Short answer: the best legal manga app depends on what you read. MANGA Plus (Shueisha) is the standout free option — new chapters at the same time as Japan. VIZ / Shonen Jump is the best-value subscription for Jump back catalog. BookWalker is for buying volumes to own. Azuki and Manga UP! round out subscription reading from other publishers. Every app below is an official publisher service; links are plain links — none of these services pays us anything.
MANGA Plus by SHUEISHA — best free option
From the publisher of One Piece and Jujutsu Kaisen: MANGA Plus releases new chapters simultaneously with Japan. For ongoing series, the first chapters and the latest chapters are free, and many series can be read through once in the app; a paid tier (MANGA Plus MAX) widens access. If you follow current Shueisha series, this app is not optional — it is the source everyone else waits on. (Not available in Japan, China and Korea.)
VIZ / Shonen Jump — best subscription value
The Shonen Jump service from VIZ opens a huge English back catalog of Jump series for one low subscription, and VIZ Manga covers the publisher’s wider range (including shojo and seinen lines). If your taste is Jump-heavy, nothing legal comes close on price per chapter.
BookWalker — best for owning volumes
BookWalker (KADOKAWA’s store) sells individual manga and light-novel volumes to own, with frequent sales and a solid reader. It is the legal answer to “I want this series on my shelf, digitally” — and the purchases pair naturally with a reading app for the series you follow weekly.
Azuki and Manga UP! — more publishers, more catalog
- Azuki (from Kana) mixes subscription reading with volume purchases, leaning into curated and indie-leaning catalog.
- Manga UP! is Square Enix’s official app — the home of series like Soul Eater and Black Butler in English, with its own chapter-unlock system.
How these fit with Mihon
Legal apps and Mihon are complements, not rivals: official apps for the licensed series they carry (they fund the creators), Mihon for your local files, your server, and everything else in one tracked library. The full comparison is in Mihon vs official manga apps. One warning from experience: no official service has a Mihon “official extension” — any extension claiming an official partnership is a third-party scraper, whatever it calls itself.
