The best hours of your day, read from your chart. Sumuhurta answers one question — when today is good for you — and answers it as one screen. The screen is the sky. It moves from dawn through noon to dusk and true dark, and your windows sit in it as spans of light: one to three in each sunrise-to-sunrise cycle. You may know your chart from apps that read your personality. Sumuhurta reads the other thing a chart holds — time. In this app, the chart is one input to a traditional timing calculation. Sumuhurta reads choghadiya, hora and the abhijit muhurta against your dasha period, the Moon's position relative to yours, the hour's ruling planet and how it sits for you. Each window carries a plain name. A clear run is long and sustained, for the deep work. Sharp is short and bright, for sending and deciding. Steady is even, for meetings and slower work. Beneath the name, a quiet attribution — Jupiter hora · Amrit — is there for readers who know Jyotish. The day runs sunrise to sunrise. If your free hours begin at nine at night, your windows do too. Every personal window Sumuhurta surfaces is calculated to avoid Rahu Kaal, Yamaganda, Gulika, and the Kaal, Rog and Udveg choghadiya periods. It does not display negative-period tables or claim to perform a complete electional-muhurta assessment. It keeps its selected personal windows and leaves the rest as open sky. That is the whole idea, and it is on purpose. Everything is computed on your phone. Your birth details never leave it. No account, no email, no sign-in, no advertising, and no analytics SDK. The developer does not collect data from the app. One price, once. Two weeks free first, full product, no card required. After the trial, the app screen — every window, day and night, the scrub, the share card — stays free forever. The purchase is Sumuhurta arriving on its own: six widget families, StandBy, window-open alerts, an optional 9pm preview when tonight holds nothing further, and a Live Activity that keeps the open window on your Lock Screen and in the Dynamic Island until it closes. You can also choose to show meetings as faint marks on the day line; Calendar access is requested only when you turn that setting on, and event start and end times are read on your phone. No subscription and no add-ons. The paywall displays the App Store's localized price. Sumuhurta is tradition and guidance, not prediction. It does not read your future, match your compatibility, or explain your personality. It offers selected personal timing windows, and it is made to be worth looking at.
