About

RoxSplit

Hyrox is the same race every time: 8 runs, 8 stations, and the roxzone transitions in between. RoxSplit is the one tool built to time exactly that. Open it at the start line in two seconds, tap once per segment, and see where every second goes. No login. No training plan. No subscription. Just a split-and-pacing stopwatch that already knows the Hyrox sequence, so you stop fighting a generic timer and start pacing the race. WHY ROXSPLIT • Launches instantly, works offline, never asks you to sign in. The friction the coach apps add on race morning, gone. • Knows the structure. One tap moves you run to roxzone to station to roxzone, with the right reps and distances per division. • Finds where you actually lose time. Per-run, per-station, and total roxzone splits surface the leak a whole-race clock hides. • Pay once, own it forever, across all your devices. FREE • Sequence timer with big, high-contrast, glanceable buttons. • Live splits and automatic roxzone tracking as you go. • Division presets: Open, Pro, Doubles, Relay. Everything editable. • Post-race summary: total time, every run, every station, total roxzone, slowest segment flagged. ROXSPLIT PRO (one-time unlock) • Target-pace mode: enter a goal finish time and see ahead or behind, live, the whole race. • PR vault: unlimited saved races, per-station personal bests, and a "vs. your best" overlay. • Pacing presets: even split, negative split, or bank-time-early models. • Station and partial-sim practice with the same split engine. • Export a race card image or CSV. No account required. • Apple Watch companion: advance segments and read splits from your wrist. Whether it's your first race and you just don't want to blow up, or you're chasing a PR and hunting the roxzone leak, RoxSplit gives you the number instead of the guess. Download RoxSplit and time your next Hyrox the way it's actually run. Payment will be charged to your Apple ID at confirmation of purchase. Subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period. You can manage and cancel your subscriptions in your Account Settings on the App Store after purchase. Any unused portion of a free trial is forfeited when purchasing a subscription.
