Three thousand years ago, Zarathustra folded a whole ethic into three words: good thoughts, good words, good deeds. Pendar-e Nik asks you for all three, once a day. Write one good thought you kept, one good word you spoke, one good deed your hands did — and keep a sacred fire alight. THE FIRE A hand-drawn Persian fire temple, alive at sixty frames a second. The flame burns exactly as brightly as today is tended: a banked, smoking ember when nothing has been offered, a full blaze when the triad is complete. Offer a spark and the fire leaps to greet it. THE LONG TENDING Your streak furnishes the temple. Seven days hangs two oil lamps in the arch. Thirty days unrolls a carpet down the steps. A hundred raises twin banners. Today can stay pending until midnight — the fire dims but doesn't go out while you're still tending. Miss a whole day and the flame starts over; your ledger keeps every word you ever offered. THE TEACHINGS Sixteen short pages open as you practice — Zarathustra and the Gathas, Asha and the Lie, the Chinvat Bridge, the Faravahar, the fire temple at Yazd whose flame has burned since about 470 AD. Real verses in transliterated Avestan, an eighteen-term glossary, one gentle recall question a day, and the whole tradition down one gold thread. THE FIRES OF THE YEAR On Jashn-e Sadeh the walls warm and sparks shower. On Chaharshanbe Suri the little jumping-fires appear on the steps. At Nowruz, blossom drifts through the arch. The app keeps the festivals, and tells you their stories. NEW — THE TEMPLE, ON APPLE VISION PRO The fire steps out of the screen. Stand in the courtyard at Yazd at dusk, among cypresses and lamplight, with the still pool holding the temple upside down. Walk in, and the hall is lit by one flame in a sacred urn, behind glass, as it is in Yazd. It is the same fire. The same streak, the same ledger, the same three offerings — tended on your iPhone in the morning and standing before it in the evening. Build the temple you want: a sculpted Yazd facade or the drawn one, sculpted cypresses, lamp posts, a carved pool basin, and the Yazd Sacred Fire Urn to hold the flame. Set how dark the courtyard and the hall are kept — a room at midnight and a room at noon are not the same room. The fire alone never dims: it answers to your tending, and to nothing else. And Pirooz sits by the water. Reach out and he purrs — his own voice, recorded. ALWAYS IN VIEW Home-screen and lock-screen widgets drawn by the same painter — never the same flame twice, rolling over exactly at midnight. "Offer a good deed in Pendar-e Nik" works from Siri and the Action button. The optional evening reminder is sent only while the day's triad is unfinished — a tended fire stays quiet. YOUR WORDS STAY YOURS No accounts, no analytics, no ads, no tracking. Your ledger lives on your device and syncs through your own private iCloud — iPhone, iPad and Apple Vision Pro, one fire between them. We run no servers and can read nothing. Every feature is free, and will stay free. If the fire warms you, there's a sandalwood tip jar — it feeds the keeper, and unlocks nothing. That's the point. Good thoughts. Good words. Good deeds. Again tomorrow.
