I've tested countless apps for annotations and free access. The best I've found is 'Moon+ Reader' for Android—it supports highlights, notes, and even exports them. Another solid pick is 'Librera Reader,' which handles EPUB and PDF annotations seamlessly. For iOS users, 'Apple Books' is surprisingly robust with its underline/note features.
I also adore 'Cool Reader' for its simplicity and cross-platform sync. 'FBReader' is another gem, especially for public domain books, though its annotation tools are basic. If you’re into classics, 'Project Gutenberg’s official app' lets you bookmark and annotate freely. Just remember: most 'free' apps have ads or limitations, but these strike a good balance between functionality and cost.

I've tried countless apps for annotating books, and 'Moon+ Reader' stands out as a top choice. It's packed with features like highlighting, underlining, and adding notes directly to the text. The interface is clean and customizable, making it easy to organize thoughts while reading. I also love how it syncs across devices, so my annotations are always accessible. Another great option is 'Librera,' which supports EPUB and PDF formats seamlessly. It allows users to highlight passages, add bookmarks, and even draw on the pages. Both apps are free with optional premium upgrades, but the free versions are more than enough for avid readers who love to jot down their thoughts.
For those who prefer a more minimalist approach, 'Google Play Books' is a solid pick. It offers basic annotation tools and integrates well with other Google services. However, 'Moon+ Reader' remains my go-to because of its advanced features and smooth performance. If you're into classics or public domain works, 'Kindle' also has decent annotation features, though its free selection is more limited compared to others.

Being a bookworm who’s constantly juggling between physical copies and digital libraries, I’ve experimented with a ton of ebook apps over the years. Annotation features are a game-changer for me—I’m the type who underlines quotes, scribbles reactions in margins, and dog-ears pages (digitally, of course!). Most free readers like Kindle, Google Play Books, or even lesser-known apps like Moon+ Reader do offer basic highlighting and note-taking. But the depth varies: Kindle syncs annotations across devices seamlessly, while some indie apps might only save locally. I once lost hours of notes on a PDF in a barebones app because it didn’t back up to the cloud. Pro tip: check if the app exports annotations—I love pasting my highlights from 'Project Hail Mary' into Notion for later reference.
That said, advanced features like layered highlights or drawing tools are usually paywalled. Adobe Acrobat’s free version lets you doodle on PDFs, but for EPUBs, you might need to upgrade. If you’re academic or a deep analyzer, apps like LiquidText (though not entirely free) blow the basics out of the water with mind-mapping annotations. For casual readers, though, free options cover the essentials. Just remember to double-check autosave settings—nothing stings like losing your epic theory about 'The Three-Body Problem’s' dark forest hypothesis mid-read.

Honestly, the dictionary in 'Apple Books' is so fast it's ruined other apps for me. You don't even need to highlight; just tap a word and the definition slides up from the bottom. Adding a note is two taps away. It's so frictionless that I actually use it, whereas in other apps I'd be too lazy.
The organization is simple: all your notes and highlights are in a list view per book. It might lack advanced tagging, but for most people, that's more than enough. Since it's pre-installed and free, it's always my first recommendation to iPhone and iPad users. No account needed, no ads, just immediate utility.

Onyx Boox devices have their own app store, but their default Neoreader app is insane for annotations—but that's hardware. Their Android-based readers let you install any Android reading app. So if you're thinking of a dedicated e-ink device later, choose a free app now that also works on Android, so your library can transfer.

I’ve found digital annotation tools to be a lifesaver. My absolute favorite is 'Moon+ Reader,' which not only lets you highlight and add notes but also syncs across devices—perfect for switching between my phone and tablet. For PDF lovers, 'Xodo' is a powerhouse with its free annotation features, including text highlights and handwritten notes.
If you’re into classics or public domain works, 'Librera' is a hidden gem that supports EPUB and PDF with robust annotation tools. For a more social experience, 'Hypothes.is' lets you annotate web pages and even collaborate with others, though it works for some eBook formats too. Each app has its quirks, but they all make reading more interactive without breaking the bank.

PDF annotations are a game-changer for me, especially when I'm knee-deep in research or just trying to organize my thoughts on a dense academic paper. The best reading apps like 'Adobe Acrobat Reader' and 'Foxit PDF Reader' absolutely nail this feature—highlighting, sticky notes, even drawing tools are all there. But what really impressed me was how 'MarginNote' merges annotations with mind-mapping, turning a static PDF into this interactive workspace. I once spent hours annotating a fantasy novel for a book club, and the ability to link lore notes across pages felt like cheating.
That said, not all apps handle annotations equally. Some free versions limit how many annotations you can save or lack cloud sync, which is frustrating if you switch devices mid-project. And let’s not forget compatibility: I’ve lost annotations before because the app didn’t play nice with certain PDF formats. For serious work, I’d always check if the app supports industry standards like PDF/A or encrypted files. Still, when it works, there’s nothing like revisiting a highlighted passage years later and seeing your past self’s scribbles.
