Point your camera at a stone and Mineralo tells you what it is likely to be, and why it thinks so, describing what it actually saw in your photograph rather than reciting a textbook.

Most stones on most beaches are nondescript, and an app that confidently names every one of them is lying to you. When a specimen has nothing diagnostic about it, Mineralo says so instead of picking the nearest match and dressing it up with a number.
Every identification says what it saw: the banding, the lustre, the way the surface broke. It also says how to check it yourself with a scratch and a streak. An answer you can weigh is worth more than one that is merely fast.
Every find you keep records where you were, so the collection doubles as a map of the places you have been, and you can find your way back to the good spots.
Ranks and badges mark the milestones worth chasing: new species, new places, rarer material. Twenty-two rocks and minerals, each with a reference photograph and the properties that separate it from its lookalikes, browsable whether or not you have found it yet.
Finds, photographs and coordinates live on your phone. Nothing is uploaded, nothing is shared, and there is no account to make. The privacy policy says exactly what leaves the device and why. It is short, and there is not much on the list.
