Rock Identifier is a comprehensive app that allows you to identify rocks, crystals, minerals, and gemstones. You can simply take or upload a photo, and the app will provide an instant identification along with detailed information about the stone.
For each identified stone, the app offers detailed information including its Name, Chemical Formula, Hardness, Colour Variations, and main locations where it can be found. It also provides articles on identifying real versus fake gemstones based on various characteristics.
The app offers a free version with identification capabilities and access to its encyclopedia. However, there is a premium subscription available for unlimited rock identification and an ad-free experience, which includes a 7-day trial.
Beyond identification, the app includes a metal detector to help find lost metal objects, a section on the healing properties of crystals and zodiac stones, and a collection feature to manage your identified stones and create wishlists. It also offers an email service for one-on-one consultations with a rock expert.
This app is ideal for beginner rock hounds looking to identify their discoveries, experienced crystal collectors wanting to expand their knowledge, geology students, and anyone interested in learning more about the stones and minerals around them.
