Rahu tells you, in one glance, whether now is a good time to act — using the Vedic Choghadiya system refined over 5,000 years and applied through exact mathematics. No menus. No Sanskrit. No learning curve. Three answers: YES, WAIT, OK. ——————————— WHAT IT DOES ——————————— Every day is divided into 16 periods (8 day + 8 night), each ruled by a planet with its own character. Rahu overlays the inauspicious Rahu Kalam shadow period — the single most important window to avoid for new beginnings. Rahu crunches sunrise, sunset, and planetary math for your exact location, then shows the answer on one screen with a live countdown. ——————————— FREE ——————————— • Main screen — YES / WAIT / OK in real time • Small Home Screen widget • Morning briefing push • Rahu Kalam alert 10 min before it starts • Offline mode — cached until end of day • Languages: English, Russian, Hindi ——————————— PRO ——————————— Unlock the full picture with a 7-day free trial: • Tomorrow — full schedule for the next day with favorability score • Week — 7-day overview with Best Day and Heaviest Day highlighted • Medium widget — current + next 3 periods • Large widget — hero status + upcoming timeline with explanations • Lock Screen widgets — circular, rectangular, and inline • Apple Watch app + 4 complications — glance at your wrist • Live Activity — Lock Screen banner and Dynamic Island countdown • Ask Siri "Is now a good time?" — spoken answer without opening the app • Per-period push — a heads-up 10 min before every transition • (Coming) Widget color themes $2.99/month or $19.99/year — cancel anytime. ——————————— WHAT IT'S NOT ——————————— Not fortune-telling. Not horoscopes. Not daily predictions. Rahu is a timing tool. It computes auspicious windows from astronomical data (sunrise, sunset, planetary rulership) exactly the way traditional pandits do — but without the astrology app bloat. ——————————— PRIVACY ——————————— Your location stays on your device. No tracking across apps. No IDFA. No ads. Read our full policy at akaalius.github.io/rahu-web/privacy.html ——————————— SUBSCRIPTION ——————————— Rahu Pro is an auto-renewable subscription. Two plans: • Rahu Pro Monthly — 1 month, $2.99 per month, billed monthly. • Rahu Pro Yearly — 1 year, $19.99 per year (about $1.67 / month), billed yearly. Both plans start with a 7-day free trial. Payment is charged to your Apple ID at confirmation. Subscription auto-renews unless cancelled at least 24 hours before the end of the current period.

Verdict
The clearest difference is in-app purchases: Luna Sync at none against Rahu's 2. Rahu's advantage is update cadence (every 2 days vs every 2 weeks). On price, ads, device support and iOS requirement there is nothing between them.
