Introducing Solo Mode™: Call Pitches With Just One Phone
The coach keeps the phone. The catcher wears the earbuds. Every call goes straight to their ear. No channel needed.
Solo Mode lets one phone run your whole setup. The coach holds the phone, the catcher wears the earbuds, and every pitch call goes right to their ear. No channel needed.
What is Solo Mode?
Not every team wants a phone for every player. Solo Mode™ is built for exactly that. Leave the channels off, keep one phone with the coach, and put a pair of earbuds on your catcher. Every pitch you tap on the Pitch Call Menu™ goes straight to their ear, read aloud, in real time. Your phone, your earbuds, nothing more.
What is Solo Mode?
Solo Mode™ is the Pitch Call Menu™ running on a single phone with no channel connected. When you are not joined to a channel, the send button automatically switches to Solo and your calls go to the devices paired to that phone: earbuds, a smartwatch, or both.
Pitch and zone selection work exactly the same as they do on a full team channel. The one thing Solo Mode™ leaves out is the open voice channel, so live two-way audio stays a Connected Mode feature.
One phone, one catcher, one device
This is the setup most small programs actually want. The coach holds the phone in the dugout and calls pitches. The catcher wears any Bluetooth earbuds you already own and hears each call the moment you send it. No second phone, no channel to manage, no device for every player. If a smartwatch is paired to the same phone, it gets the notification too.
What you need
- One phone with The Headset App installed (This is a “lite” version. Teams still need two (2) user licenses)
- One pair of Bluetooth earbuds (or an in-helmet speaker) for your catcher
- Optional: a smartwatch paired to the same phone
How Solo Mode works
- Open the Pitch Call Menu™. If you are not connected to a channel, the app is already in Solo Mode™ and the send button shows amber.
- Pick your pitch from the top row (Fastball, Curveball, Slider, Change, and any pitches you add yourself).
- Optionally choose a location on the Zone grid: the nine-box, or Up, Down, Off Plate Left, or Off Plate Right.
- Tap the amber Send button. Your call, “Curveball, low and away,” for example, goes to the earbuds and smartwatch paired to your phone, read aloud by voice.
Solo Mode™ is also the easiest way to build and test your menu. Send a call to your own earbuds and hear exactly what your catcher will hear before you ever step on the field.
Solo Mode vs Connected Mode
Both modes use the same Pitch Call Menu™. The difference is who hears the call and whether live audio is on.
| Solo Mode™ | Connected Mode | |
|---|---|---|
| Channel | None needed | Join a channel (up to six) |
| Send button | Amber | Green |
| Who hears the call | Your own devices (earbuds and smartwatch on this phone) *no live audio available in Solo Mode |
Everyone else in your channel, on their own devices. *You do not hear pitches on your own earbuds or watch |
| You hear your own calls | Yes | No (your earbuds stay on the live channel) |
| Live audio | Not available | Available, talk with your team while you send calls |
| Best for | One-phone setups, practice, testing your menu | Multi-user setups where each member has a device |
When coaches use Solo Mode™
- Game days with a single phone: coach calls, catcher listens, nothing else to set up.
- Bullpens and lessons: send calls to a pitcher or catcher working with you one-on-one.
- Practice reps: run pitch recognition and calling drills without connecting a whole channel.
- Building your menu: add your pitches and locations, then hear them read back before a game.
Ready to call live to your whole team?
When you are ready to bring the rest of your staff and players in, Connected Mode opens up voice channels, smartwatch notifications for everyone, and up to six channels for backups, the bullpen, and the press box. Solo Mode is a great place to start, and you switch the moment you connect to a channel.

Solo Mode™ FAQs
Solo Mode FAQ
Can I now use one (1) device in Solo Mode?
Yes! You no longer need a second device if you want to send pitches using the Pitch Call Menu™. However, if you still want to be able to talk directly to your players, you will still need a second device (like an iPad).Why can’t I hear (or see) my pitches on my own devices when I’m in Connected Mode?
Because The Headset App offers direct open-voice communication, when you enter a channel your earbuds reconnect back to your device and act as your mic and speaker, so you are not able to send pitches to your own devices.Why do I still need two (2) licenses?
Solo Mode is a “lite” version of The Headset App. It lets you send pitches to your own devices while you are not connected to a channel. Full open-voice communication, where you talk directly with your players, still needs two licenses.Trusted by Coaches Nationwide
