I read 40-50 books a year. Half on Kindle, half on my phone during commutes and waiting rooms. I’ve tried every reading app and most e-readers.

Most reading software is solving problems nobody has. Highlighting in 17 colors. Social features. Gamification. Reading streaks.

I spent six months testing eight reading apps and three new e-readers to figure out what actually matters.

E-Readers: The Hardware

Kindle Paperwhite (2024 model, $150) — Still the default choice. Good screen, solid backlight, huge Amazon ecosystem. Battery lasts weeks.

The problems haven’t changed: locked to Amazon, no library lending (unless you live in the US), proprietary format. If you’re all-in on Kindle books, it’s great. If you want flexibility, it’s limiting.

Kobo Libra Colour ($230) — Color e-ink, supports EPUBs natively, OverDrive integration for library books. Slightly worse screen than Kindle, better openness.

I used it for two months. The color is subtle — good for book covers and charts, not photos. Library integration is excellent (I borrowed 12 books without leaving the couch).

If you want to avoid Amazon lock-in and use library books, this is the best option in 2026.

reMarkable Paper Pro ($579) — E-ink tablet marketed for reading and note-taking. Beautiful hardware, absurd price.

I tested it for a month. The reading experience is good but not $400 better than a Kindle. The note-taking is excellent but doesn’t justify $579 unless you’re replacing both an e-reader and a paper notebook.

Most people should skip this. It’s for a very specific niche (people who read technical PDFs and take extensive notes).

Reading Apps: iOS/Android

Apple Books (Free, iOS) — Built-in, clean UI, supports EPUBs. Highlights sync via iCloud. The store is smaller than Kindle but has most major titles.

If you’re in the Apple ecosystem and don’t need Kindle exclusives, this works fine. I used it for three months. No complaints, but nothing special.

Kindle App (Free) — Syncs with Kindle hardware, huge store, notes and highlights sync. The iOS app is fine. Not beautiful, but functional.

The reading experience on an iPhone screen is inferior to any e-reader, but it’s always with you. I read 15 books on the Kindle app last year, all during idle moments (waiting for appointments, commutes, lunch breaks).

Libby (Free) — Library lending app (OverDrive). Borrow e-books and audiobooks from your library. Return early or let them auto-return at the due date.

This is essential. I read 20 library books last year via Libby. Zero cost, zero guilt about unread purchased books piling up.

The UI is excellent. Better than Kindle or Apple Books. The selection depends on your library system, but most have thousands of titles.

Readwise Reader ($10/month) — Read-it-later app with e-book support. Import EPUBs, PDFs, articles, newsletters. Highlights sync across everything.

I subscribed for three months. The highlight system is genuinely excellent. Automatic tagging, export to Notion/Obsidian, daily email review of past highlights.

The problem: $10/month for a reading app is steep. I cancelled after realizing I was paying for features I used weekly, not daily. Worth it if you’re a heavy highlighter and knowledge management person. Overkill for casual readers.

Kobo App (Free) — Companion to Kobo e-readers. Similar to Kindle app, but for Kobo’s ecosystem. Fine but unremarkable.

Play Books (Free, Android) — Google’s reading app. Supports EPUBs and PDFs, uploads to cloud, syncs across devices. Works well if you’re on Android and don’t want Kindle.

Moon+ Reader ($6 one-time, Android) — Highly customizable reading app. Gesture controls, themes, TTS, EPUB/PDF support. Ugly but powerful.

I tested it for two weeks. If you want control over every aspect of reading experience (fonts, margins, line spacing, page turn animations), this is it. For normal people, it’s overwhelming.

What Actually Mattered

After six months, here’s what improved the reading experience:

E-ink screens. Reading on a phone is fine for 20 minutes. For an hour, e-ink is noticeably easier on the eyes. The Kindle Paperwhite and Kobo both deliver.

Library integration. Libby on my phone + Kobo e-reader with OverDrive = I read 30 more books last year than I would have otherwise. Free books remove the “I spent $15, I should finish this even though I hate it” problem.

Sync across devices. Start reading on e-reader, continue on phone during lunch, finish on iPad in bed. Kindle and Apple Books both handle this well.

Simple highlights. I highlight passages I want to remember. The ability to export highlights (Readwise, Kindle notes, Apple Books) is useful. Color-coding and tagging is not.

What Didn’t Matter

Social features. Goodreads integration, friend recommendations, reading clubs. I tried engaging with these. Stopped after three weeks. Reading is solitary for me.

Reading goals/streaks. Some apps gamify reading (daily streaks, page count goals). This makes reading feel like a chore. I read when I want, as much as I want.

Fancy typography. Readwise and Moon+ let you customize fonts, spacing, margins to absurd degrees. I spent an hour tweaking settings, then realized default fonts were fine all along.

Audio integration. Kindle’s “switch between reading and audiobook” feature sounds useful. In practice, I never used it. Audiobooks and reading are different contexts for me. A friend who runs business AI solutions reads technical documentation during commutes and switches to audiobooks for fiction—totally different use cases.

The Real Recommendation

Best e-reader for most people: Kindle Paperwhite ($150). Ecosystem is huge, hardware is solid, everyone knows how to use it.

Best e-reader for library users: Kobo Libra Colour ($230). OverDrive integration is worth the premium.

Best reading app for casual readers: Libby (free) for library books, Kindle app (free) for purchased books, Apple Books (free) if you’re on iOS and want to avoid Amazon.

Best reading app for power users: Readwise Reader ($10/month) if you highlight extensively and do knowledge management. Overkill otherwise.

Best budget option: Buy used Kindle Paperwhite on eBay ($60-80), use Libby for free library books, Apple Books or Kindle app on your phone. Total cost: under $100 for years of reading.

The Honest Take

E-readers are worth it if you read more than 10 books a year. The screen quality and battery life justify $150.

Reading apps mostly don’t matter. Your phone’s browser or default books app is fine. The content is what matters, not the container.

The only app worth paying for is Libby, and that’s free. The only hardware worth buying is a basic e-reader (Kindle or Kobo).

Everything else — fancy apps, premium features, color e-ink, note-taking tablets — is nice to have at best, wasteful at worst.
