Siderius and questions
Who is Siderius?
Your AI astrologer: how many questions each plan includes, how Steps become questions, and how packs work.
Siderius is the AI astrologer inside FMRX. You ask a question in chat and get a reading grounded in your own chart and the season you're in, not a horoscope written for everyone born in the same month. It's built safety-first: it gives you context and reflects things back, and it doesn't make decisions for you.
How many questions you get
Each plan includes a recurring allowance:
- Basic (free): 1 question every 3 days.
- Premium: 1 reading every 18 hours.
- Premium Plus: 3 readings a day. The count resets at midnight UTC.
See Plans and pricing for everything else each plan includes.
Turning Steps into questions
You can convert Steps into Siderius questions in the app: 108 Steps buys one question. The walking you do in the journal also buys you time with Siderius. See Steps and Discovery Markers for how Steps are earned.
Question packs
If you want more than your plan includes, you can buy a question pack in the iPhone app or on the web at app.fmrx.ai: 5 questions for $2.99, 12 for $4.99, or 30 for $9.99 (US prices). A pack is a one-time purchase, not a subscription, and the questions never expire. Packs are credited to your account, not your device, so a pack bought on your iPhone works on the web and the other way round.
Packs bought in the iPhone app are billed by Apple, so refunds for them go through Apple. Packs bought on the web are billed by Stripe. See Subscriptions and billing.
