In addition, the first 100 buyers will receive a limited Acemate gift bundle, including a branded bag and towel.

Human-Like Rally Experience

Unlike traditional ball machines that feed from a fixed position, Acemate S10 tracks incoming shots, moves across the court, catches the ball, and sends it back at speeds up to 100 km/h. Supported by 4K binocular vision and a 0.15-second response, Acemate S10 keeps the rally going with a more natural training rhythm. For players, that changes the session. Each rally asks them to adjust their timing, footwork, recovery, and shot selection instead of repeating the same feed. Players describe the experience as the closest thing to hitting with a real partner.

AI Coaching for Summer Practice

Summer is a strong season for tennis training, but players do not always have a hitting partner available or a coach they can book. Acemate S10 is designed to serve as both a rally partner and a training assistant with coaching-style feedback. With its built-in Drill System, players can train with clearer goals. The system includes 40+ training templates for NTRP 1.0 to 5.0, including forehand, backhand, volley, overhead, and more. Players can also create custom drills by adjusting feed interval, ball height, direction, speed, spin, and ball count. After each session, Acemate S10 provides training data and a session score, including shot placement, ball speed, net clearance, accuracy, and other key metrics. AI analysis then helps players understand their performance and identify what to work on next.

From Free Rally to a Complete Training System

Since launch, Acemate has revolutionized the tennis world by introducing a robotic partner that moves, receives, and returns shots like a real player. But as users trained more, a pattern emerged. Sessions often started without a clear goal. The only way to adjust difficulty was through manual parameter settings like depth, spin, and speed, which felt technical rather than intuitive. And when a session ended, there was no score, no summary, and no clear sense of what to work on next. Drill Mode is built to change that.

Introducing Drill System: From "Keep It In" to "Put It There"

Drill Mode is one of the biggest updates to Acemate since launch. Instead of simply keeping the ball in play, players now train with clear intent and measurable targets. It adds a structured training layer to the app where players set a target zone on the court and focus every rep on hitting that zone with precision. Acemate only receives balls that land within the designated area, keeping both player and machine locked in on the same skill. A Training Templates library has also been introduced, offering pre-built sessions designed for different goals and skill levels, so players can jump into focused practice without configuring parameters. Every shot is tracked, every session is scored, and every drill ends with a clear picture of where players stand. Together with Rally and Ball Machine modes, the Drill System creates a complete training setup—combining free play with structured, goal-driven practice.

A Complete Training Loop

The update touches every stage of a training session:

Get set: Pick a goal, not a parameter.

Instead of manually adjusting depth, spin, speed, and target zones, players browse Training Templates with pre-built sessions like mini tennis, cross-court drills, and down-the-line exercises, then go.

In the Drill: Every shot tracked, every target scored. Each shot is tracked in real time. The app displays live metrics including shot count, target hit distribution, average speed, and session duration. Because Acemate responds dynamically to each shot, drills combine targeted practice with the unpredictability of real match play.

Results in: A score, a breakdown, and a clear next step. Each session ends with a training score based on accuracy and quality, plus a detailed breakdown of shot accuracy rate, ball speed, and net clearance. This creates a full training loop—giving players clear feedback and actionable next steps after every session.

A Streamlined App for a Better Training Flow

Beyond Drill Mode, the entire app has been refreshed with a cleaner layout designed to make every session smoother.

The new Training Home puts modes and templates front and center, helping players get into training faster. Data Pages sit right alongside, so players can review session history, track trends, and compare results across drills as soon as a session ends. Machine controls for connection, positioning, and shot direction are now consolidated into a single Device tab, making setup and adjustments more intuitive. Players can also access guides, FAQs, and support through My Account, which now includes unit switching and language options for English, Chinese, Japanese, and Korean.

"Rally Mode showed us that players want more than just a machine that hits balls back. They want to know what to practice, whether they're getting better, and what to focus on next," said YI, CEO of Acemate. "That's why we built the Drill System. It's not just a new feature. It's a shift in what Acemate is here to do: help players actually improve, one session at a time."

"Our goal is to make Acemate feel less like a training device and more like a personal coach. With Drill Mode, structured templates, and post-session scoring, we're taking the first real step in that direction. There's a lot more to come."

The Road Ahead

Drill Mode is the beginning, the team is continuing to expand the Training Templates library while exploring a broader vision: a full tennis AI Coach. By bringing together video recording and stroke analysis, integrated training data, long-term progress tracking, and personalized recommendations, Acemate aims to evolve into a system that gives every player a training plan built around their game, and helps them get measurably better over time.
