How Pocketstone makes its readings
What the app says about stones, what it does not say, where the mineralogy comes from and which parts of the tradition are a twentieth-century arrangement. This page carries the evidence disclosure and the source notes that used to sit under each stone.
The disclosure, first
Pocketstone is for reflection and everyday routine. The content describes cultural and historical traditions. There is no scientific evidence that crystals affect health, mood or wellbeing. Nothing in the app is advice about any medical matter or a substitute for a professional.
The same sentence sat at the foot of nearly every screen in the app until 30 August 2026. It has not been softened by moving here — it is the same wording, and it governs every reading the app produces.
What a reading actually is
Two things, kept apart on purpose:
- Mineralogy — what the stone is, its species and formula, its crystal system, its hardness, what causes its colour, and how to look after it. This is checkable and it is meant to be checked.
- Cultural history — what people have done with a stone like this, where, and when. Reported as history, not as a mechanism.
The app does not say that a stone acts on your body or on your mind. What a stone is for, here, is a daily reminder you set for yourself. That is the whole claim.
Where the evidence stands: people have used stones like this for a long time, in a lot of places, for a lot of reasons. There is no scientific evidence that a stone changes anything in your body or in your circumstances.
The chakra scheme is a twentieth-century arrangement
The seven-colour chakra scheme the app uses to group stones is a Western arrangement. Classical Indian sources describe chakras and do assign colours to them, but not the rainbow sequence; that mapping was assembled by Western writers between the 1920s and the 1970s. It is used here as a familiar filing system, and it is not presented as ancient. Saying otherwise would be the first false claim in the app, before any stone is named.
About the pictures
Some stones are shown as themselves. The rest show the render for their chakra group, because a few minerals are defined by an optical effect a renderer cannot express — a labradorite that does not flash is not really a picture of labradorite. Where the image is a group stand-in rather than the stone named beside it, the app says so on the screen. Read the picture as decoration and the text as the content.
Where individual stones need a note of their own
Some entries carry an extra line, because the honest thing to say about that stone is not the same as for the others: a name that misleads about what the material is, a trade name of recent invention presented elsewhere as ancient lore, or a stone that is commonly imitated and hard to tell apart. Those notes are appended to the standing framing sentence, never substituted for it.
Where the readings come from
They are written in advance, by people, and reviewed before release. Nothing is generated by a language model while you read, and no reading is written individually for you.
What the app does not do
- It does not claim any physical or psychological effect from a stone.
- It does not give medical advice and is not a substitute for a professional.
- It does not diagnose anything or recommend acting on anything it says.
Sources
Mineralogical data — species, formula, crystal system, Mohs hardness, cause of colour — is taken from standard mineralogical references. The history of the seven-colour chakra scheme is documented in scholarship on Theosophical and later Western writing on the subject. The full source list is kept alongside the app's content and is available on request at hello@infoash.de.
