The user interface scale matters. Some apps offer a 'list view' that shows only text (title and author), which is ultra-lightweight. This is often the fastest way to navigate a massive library if you know what you're looking for. The graphical 'cover grid' view is more pleasant but more resource-intensive.
Having the option to switch between dense, text-only lists and rich, graphical grids is a sign of an app designed for scale. Power users might live in list view for management and only switch to grid view when casually browsing a specific, smaller collection.

ComiXology (well, now Kindle Comics) is actually amazing for offline comic reading. The guided view technology downloads with the comic, so you can still use that panel-by-panel view without a connection. For dense graphic novels, being able to zoom in on panels offline is a huge plus. If your 'novel' reading includes graphic novels, its specialised features put it ahead of general readers.

I've spent a lot of time exploring free offline reading apps with extensive libraries. My top pick is 'Libby' by OverDrive—it connects to your local library card, giving you access to thousands of e-books and audiobooks for free. The interface is sleek, and you can download books to read offline. Another great option is 'Project Gutenberg', which offers over 60,000 free classics, perfect for lovers of timeless literature.
For those who enjoy contemporary titles, 'Hoopla' is another library-based app with a vast collection, including comics and movies. If you're into indie authors or niche genres, 'Scribd' has a free trial that unlocks a massive library, though it eventually requires a subscription. 'Google Play Books' also has a 'Free' section with hidden gems, and 'Kindle' offers numerous free public domain books. Just remember to check permissions—some apps require an internet connection to initially download books before going offline.

For a no-frills, open-source option, Cool Reader on Android delivers a fantastically smooth offline experience. It's older, but it's rock-solid. It loads books from your storage instantly and flips pages with zero delay. It's not pretty, but if 'smooth' means 'fast and reliable,' it's a top contender.

Final thought (not really final, just another comment): Remember that 'large' is relative. What's large for one phone (200 books) is small for another (2000 books). Mention your actual approximate size when asking for advice. An app that works great for 500 might choke on 5000. For truly colossal libraries (10,000+), the only safe bet is a server-client model like Audiobookshelf, where the phone is just a thin client. For most people, 'Smart' or 'Voice' will handle up to a few thousand local files without issue on modern hardware.

Depends on your definition of 'free'. If you mean completely free with no hidden costs, 'Librera Reader' is a powerhouse. It supports a ridiculous number of formats (PDF, EPUB, MOBI, even comic book archives) and treats your device's folder as your library. I use it to read technical manuals and novels side-by-side. Since it's just a local file manager for documents, offline is its default, permanent state. No accounts, no subscriptions.
