What is inside

Voice callouts, reaction timing, rounds, randomizer, sharing and offline training — ready to use.

Custom voice commands

Numbers, colors, directions, punch labels and mic-recorded samples — with TTS speed control.

Reaction time, measured

The phone microphone hears your strike on the pads or bag and times it from the called command — per command, per round, in milliseconds. Calibrate each command with three strikes; sound is never recorded.

Advanced interval rounds

Prep, round, end-warning and rest — tuned for boxing, MMA or any fitness interval work.

Smart randomizer

Fixed or random callout gaps, no consecutive repeats, unique-in-combo rules and shuffle coverage.

Combos & sequences

Single signals, multi-hit groups, cross-category mixes with exclusions, or ordered scenarios.

Live session coach

Full-screen workout UI with pause, skip, mute, large command display, beeps and wake-lock.

Flash & flashlight cues

On-screen flash modes and optional device flashlight synced to every command.

Themes for every setting

Per-workout looks: dark, light, high-contrast outdoor and neon — pick what stays readable in the gym, sun or low light.

Activity & streaks

Streak, workouts, time and commands over 7–30 days, schedule filters, and a workout log with your reaction trend for 7 days, 30 days and all time.

Frequently asked questions

How do I install it on Android?

Get it on Google Play and tap Install — updates come through Play automatically.

Does it need an internet connection?

No. Training runs fully offline. Internet is only needed if you choose to sync an account.

Can I use it on iPhone?

Yes — open the web app in Safari and add it to your Home Screen. It then opens full-screen like a native app.

Is there a free plan?

Yes. Free includes core training with built-in commands. Pro and Coach unlock higher limits for custom content and advanced callouts.

Is it an interval or round timer?

Yes. Rounds & Commands is a fight coach that also works as a boxing, kickboxing and MMA interval and round timer. Set prep, round length, an end warning and rest — the voice coach calls combos and cues while the round clock runs.

Does the round timer include voice callouts?

Yes. During each round the voice coach calls punches, combos and reaction cues, with beeps and your own commands. It is a sparring coach and a round timer in the same session, not a silent clock.

Can it measure my reaction time?

Yes. Turn on reaction measurement in a training: the microphone hears each strike and records the delay from the called command to your hit. The workout log shows average, best and slowest per command, every strike with its round and time, and your 7-day, 30-day and all-time averages. A false reading can be excluded by hand. Audio is processed on the device and never recorded.
