Sutra — A pocket Tripitaka. An offline, distraction-free reader for the Chinese-Buddhist canon, with text sourced from CBETA (Chinese Buddhist Electronic Texts Association, latest open release), grounded in the Taishō Tripitaka. Translations by Kumārajīva, Xuanzang, Yijing and others — organized for daily reading. ■ 35 scriptures The Dharma-Drum daily-recital selection: Heart Sutra, Diamond Sutra, Amitābha Sutra, Universal Gate of Avalokiteśvara, Samantabhadra's Vows, 42 Sections, Medicine Buddha, Earth Treasury, Śūraṅgama, Perfect Enlightenment … Four major repentance liturgies: Liang Emperor, Threefold Samādhi Water, Great Compassion, Earth Treasury Jeweled, 88 Buddhas, Ten Small Mantras. Oldest-stratum short collections: Dhammapada, Aṭṭhakavagga, Itivuttaka, Saṃyukta-āgama selections (including Pabhassara Sutta, Mahāparinibbāna verse). ■ Four-language parallel reading Four core scriptures carry four reading modes:  Chinese — Classical Chinese translation (Xuanzang, Kumārajīva …)  Sanskrit — IAST + Devanāgarī, the original sound  English — translation, opening the meaning  English→Chinese — modern Mandarin transcribed from the English An in-app "Reading Languages" essay explains why each mode exists. ■ Traditional vertical ↔ modern horizontal One tap to switch. Vertical preserves the handwritten-sutra ritual feel; horizontal suits commuting and night reading. Four font sizes (S/M/L/XL); the size stays put when TTS playback is on. ■ Cinnabar-stamp aesthetic, sprinkled-gold paper Visual identity drawn from Song-Yuan sutra manuscripts: cream cotton-paper texture in light mode, royal navy with sprinkled gold in dark mode. Restrained palette designed to be easy on the eyes during long readings. ■ Recitation TTS Built-in Mandarin voices (Tingting / Meijia / Sinji) read along with you — useful when driving or eyes closed. ■ Six reflective essays  • Textual Strata — what layer of "the Buddha's word" we are reading  • Three Buddhas — the three shapes the Buddha takes in text  • Path of Deification — the five stages from man to god  • "Are all sentient beings originally Buddha?" — tracing the lineage of a Chan koan  • Reading Languages — positioning the four modes  • Sources & Attribution — CBETA license + acknowledgements ■ Reminders Daily passage push at 06:00; 16 major Buddhist holidays (Buddha's bath day, Avalokiteśvara's anniversary, Earth-Treasury Bodhisattva's anniversary …) push at 09:00. Optional integration with the system Reminders app. ■ Privacy Zero data collection. No tracking, no analytics, no upload.
