What's the best iOS app for making bedtime stories interactive with sound effects?

Readmio is an iOS app that specializes in enhancing read-aloud experiences for children by integrating sound effects into stories. It works by allowing parents or the app itself to narrate tales, with audio cues like animal noises or environmental sounds that trigger at specific moments in the text. This feature is particularly useful for bedtime, as the immersive elements can hold a child's attention and help transition them to sleep. Reviews indicate that many families appreciate the variety of stories available, which include options for different ages and interests, and the ability to switch between automated narration or parent-led reading. However, some users report that sound effects occasionally last too long or vary in volume, which might startle quieter children. Additionally, the app lacks extensive visual components, making it less ideal for toddlers who rely on pictures. Despite these minor drawbacks, Readmio provides a practical tool for parents seeking to make storytime more dynamic without overwhelming complexity.
