About

Boxerium

Read full description

Boxerium is a boxing round timer built for people who actually train. BUILD WORKOUTS YOUR WAY Set the work and rest seconds for each round. Add as many combos to a round as you want — anything from "jab cross" to "slip jab cross hook to the body". Boxerium picks one at random and calls it out at the interval you choose. Every round can be different. DRAG-AND-DROP COMBO BUILDER Every punch, every body variant, every defensive move. Drag a technique into a combo or tap to add. Jab, straight, cross, lead hook, hook, flying hook, check hook, lead uppercut, uppercut — plus a body variant of each. Slips, rolls, pivots. High block, parry, catch, shoulder roll, cover up, low block. YOUR WAY OF CALLING THE SHOTS Prefer numbers? Flip the toggle in Settings and Boxerium will say "1, 2, 3" instead of "jab, cross, hook". Don't like the default voice? Pick any of the voices already installed on your iPhone. REAL ROUND BELLS Bell on round start. Bell on round end. Ten-second heads-up before the buzzer. The screen stays on so you don't miss a callout. NO ACCOUNT Your workouts save on the device. No login. No subscription. A single banner ad on the home screen — one-time purchase to remove it if you want it gone. Train shadow. Train heavy bag. Train mitts. Build the round you want, then box. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
