Readur turns anything you want to read into something you can listen to. Paste a link, share an article from Safari, import an EPUB or a PDF, scan a printed page with the camera, or just paste text. Readur pulls out the actual writing — no navigation, no cookie banners, no comment sections — and reads it aloud in a voice you choose. NINE NEURAL VOICES, RUNNING ON YOUR IPHONE Most reading apps hand you the same robotic system voice. Readur offers nine downloadable neural voices that sound close to a person: Heart, Thea, Nora, Nicole, Wren, Iris, Michael, Elliot and Silas. They run entirely on your device. No streaming, no server, no account — once a voice is downloaded it works on a plane, on the Tube, anywhere. Each voice lists its measured reading pace, from 101 to 174 words per minute, so you can pick one that suits the book rather than guessing. That number was measured, not estimated. BUILT FOR ACTUALLY LISTENING • Background playback, lock screen and AirPods controls • A sleep timer that fades out rather than cutting off • Speed from 0.8x to 2x • Follow along with the text as it is spoken, line by line • Pick up exactly where you stopped, in every document • Home Screen and Lock Screen widgets, and a Live Activity while you listen • Teach it how to say names and jargon it gets wrong YOUR READING STAYS YOURS There is no account and no sign-up. There are no analytics and no third-party tracking of any kind. Nothing you add to Readur and nothing it reads aloud is ever sent anywhere — speech is synthesised on your iPhone. The only two times Readur uses the network are when you give it a link to fetch, and when you choose to download a voice. That is the whole list. EVERYTHING IS FREE Every voice, every feature, no subscription, no unlock, no ads.

Verdict
The clearest difference is in-app purchases: Readur at none against TLDR Books's 1. On price, ads, device support and iOS requirement there is nothing between them.
