The wedge

The judge
in your pocket.

Fix8 watches the set the way a judge does, frame by frame, fixation by fixation. Calibrated to your body, your set-up, your lockout.

  • Fixation detection — sees the moment the bell is fully fixed overhead, not just the rep peak.
  • Calibrated lockout — set your own line once. Every future set is judged against it.
  • Timed clips, and video burn-in Save and replay your training sessions with precise timing and judge indicators.
    • Fix8 lockout judging — the bell at fixation, with the rep counter, timer and judge line burned into the clip.
    What's inside

    The training tools
    of a serious sport.

    Key pieces, designed for how GS athletes actually work. Nothing borrowed from a generic fitness app — every detail shaped by the rules of the sport.

    Timed set recording

    Film the whole set with the Fix8 timer running. The clip remembers exactly when each rep landed.

    Fixation detection

    On-device vision watches the lockout. Every fixation logged with duration, not just rep peaks.

    Calibrated lockout

    Set your overhead line once, off your own video. Every subsequent set is judged against it.

    Built for athletes first

    Train. Log. Replay.

    Fix8 is shipping to athletes first. The coach dashboard is in progress — we're shaping it with working coaches and rolling it out later in 2026.

    For athletes

    Under the bell, in your pocket.

    • On-device fixation count — no internet needed
    • Replay any set with the timer baked in
    • Create and manage your own timer formats

    Why we're building it

    The training app GS already deserved.

    "Every kettlebell sport athlete I know runs their week off a spreadsheet, films sets on a wedged-up phone, and counts fixations by hand. The sport is precise. The tools weren't. Fix8 is the tool I wanted, and couldn't find."

    FAQ

    Common questions.

    Is Fix8 only for kettlebell sport?
    Yes. We built Fix8 specifically for GS — long cycle, biathlon, snatch etc. The calibration, judging logic and timing blocks all assume the sport. If you lift bells for general strength you can still use the timers, but the product is shaped around competition formats.
    Does the fixation detection work without internet?
    Yes. The on-device model judges every rep locally. Your training data stays on your phone by default.
    What does "calibrated lockout" mean?
    You record a short calibration clip once: a clean fixation with your bell, at your platform, in your stance. Fix8 measures your own lines — then judges every subsequent set against that, not a generic average.
    Is there an Android version?
    Android is in active development and going into closed testing next. Join the waitlist and pick Android as your OS — that's how we'll invite the first round of testers as capacity opens up.
    How do I get access?
    iOS is available free on the App Store. We're still building the waitlist for Android testing and the open release — drop your details and we'll be back in touch when the next intake opens.
    When does the coach dashboard ship?
    After we finish the athlete release. We're shaping the coach side with working coaches now and rolling it out later in 2026. If you coach a squad, tell us about it on the waitlist — early coach slots will come from there.
