VoiceXP is a playful voice and breathing app for children built around calm, curiosity, and low-pressure exploration. Originally created by a parent to support a child with Selective Mutism and Autism Spectrum Disorder, VoiceXP is designed to complement strategies used by families, educators, and speech professionals. Sound Play tab: Animated, mood-responsive activities let children explore breath length, volume, and sound — without the pressure of speaking words. The focus is curiosity, not performance. Unwind tab: Quiet visuospatial games, a creative sandbox (My Quiet World), and three guided breathing experiences help children settle and find a calm starting point. Progress: A simple weekly overview tracks breathing and voice engagement, with personal milestones for each location. Multiple profiles supported on one device. All progress is stored locally. No personal data is sold or shared. EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
