We started Korvi because we believed strength training deserved better technology. Not another rep counter on your wrist, but real, full-body motion tracking that understands how you move and helps you train smarter. April was one of our busiest months yet, and we want to share what’s been happening behind the scenes.
The Korvi App Is Live
The biggest milestone this month: the Korvi app is now available on both the App Store and in private beta on Android.
We’ve been building this for a long time, so seeing it go live felt like a genuine turning point. The app is a fully free AI-powered workout tracker that generates personalised training plans, helps you log your workouts, and lets you see what your friends are lifting via our social workout feed. There’s also a body map that estimates muscle fatigue based on your recent training volume. We hope this is handy for figuring out what to hit next.
Right now, the app works as a standalone strength training tool. You don’t need our sensors to use it. We built it this way deliberately: we wanted something that was genuinely useful on its own, not just a companion app waiting for hardware yet to arrive.
Most fitness apps lock their best features behind a paywall after your first session. Not Korvi. Korvi is completely free, no catches. If you download it now during the beta, you’re part of our community from the ground up.
We’re actively squashing bugs and rolling out improvements based on early tester feedback, so if you notice something off, it’ll probably be fixed before you check again. If you have feedback, please email us on support@korvi.fit.
Pushing the Limits of Wireless Sensor Technology
If you’ve read our How It Works page, you’ll know Korvi isn’t just an app. We’re developing a set of wearable IMU sensors designed to track your movement during strength training exercises. Five sensors, placed conveniently around your body, capture motion data at high frequency.
The hard part? Getting that data from your body to your phone reliably in a busy gym.
April was largely defined by this challenge. We started this month testing our custom wireless dongle in a commercial gym environment and quickly discovered that wireless isn’t an easy problem to solve. Our dongle approach uses a different radio protocol, which performed significantly better, but revealed a new problem: body blocking. The orientation of your phone relative to your body can cause entire sensors to drop out.
By the end of the month, we’d moved to a new wireless architecture altogether. Instead of relying on a single receiver, we’re building towards multiple receiving points, spatial diversity, so there’s always a clear path for the signal regardless of how you’re positioned. We’re also exploring whether our sensors can relay data to each other, effectively creating a mesh network on your body.
This is genuinely hard engineering. Nobody in the consumer fitness wearable space has nailed fully wireless, high-frequency, multi-sensor streaming during real gym use. We’re trying to do it with sensors small enough to slip into a compression sleeve. It’s a mountain to climb, but we’re making real progress.
Building the Korvi Community
We spent a good chunk of April defining who we’re building this for. Using audience research data, we’ve mapped out our core user base. We identified five customer personas, from the Tech Pioneer who wants the latest gear to the Comeback Athlete rebuilding after injury, and used these to shape our messaging and channel strategy.
Reddit is where our audience lives, so that’s where we’ve been focusing community efforts. We’re active across fitness and wearable technology subreddits, and it’s been encouraging to see the engagement grow organically. We’ve also set up a Discord server for anyone who wants to follow the build more closely or be in direct contact with the founders.
Our website has had a significant overhaul too. The How It Works section now walks through the hardware, AI, and app in detail. We’ve tried to be transparent about what’s working today and what’s still on the roadmap. If you’re the type of person who wants to understand what’s under the hood before you download something, that page is for you.
What’s Next
May is about three things:
- Getting the wireless right. We’re running experiments with our new architecture to find the limits of what’s possible without wires. Once we can reliably capture high-quality motion data in a real gym, everything else accelerates.
- Feeding our AI. With the database infrastructure taking shape, we’ll start building structured datasets from real gym sessions. This is what allows us to train and iterate on our models at pace.
- Growing the beta. The app is live and free. We want as many people using it as possible, as every bit of feedback makes it better. If you’re into strength training and want to be part of something from the start, download Korvi and let us know what you think.
We’re a small team of four and we’re building this because we genuinely believe it should exist. Thanks for following along.
