Turn screen time management into a warm "Digital Contract." Screen time shouldn't be about cold "restrictions"; it should be about visible "progress." LockFlow introduces a unique "Request & Approve" model, empowering children to earn rewards through effort while allowing parents to respond to growth with trust. Listen to their voices and witness their achievements—making every unlock a positive milestone. 【Core Features】 • Voice Requests: Hear the "Promise" Need 15 minutes of gaming? Let them tell you why. Whether they finished homework early or want to share a moment of joy, the warmth in their voice makes communication real—no more cold, rigid digital limits. • Photo Proof: Witness Every Achievement From a completed assignment to a tidy room, your child can snap a quick photo as "Proof of Effort." This real-time delivery makes rewards well-earned and self-discipline tangible and rewarding. • Remote Real-time Response: Stay Connected, Anywhere In a meeting, at work, or on the go? Receive requests instantly on your iPhone or Apple Watch. Quickly preview photos and voice messages to respond to your child’s effort with a simple, seamless flow. • Dual-Device History: A Journal of Growth All requests are securely stored on your family devices. This isn't just a log of self-discipline; it’s a dedicated digital journal documenting your child’s journey toward independence. 【Privacy & Commitment】 • Your Data Stays Yours Built on Apple’s private cloud technology, LockFlow adheres to a "Zero-Server" architecture. Photos and voice messages stay within your family's devices. We cannot see, hear, or store your personal data—complete sovereignty remains with your family. • Professional System Shield Leveraging the latest native technologies, LockFlow provides a stable and reliable digital boundary without interrupting daily life, helping children build self-discipline habits that last a lifetime.
