is a high-versatility document and eBook reader originally popular on Palm OS and Windows Mobile, now fully optimized for modern Android devices. It is developed by DC & Co. and serves as a powerful reader capable of displaying plain text, Palm Doc, and its native, proprietary iSilo format (.pdb).

The iSilo format is designed for text. If you have massive reference materials—such as a complete medical encyclopedia, a technical manual, or a religious text library—converting them to iSilo format results in significantly smaller file sizes. An Android phone can hold a library of thousands of books in iSilo format that would otherwise consume gigabytes of space in PDF format.

However, as a platform , it is dead. New content cannot be authored on Android, and the UI violates Google’s Material Design guidelines. The paper concludes that iSilo for Android should be regarded as a rather than a productivity application. Future work involves extracting iSilo .PDB files into EPUB via reverse engineering.
