Rushi (如是) is a quiet iPhone & iPad app for reading the Diamond Sutra and Heart Sutra, working a 108-bead mala, copying scripture, and sitting with meditation soundscapes. Everything stays on your device — no account, no analytics, no third-party trackers.

The name 如是 ("Thusness", tathatā) is the first phrase of the Diamond Sutra: 如是我闻 — "Thus have I heard." It is the stance the app tries to embody: read what is here, count what is here, breathe where you are.

🌟 Design philosophy

Quiet by design — no streaks, no badges, no nudges. Each feature is shaped around a single complete sitting.
Faithful to the source — every passage carries translator, source edition, date, and copyright provenance. Two Chinese translations (Kumārajīva and Xuanzang) are both included for comparison.
Truly local — no account, no cloud upload, no analytics SDK. The current version stores everything inside the app sandbox; uninstalling the app removes all data.

✨ Features

📖 Read — Diamond Sutra (Kumārajīva 5 c. + Xuanzang 7 c. Chinese) and Heart Sutra in calligraphic serif typography. 17 UI languages, 9 sutra translations, every passage annotated.
📿 Mala beads — Realistic wood, jade, bodhi, and silver beads you can string and finish with a pendant. Tap to count; 108 beads complete one dedication. The current sutra passage scrolls quietly behind the strand.
🖋 Copy practice — A clean grid-based canvas with stylus and touch support. The original text fades in as a guide; trace one character at a time and save the finished sheet.
🎵 Meditation sounds — Wooden fish, singing bowl, bell, hand bell, rain, bamboo grove. Each loop is seamless and freely layerable. No network required.
🪷 Dedication & history — After each completed mala, write a short intention. Stored on-device, sorted by date and sutra, visible only to you.
🔒 On-device only — No sign-up, no cloud sync to us, no analytics. Apple App Store privacy label: "Data Not Collected."

📜 Open-source scriptures

Every sutra passage shipped with the app comes from a verified public-domain source edition. The cleaned-up Markdown corpus is released here under CC0 1.0 Public Domain Dedication.

🔤 Bundled fonts

The app bundles a glyph subset of Noto Serif CJK SC / TC so that Chinese serif renders reliably even on iOS Simulator runtimes that have stripped Songti / PingFang. Font is licensed under the SIL Open Font License 1.1; the OFL LICENSE file ships inside the app bundle.

🛠 Tech notes

The iOS app is built in Swift 5 / SwiftUI on iOS 17 with SwiftData for local storage, CoreText for sutra typography (custom Chinese serif fallback that bypasses the iOS 17 UIFont(name:) bug via CTFontCreateWithName), and CoreMotion for the gentle pendant-swing physics. The Swift source is not yet open-sourced; this repository contains only the public website and scripture corpus.
