Mobipocket Reader Alternatives: Modern eBook Apps to Try TodayMobipocket Reader was once a popular choice for reading and managing eBooks on desktops and early mobile devices. Although development stopped and its formats have largely become legacy, many modern eBook apps now offer richer features, better compatibility, and smoother reading experiences across devices. This article surveys the best Mobipocket Reader alternatives available today, comparing features, formats supported, platform availability, and which users each app suits best.
Why switch from Mobipocket Reader?
Mobipocket’s advantages in its heyday included lightweight performance and support for personal libraries. Today, however, modern readers offer:
- Better format support (EPUB, PDF, AZW3, etc.).
- Cloud sync across devices.
- Advanced reading features: EPUB reflowable text, fonts, themes, reading statistics, and annotations.
- Improved DRM handling and conversions through integrated or companion tools.
- Active development and community support.
If you still have old .mobi or Mobipocket files, conversion tools and many readers can import them; otherwise, consider moving to an app that fits your current devices and reading habits.
Criteria used to evaluate alternatives
I evaluated apps using these factors:
- Platform support (Windows, macOS, Linux, Android, iOS, web).
- File format compatibility (EPUB, MOBI, PDF, AZW3, etc.).
- Library management (tags, collections, metadata editing).
- Syncing and cloud storage options.
- Reading features (themes, fonts, annotations, TTS).
- Extra tools (conversion, store integration, social/notes export).
- Privacy and cost.
