ReadBack is a powerful, easy-to-use text-to-speech app built for writers, students, and professionals. Import your Word docs, PDFs, EPUBs, text files, or notes and let ReadBack read them aloud in voices designed to stay smooth and comfortable for long listening. Whether you’re proofreading chapters, reviewing lecture notes, or catching up on research during your commute, ReadBack makes it easy to keep up with your reading. Why people love ReadBack: - It reads real documents, from start to finish (yes, even full manuscripts) - Lifelike voices designed for hours of listening. - Plays in the background so you can multitask. - Unlimited replays of generated audio. - Great for catching awkward sentences, studying on the go, or giving your eyes a break. Privacy comes first: Your files are yours. After processing documents into audio, ReadBack doesn’t store your content on its servers. All of your documents and document audio live on your device only. Perfect for drafts, sensitive notes, or research. Subscriptions & Credits: Choose the plan that works best for you. ReadBack's subscriptions offer the best value for frequent listeners. But, for infrequent or irregular listening, try pay-as-you-go credits. They never expire. Why wait? Join writers, students, and professionals already using ReadBack to polish your work, focus better, and save time. Terms of use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
