About
Built by a lifter who got tired of broken strength tracking.
The Founder Story
I bought a Garmin Fenix because I wanted one device for everything: running, lifting, sleep, HRV. The endurance side was flawless. The strength side was broken.
Garmin Connect’s strength UI had not been meaningfully updated in years. No exercise-level heart rate data. No PR verification. No way to see which exercises spiked you into zone 5. And if your Bluetooth dropped mid-set? Data gone.
I built Rack because I needed it. A native ConnectIQ app that talks directly to the watch over BLE, caches everything in a DataBuffer, and treats the phone as optional. Every rep gets a timestamp, every PR gets biometric proof.
Rack is not trying to replace Garmin Connect. It fills the gap that Garmin left open: serious strength tracking with the sensor data you are already wearing.
Philosophy
Three principles. No compromises.
BLE First
Every feature starts at the Bluetooth layer. If it does not work on the watch, it does not ship. Phone is secondary.
ConnectIQ Native
Rack runs natively on Garmin through ConnectIQ — not a web wrapper, not a notification relay. Real CIQ code on real hardware.
Data Stays on Device
Your workout data lives on your phone and watch. We never harvest it for ads, sell it to third parties, or require cloud accounts to use core features.
What Rack is NOT
- Not a social network. No feeds, no likes, no followers. Your training is yours.
- Not an AI trainer. Rack tracks and verifies. It does not tell you what to do.
- Not a running app. Garmin Connect already handles endurance. Rack is for the weight room.
- Not for Apple Watch. Garmin's sensor stack and battery life are purpose-built for serious training.
- Not for casual users. If you train 3+ days a week with barbells, Rack is for you.
