Your child becomes the hero. Iskra Worlds turns your child into the star of their own ongoing audio series. Their real family plays the supporting cast, a companion they choose and name is at their side, and every episode is a brand-new adventure set in worlds they picked themselves. HOW IT WORKS 1. A grown-up sets everything up in about two minutes: the child's name and age, and the family members who will appear in the stories. 2. Your child picks a companion — a fox, an owl, a little dragon, a rabbit, a robot or a turtle — and gives it a name. 3. They choose their worlds: Pirate Cove, The Star Roads, The Dinosaur Frontier, The Undersea Deep, The Wildwood, The Skyport, The Velvet Theater, The Storybook Library, The Lantern Market. 4. From then on, new episodes arrive twice a week, ready to play. Every episode is a complete, self-contained story around six to seven minutes long — a real adventure with real stakes, told warmly and narrated aloud. Perfect for bedtime, car rides, quiet time, or any moment that calls for a story instead of a screen. WHAT YOU GET • 2 new personalized episodes every week — 8 each month • The first story is free • Every episode stays in your library, ready to replay as often as your child likes • Save episodes for offline listening • Stories available in English, Croatian, Macedonian and Serbian • Designed for children around ages 4–9, with age-appropriate storytelling MADE FOR PARENTS You create the account, you enter the details, you stay in control. Settings and purchases sit behind a parental gate, so children can do exactly one thing in the app: listen. SUBSCRIPTION Iskra Unlimited is a 1-month auto-renewable subscription. Payment is charged to your Apple account at confirmation of purchase, and the subscription renews automatically at the price shown in the app unless cancelled at least 24 hours before the end of the current period.

Verdict
