How do Boosters work in the app?
Boosters are a different way to build fluency alongside the Signature Box Program.
The Signature Boxes deepen fluency by helping your family use connected language patterns in more and more ways. Boosters broaden fluency by helping your family add full phrases across specific topics and situations.
Use the Signature Boxes as your main path, and mix in Booster phrases whenever you want to add language that’s especially useful for your family right now.
Where do I find my Boosters?
Tap Boosters near the top of the home screen.
Choose the Booster you want to practice from.
How do I practice a Booster Focus Phrase?
Booster Practice Sessions follow the same practice flow as your Signature Box Practice Sessions.
Do Boosters have Warm Ups?
No.
Boosters don’t have Warm Ups because their phrases can cover more varied topics.
Warm Ups are part of the Signature Box Program because the phrases within a Box are designed to build on one another within a similar topic.
Instead, Booster phrases come back through Reviews.
How do I switch to a different Booster?
On Practice → Boosters, tap the down arrow next to your current Booster/Practice Session.

Then tap the Booster where you’d like to start your next Practice Session.

You can switch to a different Booster before you start practicing with the audio or after you finish using your current Focus Phrase in real life.
If you already started the Practice Session, finish the remaining steps first:
- Complete Practice in a Situation
- Complete Practice with Emotions
- Use your Focus Phrase in real life
- Tap the + next to Used in real life!
Once you’ve marked the phrase as used, you’ll be able to switch to another Booster.

If you choose a Focus Phrase in one Booster, then switch to another Booster before practicing, your phrase choice stays saved. This lets you plan phrases from different guides ahead of time without losing what you already picked.
How often should I practice from a Booster?
If you’re also working through the Signature Box Program, you might choose a Booster Focus Phrase 2–3 times a week alongside your Box Practice Sessions.
There’s no need to finish a Booster before continuing through your Boxes. You can move between the two as you build the language you want your family to use.
How do Booster Reviews work?
Each Booster keeps its own Review Sets, so phrases from different Boosters aren’t mixed together.
A new Review Set begins with the first Focus Phrase you practice from that Booster.
As you continue practicing, your Focus Phrases are added to that Review Set.
Once a Review Set reaches 10 phrases, it closes. The next Focus Phrase you practice begins a new Review Set.
You’ll find these under the Boosters tab in Review.
Can I find a Booster phrase again later?
Yes.
Once you’ve practiced a Booster Focus Phrase, it will appear in Recent.
Tap Recent, search for a word from the phrase, and play the native-speaker audio whenever you want help recalling it.
Your practiced Booster phrases will also continue coming back through Reviews.
