You always think of the right thing to say afterward.

01The all-hands

The boss takes credit for your work in the all-hands. You freeze. Three hours later in the shower, the perfect line arrives.

Office · 2:47 PM→ Too late
02The dinner

Your mother brings up the wedding. Again. You go silent and seethe through dessert.

Family · Sunday→ Resentment
03The raise

You're owed a raise. You've been owed it for nine months. The meeting is Tuesday. You've rehearsed nothing.

Frequently · Asked

The small print, plainly.

Q.01Which devices does it run on?+
Nerve Arena is on the App Store for iPhone and iPad (iOS 15 and up) and on Google Play for phones and tablets (Android 7 and up). Your roster, replays and stats sync across both.
Q.02Is this therapy?+
No. Nerve Arena is a practice tool, not a mental-health service. If you're working through something heavy, please talk to a professional. We'll still be here when you want to rehearse the next hard conversation.
Q.03How is this different from ChatGPT?+
ChatGPT helps you. The opponents in Nerve Arena fight you. They're designed to be difficult: to deflect, gaslight, and pressure, so the real conversation feels familiar when it lands.
Q.04What does it cost?+
Core sparring is free. A paid tier (Nerve Pass) unlocks advanced personas, campaigns, and unlimited replays. One subscription covers iOS and Android.
Q.05Can I suggest a persona?+
Yes. Every player gets a crack at the Forge, our community-built persona system.
