Frequently asked questions
Is Sideria free?
Yes. Every feature is free. The deepest ones unlock with Karma, which you earn by using the app and inviting your people, never by paying. Sideria was born as an alternative to astrology apps full of ads and misleading tactics to push monthly subscriptions or calls to premium-rate phone lines.
Do I need to install anything?
No. Sideria works in your phone or computer browser, and you can add it to your home screen. The Android and iOS apps are coming soon.
Do I need to know my time of birth?
Not to get started. With your date you already have your sign and your daily reading. Your time and place of birth let us calculate your exact Moon, your Ascendant and your houses.
What is synastry?
It's the comparison of two birth charts. It shows where two people complement each other and where they may clash.
Can I add someone who doesn't use Sideria?
Yes. With their name and date of birth you'll see what the sky holds for them every day. If they join one day, your connection becomes complete.
