Sky Today：逆行追踪器

Yes, Sky Today is free to download and lets you read the live sky right now with no cost. Premium unlocks extras like scrubbing and time-travel across the full year, exact aspect perfection dates, the complete events timeline with countdowns, planet detail with motion trails, and accent colors and display controls.

No. Sky Today shows the transiting sky — where the planets actually are right now — which is the same for everyone on Earth. There's nothing to enter and no account to create; open the app and it works immediately, anywhere in the world.

Sky Today uses a Swiss Ephemeris-grade engine for Western (tropical) astrology, with geocentric positions computed from real astronomical data rather than simplified approximations. That's why retrograde planets actually slow, stop, and reverse as you scrub the timeline through their real stations — it's a live calculation, not an animation loop.

Sky Today is built around live, current-moment data and the scrubbing timeline, so it's designed to run with an internet connection for the freshest positions and event countdowns. If you're planning to check the sky mid-flight or somewhere with no signal, expect it to need connectivity rather than working fully offline.

Yes, it's published on both the Apple App Store and Google Play with the same live-sky feature set on each platform.

No — Sky Today is a precision instrument for the collective sky, not a horoscope feed or personal reading. It shows where every planet from the Sun through Pluto sits right now, along with retrogrades, aspects, and moon phases. It doesn't ask for your birth chart because it isn't generating anything personal to you.

Sky Today is a live, no-birth-data transit viewer — it shows the sky as it is for everyone right now, using Western tropical astrology. Vyom is a full Vedic astrology app that builds your personal Kundli from your exact birth details, with divisional charts, dashas, and matchmaking. If you want to watch retrogrades and aspects happening overhead, Sky Today is the tool; if you want your own chart analyzed, that's Vyom.

Sky Today uses Western (tropical) astrology. If you're looking for a Vedic (sidereal) chart with Lahiri ayanamsha, nakshatras, and dashas, check out Vyom or VedKal instead — both are built around the Vedic system.

It works for both. The live orbit view and moon phase are easy to read at a glance even if you don't know an ephemeris from a horoscope. The aspect wheel, exact orbs, and retrograde station dates give experienced chart-readers the precision they're used to from professional software.
