A HYROX race simulator built for race day

What you get

• Full 16-segment race: 8 × 1 km runs, each followed by a station, in official order
• Half simulations and single station + run combinations for focused practice
• Tap or swipe to finish each segment; undo the last split if you mis-tap
• Roxzone transition tracking, counted in your total time
• Screen stays awake with a haptic and audio cue on every segment change
• Pause, resume or abandon; your race survives a phone restart
• Works fully offline and syncs your results when you are back online

Practise the race, not just the workouts

HYROX rewards athletes who can hold a sustainable pace across 16 segments. A simulation shows you where you actually lose time: the run after the sled, the wall balls at the end, the transitions in between. FirstRox guides you through each segment in order, with the correct distance and, for your division, the correct weight shown on screen.

Built to be used mid-effort

The finish control is huge and works by tap or by swipe, so it still works with sweaty hands or gloves. A short guard stops accidental double taps from skipping a segment, and one tap undoes the last split. The timer is derived from the system clock, so locking the screen or switching apps cannot make it drift.

Understand every split afterwards

Your summary breaks the total into run, station and Roxzone time, which always add up exactly to your finish time. Compare against your target and your previous attempt on the same course, segment by segment, and see your best result at a glance.
