Origin

Garmin watches are built for endurance - running, cycling, swimming. The strength side was left behind. No exercise-level heart rate data. No PR verification. No way to know which lifts pushed into zone 5. And when Bluetooth dropped mid-set, the data was gone.

Every existing app treated the watch as an afterthought - syncing workout logs post-session through the Garmin Connect API. None of them communicated with the watch in real time. The gap was architectural, not cosmetic.

Rack was built from the Bluetooth layer up - a native Connect IQ companion app written in Monkey C, with a BLE communication protocol and iOS companion designed to close that gap permanently.

Commitments

Three promises. No asterisks.

Data ownership is non-negotiable.

No selling, no harvesting, no cloud requirement for core features. Full export at any time. Athlete data belongs to the athlete.

No manufactured urgency.

No fake countdown timers. No "3 people viewing this." The Founder's counter syncs from RevenueCat - not a CSS animation. Trust is earned, not engineered.

Dogfooded daily.

Rack is the primary training tool for the team that builds it. Every friction point has been felt firsthand. Every bug report has a personal stake.

What Rack is not

✕Not a social network. No feeds, no likes, no followers.

✕Not prescriptive AI. Rack proposes. Athletes decide.

✕Not a running app. Garmin Connect handles endurance. Rack is for the weight room.

✕Not for Apple Watch. Garmin's sensor stack and battery life are built for serious training.

Roadmap

IOS

In progress

Body Graph Knowledge Layer

Persistent knowledge graph that captures how each athlete's body responds to training. Qualitative memory, temporal patterns, preference learning.

SERVER

In progress

Proactive AI Coach Agent

Server-side signal detection with push delivery. Plateau, recovery, imbalance alerts. Accept/reject workflow with full audit trail.

WATCH

Planned

Superset & Circuit Mode

Native CIQ support for supersets, circuits, and giant sets. Auto-detecting exercise transitions with seamless timer management.
