Lexton – Shared Reading, Growing Together Subtitle Turn every reading moment into a warm memory of growth. Description Lexton is a warm companion for parent‑child reading. It goes beyond simply recording “what books were read” — it captures the moments, feelings, and growth that come with each shared reading experience. From the first book to the hundredth, from you reading aloud to your child, to your child reading back to you, Lexton helps nurture a lifelong love of reading. Warm Companion, From the Heart 1. Family Accounts – Share the Journey Each family member can have their own reading space. Parents track their own reading, while children enjoy their own bookshelf — simply switch accounts to explore different reading worlds. Parents can always stay connected to their child’s reading progress and share the joy together. 2. Reading Journey – Celebrate Progress Every reading session is a step forward. Based on cumulative reading time, children unlock achievement levels: Seed, Sprout, Sapling, Tree, Forest — each with unique icons and progress bars, encouraging kids to grow into their own “reading forest.” Fun badges reward consistent reading, time spent, excerpts, and check‑ins. Every effort is recognized, every milestone celebrated. 3. Reading Check‑Ins – Capture the Moments Set a start and end time, and Lexton automatically logs your reading duration. Every cozy session is faithfully recorded. You can note pages read, rate the book, and jot down your thoughts — treasures to look back on for years. 4. Growth Analytics – See the Progress Clear charts show reading time, check‑in frequency, and book preferences — an at‑a‑glance view of your child’s reading habits. At year end, Lexton generates a personalized Annual Reading Report, revealing your reading keywords, the most‑read book, and more. 5. Excerpts & Notes – Keep the Memories Save the sentences that made your child giggle, or the passages that touched your heart. Snap a photo of the page to extract the text, add notes, and capture your thoughts. Revisiting them later is like opening a jar of sweet memories. 6. Share the Joy – Spread the Warmth Turn reading journeys, achievement badges, annual reports, and favorite excerpts into beautiful images — easily share with family, friends, or on social media. Those precious reading moments become heartwarming conversation starters. 7. Book Management – Smart OCR Support Easily manage your home library. Scan a book cover to automatically recognize the title, author, publisher, and more — add it in one tap. Manually add, edit, or mark reading status to build your own digital bookshelf. 8. iCloud Sync – Never Lose a Memory All data is automatically backed up via iCloud, so your records stay safe and seamlessly sync across devices — stored securely in your own iCloud space. Lexton is here to walk alongside you and your child on your reading journey. Let every shared story become a cherished memory of growth.
