BRZRKR

Build FIGHTNESS™.

BRZRKR is a local-first workout and work-capacity tracker built for conventional, functional, tactical, outdoor, and improvised training. Plan operations on your phone, define the equipment and exercises that matter to you, and log the work wherever it happens—from the gym to the garage, trail, yard, or basement.

Completed sets earn Work Score based on movement volume, load, difficulty, exercise factors, and time. BRZRKR turns that work into a rolling FIGHTNESS™ signal across the last 7, 30, and 90 days, giving you a clear view of demonstrated capacity without pretending it is a medical measurement.

The phone plans the mission; the watch executes it. Reusable templates, live set completion, persistent workout history, and Garmin support keep the system practical when it is time to stop planning and start moving.

Your training data stays on your device unless you choose to export or back it up. No account required. No cloud lock-in.
