Roxsplit: race-prep logbook

About this app

What Roxsplit does

Roxsplit is a race-prep logbook built around the exact shape of a Hyrox: eight 1km runs, eight stations, and the transitions in between. Instead of forcing your prep into a generic workout app that has never heard of a sled lane, Roxsplit gives every part of the race its own place — SkiErg, sled push, sled pull, burpee broad jumps, row, farmers carry, sandbag lunges, wall balls. The heart of the app is the simulation timer. Run a full or half sim in your gym and tap once at every changeover: each run, each station and each transition gets captured as its own split. Afterwards you see exactly where the time went — including the 'roxzone' transition minutes that quietly wreck most first-timers' finish times. Every station also keeps its own PR, history and technique notes, so over a training block you can watch your sled push drop from 4:10 to 3:20 and know the work is paying off. Before race day, set a goal finish time and Roxsplit lays out a target split for every run and every station, built on the even-pacing approach that consistently beats going out hot. After the race, log your official splits next to the plan and see precisely where you gained and where you faded — then build the next block around it. No account, no subscription, no coaching upsell. Roxsplit is 100% offline: everything is stored on your device with SwiftData and never leaves it. • Lap-style timer for full and half race simulations • Per-station PRs, history and technique notes for all 8 stations • Run, station and transition splits tracked separately • Goal-time pacing plan with target splits for race day • Race log with plan-vs-actual comparison • Fully offline, no account, free If you have a Hyrox on the calendar, download Roxsplit and start your first sim today.
