My Sky Labs — Swift astronomy app - Sell Project

My Sky Labs is a live iOS astronomy product: a native Swift eclipse engine, the App Store app, and a website that runs the same engine. The engine is original Swift, written for the phone. It is not a wrapper around Astronomy Engine or Swiss Ephemeris. Eight modules, 78 Swift files: ephemeris, duration, hybrid detector, Full Espenak, topography, path, and contacts. Physics only. No heuristic type fixes. It already runs on iPhone and iPad (App Store, MyskyLabs, version 1.3.0) and on the website API. Catalog search stays fast on the device. Full Espenak polish is on demand. NASA Five Millennium Canon (Espenak), years 1–2999: 14,360 / 14,360 events. Full Espenak type agreement: 0 mismatches. Solar duration median 0.39 s. Lunar duration median 1.99 s. Lunar magnitude median 0.00018. Hybrid detector: all 295 / 295 NASA hybrids, zero misses, zero extras. Astronomy Engine 2.1.19 labels all 295 as Total. Swiss Ephemeris Full labels 277 / 295 as hybrid. Before the common era (−1999 to 0): 9,595 / 9,597 found. Full leaves 10 limb-type residuals. Two penumbral grazes were not patched with a heuristic. Self-contained Espenak–Meeus ΔT matches the canon DT column to 0.591 s max. The app includes a map, any date and time, 2D/3D Moon with libration and terminator, AR, 7 themes, widgets, and 10 in-app languages (its own language system, not the Apple system locale). Freemium: Pro monthly $2.99, annual $19.99, lifetime $34.99. Eclipse search ±5 years is free. Included: iOS source, engine, website, Instagram and TikTok @myskylabs. Engine source is transferred with the sale, not published in this listing. App Store: https://apps.apple.com/app/myskylabs/id6776294476Website: https://mysky.hearth.dpdns.org/
