled on the App Store or Google Play.

The RowedBiker App

The cyclists had all the cool games and training apps like Zwift, TrainerRoad, and RGT. We built RowedBiker so folks with indoor rowers like Concept 2 or WaterRowers could join in the fun and/or pain.

RowedBiker uses the ExerScreen SDK emulation modes to make rowers look like cycling trainers or smart treadmills.

You can find it on the App Store or the Google Play Store.

PuckBiker. Watch Hockey. Get fit.

If you watch NHL hockey as much as we do, it’s now the time of the year when we spend a lot of time on the couch.

Project PuckBiker creates real-time workouts that match the intensity of your team or favorite player while you watch the game.

Tip: Getting trapped in the zone on a penalty kill can hurt.

This one is in closed alpha, email us at support@exerscreen.com if you want to give it a go. We can also send you paper versions of the workouts that don’t need equipment or software.
