iSutra is an offline sutra reading and practice app. Open a Daily Sutra, compare Chinese and English with optional vernacular notes and pinyin, follow recitation highlighting, trace a line by hand, and dedicate the day. No account, no ads, no tracking. Texts are built in and work without a network. For study and cultural learning only. This is not just a source-text browser. The category is crowded. iSutra puts the difference in bilingual reading, highlighted recitation, woodfish counting, handwritten tracing, daily practice, and a Daily Sutra that reaches you through widgets, Lock Screen, Control Center, and voice shortcuts. It is made for education and cultural study. It does not tell fortunes. Built-in library Browse Prajna, Lotus, Avatamsaka, Pure Land, Ksitigarbha, esoteric mantras, Chan, Forty-two Chapters, and Eight Awakenings. Long works open by section: Diamond in thirty-two parts and Ksitigarbha in thirteen chapters, still offline. Also included: Heart Sutra, Amitabha Sutra, Universal Gate, Platform Sutra, Samantabhadra vows, Medicine Buddha vows, and mantra excerpts. It does not claim to be the whole canon. 1. Daily Sutra: today's text, continue reading, famous lines, local reminders, and shortcuts to recitation, chanting, copy-sutra, practice, study, random, and keyword hunt. A widget can switch it. 2.
