Audella

Audella reads the world aloud. Point your phone at a sign, a letter, a label on a medicine bottle, or a page of a book — and in seconds, Audella reads it back to you. Built for anyone who wants to keep reading: low vision, tired eyes, dyslexia, or simply a long page you'd rather listen to. CAN WORK FULLY OFFLINE The free app runs entirely on your phone. On a plane, on a bus with no signal, in a kitchen with no Wi-Fi. No account, no sign-up, nothing to create. • Read anything aloud — aim the camera at any printed text and hear it spoken back. • Build a book, one page at a time — snap a page, then another; Audella keeps them in order so you can pick up where you left off. • Translate offline between 31 languages — capture a page in one language and have it read in another. A letter from abroad, brought back in your own language. • Curated offline voices — download a nicer voice for your language (about 30–60 MB, once) that sounds far less robotic than the default. • Cover detection, auto-rotation, and page cropping — hold the phone any which way; Audella straightens the page and trims the edges, even when hands aren't steady. Everything above works offline, forever, with no subscription. PRIVATE BY DESIGN No accounts. No profiles. Free reading happens on your device — we can't read what we never receive. PREMIUM — WHEN YOU WANT IT TO SOUND BEAUTIFUL Premium uses the latest online narration and translation, for the days you want the very best: • Natural narration — voices that sound like a real human narrator, male and female. • Reads handwriting — cursive, messy notes, doctor's notes, a card from your grandchildren — not just printed text. • Adaptive reading — Audella senses prose vs. poetry and changes its pacing to match. • Character voices — the narrator and each character can have their own voice, closer to an audiobook. • Chapter detection — jump straight to "Chapter 4." • Audiobook-style controls — audio keeps playing when the phone locks; play, pause, and skip from the lock screen; speed from 0.75× to 1.5×. • Premium translation — handles idioms, names, and tone far more gracefully. Once a book is narrated with Premium, the result lives on your phone — listen again anytime, offline, without spending more credits. You can even share a narrated book with family, who can enjoy it without a subscription of their own. The free app keeps you reading on its own. Premium is there for the days you want it to sound beautiful. — Audella Premium is an optional auto-renewing subscription (monthly and yearly plans, several tiers). Payment is charged to your Apple ID at purchase; it renews automatically unless auto-renew is turned off at least 24 hours before the period ends. Manage or cancel in your App Store account settings.

The clearest difference is iOS requirement: Audella at 16.0 against PDF Reader's 18.1. On price, update cadence, ads and in-app purchases there is nothing between them.
