About

Sofio

Read full description

Your child taps a dog and hears your voice say "Dog!" In Sofio, you record the names and clues that turn illustrated animal and vehicle worlds into personal learning games. Made for toddlers, preschoolers and the grown-ups who know them best, Sofio brings familiar voices to gentle picture discovery. Start with one recording and add more at your own pace. RECORD. EXPLORE. FIND. EXPLORE: Your child taps a subject, hears your saved recording, then sees its playful response and hears its sound. FIND IT!: Record a clue such as "Where is the dog?" Your child listens and taps the matching picture. A correct answer replays your EXPLORE recording. Gentle hints encourage another try, with no scores or countdowns. YOUR FAMILY'S WORDS Say a name, share a little fact or make up a clue about what your child can see. Record in the language your family uses. Suggested phrases help you begin, and you can listen back or replace a clip whenever you like. A grown-up creates the voice recordings; Sofio does not supply a prerecorded narrator or listen to your child's answers. The app interface is in English. A world without recorded FIND IT! questions opens in EXPLORE. TWO WORLDS INCLUDED Farm Animals and Vehicles are included. Optional one-time purchases unlock Dinosaurs, Aquatic Animals, House Animals, Wild Animals and Insects individually. Each available world has eight subjects, illustrated scenery and individual reactions: 56 subjects across seven worlds when all five optional worlds are unlocked. Fruits and Vegetables are Coming soon previews, not playable worlds in this version. No subscription is required. PARENT CONTROLS, GENTLE PLAY Choose the play mode, manage recordings and adjust background music in the parent area. A grown-up check, with an optional parent PIN, protects parent settings and purchase access. No advertising, child accounts or social sharing. RECORDINGS STAY ON YOUR DEVICE Microphone permission is requested when you choose to record. Sofio does not upload your recordings to the developer. Device backups may include app data. Delete individual clips or all recordings from the parent area. Created by a father for his daughter, Sofio makes room for the voice your child already knows.
