RahuKaal keeps your daily practice on time. It calculates Rahu Kaal and the four Sandhyas from the real position of the sun at your exact location, rings a proper alarm when each window opens, and shows a full Drik (observational) Panchang for any day — all on your device, with nothing sent anywhere. RAHU KAAL & THE FOUR SANDHYAS See today's Rahu Kaal at a glance, plus Pratah, Madhyahna, Sayam and the night Sandhya — each computed from sunrise and sunset where you actually are, not a fixed table. A live timeline shows where "now" sits in the day. ALARMS THAT ACTUALLY REACH YOU Set an alarm for any Sandhya and RahuKaal rings it like a real alarm — breaking through silent mode and Focus — so your practice doesn't depend on watching the clock. Snooze or stop it right from the Lock Screen. Choose a temple bell, conch, om chant, or chime. A COMPLETE DRIK PANCHANG A dedicated Panchang tab gives you tithi and paksha, nakshatra, yoga and karana — each with the time it ends — plus the Amanta and Purnimanta month and the Vikram and Shaka samvat. Ekadashi and Bhadra (Vishti) windows are flagged so you always know what kind of day it is. DURGA PAATH DAYS Krishna Ashtami and Krishna Chaturdashi are marked as Durga Paath days: the whole app turns to a deep red, a reminder arrives the evening before, and you can look ahead to find the next one. WIDGETS, LOCK SCREEN & LIVE ACTIVITY Home Screen and Lock Screen widgets show the current window and today's tithi at a glance. When a window is running, a Live Activity and Dynamic Island tell you exactly when it ends — in the timezone of the place you're tracking. KNOWS WHERE YOU ARE Pick any city, or turn on "Use GPS" and RahuKaal quietly keeps up as you travel — and always tells you when it does. Times render in the location's own timezone, so Kashi always reads as Kashi time even if your phone is set elsewhere. SYNC TO YOUR CALENDAR Write your Sandhya and Rahu Kaal windows into any calendar you choose, and re-sync cleanly whenever your day or place changes. SHARE THE DAY Tap to create a beautiful devotional card with the day's Panchang and times, ready to send to family. PRIVATE BY DESIGN Your location is used only for the maths, on your device, and is never uploaded. There are no accounts, no ads, no trackers, and no analytics. Namonarayan. MADE FOR IPHONE DUO On iPhone Duo's large display, Home and Panchang open into two columns, and when it's half-folded each column stays clear of the fold. Every iPhone also works in landscape. Available in English and Hindi. Designed for iOS 26.

Verdict
The clearest difference is in-app purchases: Rahukaal at none against KalaDarshini's 6. Rahukaal also leads on ads (none vs shown). KalaDarshini's advantage is update cadence (every 3 days vs every 5 weeks) and iOS requirement (16.4 vs 26.0). On price, review sentiment and device support there is nothing between them.
