Universe DMs, Co–⁠Star, The Pattern, Nebula, Sanctuary and Moonly

Six astrology apps that look alike in the App Store and work quite differently underneath. This is what each one does, what it costs, and who it suits, from each company's own listing and help pages.

Which one suits you

If you want to talk to a person, Nebula and Sanctuary connect you with live readers, charged by the minute. If friends and compatibility matter most, Co–Star and The Pattern have the most there. Moonly is the one for Vedic astrology and following the Moon.

Universe DMs is for a few personal messages a day, calculated from your own chart, with the working shown.

What Universe DMs does differently

Every message starts from a calculation: your chart from NASA/JPL's DE440s ephemeris, and the transits to it that day. A measured image of the Sun from NASA's Solar Dynamics Observatory picks the day's theme, and your message is written from exactly those facts.

Tap any message to see what shaped it: your sky next to today's and the real image of the Sun behind the draw. If you shake to ask, the question stays in your head and nothing is recorded.

Where the others do more

Universe DMs is iPhone only, in English and Polish. All five others are also on Android, and Nebula and Moonly come in many more languages. There are no live readers in Universe DMs, and friends, compatibility and tarot are still being built.

Questions worth asking before you pay

How are the readings made, and from what? Is anything charged by the minute? Does the app need your exact birth time, and what does it do without it? What does it ask to access, such as your contacts? Each App Store listing answers the last one under App Privacy.

Questions

Which astrology app is the most accurate?

No app can prove its predictions. What you can compare is how the chart is calculated: the data source, the house system and how an unknown birth time is handled. Universe DMs publishes all three.

Is Universe DMs on Android?

No. It runs on iPhone.

Which of these apps have live astrologers?

Nebula and Sanctuary, charged per minute. Universe DMs, Co–Star, The Pattern and Moonly don't have live readers.
