## What is Renobo?

Built by a reader, for readers.

A reader that only reads
Most reading apps keep piling on features until you need a manual just to turn a page — and then they ask for a subscription. Renobo does one thing: it gets out of your way so you can read. No ads, no tracking, a clean interface, and battery use kept as low as we could get it. Every book remembers its own font size, spacing, and page-turn style, so you never have to reset anything when you switch titles.

Read books in any language, not just the ones publishers translate
Most of the world's books never get a translation into your language — and most books in your language never reach anyone else. Renobo runs a purpose-built translation engine: even the free translator on your phone, guided by our context-handling technology, keeps character and place names consistent and holds a coherent tone across the whole book — none of the disjointed, sentence-by-sentence feel of ordinary machine translation. Want it even closer to a human translator? Bring your own language-model API key, or subscribe to our translation plans, priced to be worth it. Translate once, then read offline forever — for the price of nothing, or next to nothing, you get to read almost anything.

Comics and manga, stripped down to what matters
A comic reader doesn't need a hundred settings — it needs to disappear. Renobo gives comics and manga a minimal, full-screen, immersive mode: pages are auto-detected, wide spreads are split automatically into single pages, and .cbz/.cbr files just open — no unzipping, no folder wrangling.

Every format, no lock-in
EPUB, MOBI, PDF, TXT, Markdown, CBZ, CBR — one app opens them all. Bring files in however you like: direct import, Wi-Fi transfer, cloud drives, local network sharing, or a direct link. Your books, your way, no platform lock-in.

iCloud sync across your devices — With the same Apple ID, your entire library, reading progress and finished status, notes and bookmarks, and your reading, text-to-speech and translation preferences stay consistent across iPhone and iPad. Imported books travel between devices through iCloud and download on demand, without taking up local space. Turn sync on or off by category (books, settings, statistics, and more); sensitive data like account keys stays off the cloud by default. Switching to a new device or using several at once just works.

The small things that matter
· Free text-to-speech with synced highlighting and lock-screen controls
· Highlights and notes that jump straight back to the source
· Reading stats and progress at a glance
· 13 interface languages
· Bookshelf folders that pick up right where you left off

Pricing, plainly
Renobo is fully usable for free, including the free translation engine — you never have to pay. A one-time purchase unlocks advanced features like the higher-quality translation pipeline and comic mode. If you want language-model-grade translation, a monthly subscription is available — never required, and it changes nothing about the free reading experience if you skip it.

I've read for years and built software for longer. This is the reader I wanted for myself. Now it's yours.

Subscriptions, plainly
Subscriptions renew automatically each month and can be canceled anytime in your App Store account settings.
