Sync centers around one core experience: your daily sync. Each morning between 06:06 and 12:12, you can sync with someone important to you. By linking your birth chart with theirs, Sync generates structured relationship indicators based on both charts. These indicators provide a daily interpretation expressed through scores and explanations. If the window is missed, you cannot access that day’s Sync and must wait until the following day to unlock it again. This design encourages intentional use rather than passive checking. Through this daily process, you receive clear scores along with interpretations and personalized guidance covering attraction, attachment, communication, and tension. These interpretations are designed to help you reflect on your interactions and manage your relationship more thoughtfully on a daily basis. They are not predictions or instructions, but contextual insights meant to support your own decisions. Sync is designed as a relationship tool, not a horoscope service. It helps you reflect on and understand your interactions with someone rather than offering generic predictions. Astrology powers the system behind the scenes. Birth chart data and current planetary cycles are used to generate the analysis, while the experience itself remains centered on relationships and personal awareness. Sync is an insight and entertainment tool and does not provide medical, psychological, legal, or professional advice. Subscription: Sync requires a paid subscription to access the app and its features. All relationship insights and the daily Sync experience are available exclusively to subscribers. Sync offers auto renewing weekly and annual plans. Pricing is shown in the app before purchase and may vary by region.
