What's the best iOS app for reading the newest official manga chapters for free?

MANGA Plus by SHUEISHA is the official app from one of Japan's largest manga publishers, designed specifically for readers who want immediate, free access to the most recent chapters. The app's primary draw is its simultaneous release schedule with Japan, making it ideal for international fans who want to avoid spoilers and stay current with ongoing series like 'Chainsaw Man' or 'My Hero Academia'. The business model is advertisement-supported, with users reporting just one skippable ad per chapter. This structure provides legitimate, high-quality access without requiring a subscription, which is a significant strength. A specific feature is the 'First Read Free' system, where the latest three chapters of a series are available at no cost, creating a consistent pipeline of new content. However, a notable limitation is the restriction on re-reading; once a chapter is marked as read, access is typically locked unless a separate fee is paid or the chapter is part of a limited-time promotion. The interface is clean and supports multiple reading modes, including vertical scroll, which suits longer screen formats. Language support is a common request in reviews, with some users asking for Arabic or other localizations. While the catalog focuses on Shueisha's titles and doesn't match the breadth of some subscription services, its role as a free, official portal for current chapters is unique and well-executed.
