HitOne - 3D Tennis Drills

Design a drill like a coach, then step onto the court and play it in 3D — all the way into the player's own eyes.

HitOne turns your tennis ideas into living 3D drills. Lay out the feeds like a coach at the basket, press play, and watch the rally unfold in a stadium — from the stands, from behind the player, or through their eyes.

BUILD DRILLS LIKE A COACH • Place every ball exactly where you want it — tap the court to set where the feed lands and where the answer goes • Chain shots into patterns, repeat them with loops, and add random pools that feed one surprise ball each time • Set speed, difficulty and intent for every shot — the colors carry onto the 3D balls, so patterns read at a glance • Give the coach and player speech bubbles for extra fun

WATCH IT IN 3D • A full indoor arena plays your drill with a coach feeding and a player answering • Five cameras: Broadcast, Baseline, Player, Coach and Side • Pinch into the Player camera until you're watching through the player's own eyes • Pause, scrub, restart, or run it at double speed

START FAST • A library of ready-made preset drills, sorted by what you want to train • A guided tutorial builds your first drill with you, step by step

YOURS EVERYWHERE — OR JUST ON YOUR PHONE • No account needed: build and play fully offline • Optional sign-in (Apple, Google or email) syncs your drills across your devices • Delete your account and data any time, right from the app

Whether you're a coach sketching tomorrow's session, a player visualizing patterns, or a tennis parent feeding balls on Saturday mornings — if you can imagine the drill, you can watch it played.
