Stop Walking Back to Your Ball Machine: Better Ways to Control Solo Practice

A tennis ball machine should keep you hitting, not send you walking across the court every time something needs to change.

You start a backhand drill. The first few balls land a little too deep, so you stop, cross the court, adjust the machine and walk back. A few minutes later, you need a drink or want to change the pace. Another trip. The distance isn't the real problem; it's how often a small adjustment breaks your concentration and the rhythm of the drill.

The Tenniix App and Voice Controller put those controls closer to where you train. The App helps you prepare and fine-tune a session, while the Voice Controller armband handles quick interactions once you're on court. Recent updates also make it easier to find the right voice commands in the App and use them during practice.

One Session, Two Ways to Control Your Tennis Ball Machine

Think of the App and armband as parts of the same training flow. Before the first ball, open the Tenniix App to choose your training and review its settings. Set the ball speed, spin, placement, trajectory and feeding interval to suit what you want to work on. Then set your phone down and move into position.

Once you're on court, the armband puts quick tap and voice controls within reach, without requiring a trip back to the machine or repeated checks of your phone. If the balls are consistently landing too deep, or you want to change several settings for the next block, use the App again for a more detailed adjustment.

Use the screen when you need detail, and the armband when you need to keep moving.

Prepare the Drill in the Tenniix App

With Tenniix App 2.0, the route through training and custom settings is clearer. You can select what to practise, review the drill and make changes before stepping into your hitting position. In custom mode, the feeding interval can be adjusted from 1.5 to 15 seconds, so you can give yourself more time between balls when learning a movement, then shorten the gap as you get comfortable.

Suppose your goal is to recover to the middle after each backhand. You might begin with a longer interval so you can complete the movement without rushing. After a set, check how the drill feels and shorten the interval in the App if you're ready for a quicker rhythm. You can make that change from your side of the court, then get straight back to hitting.

The update also supports saving drill configurations offline, so you can prepare a setup ahead of time and return to it without rebuilding it each time. The App is where you see the full setup and make considered changes; the armband keeps common interactions close at hand while you play.

Voice Control for Your Tennis Ball Machine: Keep the Drill Moving

During an active set, you may only need a brief pause, a restart or a voice command. Those moments shouldn't turn into a walk back to the ball machine.

The same update extends beyond drill setup: it also refines how the armband responds to quick actions on court.

The updated armband offers one-tap pause and start. If a loose ball rolls into your path or you need a drink, a tap gives you a quick way to stop and resume. A short break stays short, and you can remain near your hitting position.

Voice gives you a second way to pause, and voice interaction has also become more flexible:

• Fewer words for certain commands. For commands such as “Game Pause”, you no longer have to say “Hi Tenniix” first. Some mode-entry sequences still begin with the wake phrase, so this is a shortcut for particular commands rather than a change to every voice interaction.
• More than one accepted phrasing. The armband recognises variations that mean the same thing, such as “shot test” and “test shot”, reducing the need to remember one rigid word order.
• Feedback when a command isn't recognised. An invalid-command response lets you know to try again instead of wondering whether the machine heard you.

These are small changes, but they matter when you're holding a racket, moving between shots and trying to keep your attention on the next ball.

Find the Voice Commands in the App

To help you use those voice controls, App 2.0 includes a Wristband Voice Guide. Choose the relevant mode to see its voice sequence and example commands in order. For instance, the guide shows when a mode requires “Hi Tenniix” before subsequent steps, rather than leaving you to guess which commands can be said directly.

This makes the App useful beyond drill setup. You can check the guide before a session, try the commands on court and return to it if you forget a phrase. As those commands become familiar, the armband lets you spend less time looking at your phone during the drill itself.

When Should You Use the App or the Armband?

In practice, you may move between them several times. Set up a drill in the App, start hitting, use the armband for a quick pause, then return to the App when you want to change the next block.

Less Operating, More Training

Remote control won't improve your backhand on its own. It can, however, make it easier to keep a useful drill going. When a setting is wrong, you can correct it instead of tolerating poor feeds because changing them feels inconvenient. When you need a quick break, you can take one without turning it into a trip across the court.

The result is a simpler pattern: set up, hit, recover, make the adjustment you need and continue. You stay focused on the ball and your movement while the controls remain within reach.

Frequently Asked Questions

• Can I adjust my tennis ball machine from the court with an app?

  Yes. You can use the Tenniix App for drill settings and adjustments from your side of the court. The Voice Controller armband also offers quick tap and voice controls on court.

• Do all voice commands work without saying “Hi Tenniix”?

  No. The update removes that prefix for certain commands, including “Game Pause”. Other voice sequences may still begin with “Hi Tenniix”. Check the Wristband Voice Guide in the App for the steps in each mode.

• What feeding interval can I set on the Tenniix ball machine?

  In custom mode, the feeding interval can be adjusted from 1.5 to 15 seconds. A longer interval gives you more time between balls when you're learning a movement, and you can shorten it as you get comfortable.

• Where can I find the voice commands for the Tenniix armband?

  Open the Wristband Voice Guide in the App and choose your mode. It shows the voice sequence and example commands in order, including where “Hi Tenniix” is required.

• Is the App or the Voice Controller better for solo tennis ball machine practice?

  They work best together. Use the App when you need to choose a drill, review settings or make a detailed change. Use the armband for quick tap and voice controls while you're on court.

Keep Your Position. Keep Your Rhythm.

The best training setup is one you can adjust without repeatedly stepping out of practice. With the Tenniix App for setup and detailed changes, plus the updated Voice Controller for quicker on-court interaction, you can spend less of your session operating your tennis ball machine and more of it hitting.
