Bring your own Spanish books. Understand every word. Léelo is an EPUB reader for people whose Spanish is still a work in progress. Import any DRM-free Spanish ebook, tap a word you don't know, and get an English definition without leaving the page or losing your place. HOW IT WORKS Import from Files, iCloud Drive, or wherever your books live. Project Gutenberg, Standard Ebooks, and Wikisource are all free and all work. Tap a word for an instant English definition, its part of speech, and audio pronunciation. Tap again to save it to your vocabulary list. Tap a whole sentence for a natural translation plus a word-by-word breakdown, so you can see how the grammar actually fits together. It all runs on device. No account, no sign-in, and no internet needed once your dictionary has downloaded. WHICH BOOKS WORK Any DRM-free EPUB. That covers Project Gutenberg, Standard Ebooks, and anything you bought from a DRM-free seller. Copy-protected books will not work, in this app or any other. Books bought from Kindle or Apple Books only open inside those apps. Léelo checks before importing and tells you plainly when a file is protected, instead of failing halfway through. WHAT'S FREE AND WHAT'S NOT Free forever: 2 books you import yourself, every A1 graded reader, and 5 classics you pick. Premium: unlimited imports, all 296 graded readers from A1 to C2, and all 66 classics. 30-day free trial, then $5.99/month, or $49.99 once for lifetime access. If you plan to read a shelf of your own books, you want Premium. The free tier exists so you can read a real book start to finish before you decide. ALSO INCLUDED 296 original graded readers across the full CEFR ladder, A1 through C2, for when you'd rather build up to the hard stuff. 66 public-domain classics in Spanish. Reading streaks, saved words, and progress that syncs across iPhone and iPad through iCloud. Payment is charged to your Apple Account at confirmation of purchase. Your subscription renews automatically unless canceled at least 24 hours before the end of the current period; manage or cancel anytime in your App Store account settings. Lifetime is a single payment with no renewal. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://leeloreader.com/privacy/

Verdict
The clearest difference is in-app purchases: Blubb Reader at none against Léelo's 2. Blubb Reader also leads on iOS requirement (18.0 vs 26.0). On price, ads and device support there is nothing between them.
