Meet Sterium

Bring your spiritual practice, timing, study, and personal grimoire into one place.

Sterium is a spiritual practice companion built around the moving parts of real ritual, study, reflection, and timing. Follow the current moon, Sabbats, planetary day and hour, numerology, transits, correspondences, and lucky hours; generate or build spells and correspondence entries; keep a detailed grimoire; create vision boards; and organize meaningful events without splitting your practice across disconnected tools.

Timing, spellwork, and reflection stay connected.

One Connected Practice

Your spiritual tools make more sense when timing, study, ritual, and reflection can inform one another.

Sterium connects daily spiritual context, correspondences, spells, grimoire entries, vision boards, and events into one personal system. Instead of treating each part of your practice as a separate app or notebook, you can keep the information, inspiration, and timing around your work together.

Daily Spiritual Dashboard

See the spiritual context around today before you begin

Sterium's Home experience can surface the current moon phase and zodiac sign, illumination, moon day, moonrise and moonset, the next Sabbat, planetary day and hour, current correspondences, daily numerology, retrogrades and transits, lucky hours, and working-timing guidance. Home widgets can also be customized so the information you care about most appears first.

Correspondences

Build a reference library that can be generated, edited, or written by hand

Browse correspondence categories, generate entries from a name, save results, edit them later, delete what you no longer need, or create custom entries manually. Sterium's correspondence records can hold practical associations ranging from intentions, planets, zodiac signs, elements, deities, chakras, numerology, Tarot, Sabbats, lunar phases, seasons, days, colors, symbols, ritual uses, folklore, warnings, and category-specific details.

Spells

Generate spellwork from intention, context, and practitioner level

Choose a spell category and intention, set an expertise level, describe the situation and desired outcome, and let Sterium generate a structured spell. You can also add spells manually, browse saved spells by category, edit generated work, replace it with your revisions, and remove spells you no longer want to keep.

Grimoire

Keep many kinds of spiritual records inside one searchable grimoire

Sterium supports journals, working documents, working results, dreams, synchronicities, pathwork, moon-phase entries, deity devotion, divination, meditation, shadow work, manifestation, experiences, and custom grimoire entries. Search across entries, filter by type, build custom filters, and manage custom templates for forms that match the way you personally document your practice.

Vision Boards

Turn inspiration into visual collections that stay inside your practice

Create multiple vision boards, give each one a name and description, collect images into them, and open dedicated board details when you want to work with a collection. Sterium's share extension also lets images arrive directly from places like Pinterest, Safari, Photos, and other sharing sources.

Events

Give meaningful dates and plans a dedicated spiritual calendar

Sterium's Events area uses one shared event store with Agenda, Timeline, and Calendar views. Create new events, open full event details, edit existing entries, and move between high-level calendar planning and date-focused timeline views without maintaining separate copies.

Customizable Practice

Let the app adapt to the way you actually practice instead of forcing one fixed system

Sterium includes customization at several levels: reorder or hide Home widgets, build custom grimoire templates, create custom grimoire filters, add correspondences manually, add spells manually, and choose which parts of the system deserve the most attention in your own practice.

Everything Else

Open each part of the Sterium experience

Moon, Sabbats & Planetary TimingFollow the current lunar cycle and time ritual work more intentionally

Home tracks the current moon phase, zodiac sign, illumination, moon day, moonrise and moonset, the next Sabbat with live countdown, and the planetary day and current planetary hour. Local planetary-hour calculations can use location when available.

Daily Correspondences, Numerology & Sky EventsSee today's symbolic context without assembling it manually

Sterium can surface current planetary, elemental, color, crystal, and herb correspondences alongside daily numerology, Tarot archetype associations, retrogrades, and current astrological transits.

Lucky Hours & Working TimingUse daily timing information to plan spiritual work

Lucky-hour calculations and the working-timing system help surface favorable windows and timing reasons for practice. Saved timing tools let useful results stay available beyond a single calculation.

Custom Grimoire Templates & FiltersDesign entry structures that match the way you document your practice

Beyond Sterium's built-in grimoire types, custom templates let you define your own record structures, while custom filters make it easier to group the entry types that belong together for a particular focus.

Apple ShortcutsPull key daily spiritual information into automations and voice workflows

Sterium exposes App Shortcuts for the current moon, upcoming Sabbat, planetary day and hour, and current correspondences, making core daily information available outside the main app when building shortcuts.

Vision Board SharingSend inspiration into Sterium from other apps

Sterium includes a Share extension so visual inspiration can be sent directly into its vision-board system from external apps instead of requiring a separate import-and-organize step later.

Settings, Release Notes & Report CenterKeep app information, feedback, and support tools inside Sterium

Settings includes release notes and an in-app Report Center with dedicated flows for bug reports, beta feedback, and feature requests, keeping product feedback connected to the app itself.

Built Around a Living Practice

Spiritual work changes from day to day, so the system around it should be able to change too.

Sterium is built around a practice that can include timing, study, ritual, reflection, divination, inspiration, planning, and recordkeeping in different proportions at different times. Each area has its own depth while remaining part of the same connected spiritual workspace.
