Rok - Rock Identifier

I created Rok because I was tired of coming back from hikes with pockets full of cool rocks and no idea what they were. Flipping through heavy field guides was tedious, and most geology apps were either too technical or just didn't work well. I wanted something simple: point your camera at a rock, get an answer instantly.
Technical details
Framework: Flutter AI Integration: OpenAI API (for advanced image recognition and rock identification) Backend & Database: Firebase (for user authentication, cloud storage, and collection syncing) Offline Functionality: Local caching and on-device storage for previously identified rocks

Main functionality

AI-Powered Rock Identification: Users simply take a photo of any rock, mineral, or gemstone, and the app uses advanced AI to instantly identify it with detailed information including name, type, hardness scale rating, and geological origin.
Detailed Information Pages: Each identified rock includes comprehensive details such as mineral composition, formation process, hardness on the Mohs scale, typical locations where it's found, and interesting geological facts.
Beginner-Friendly Interface: The app is designed for all experience levels, from curious children picking up their first stones to experienced geologists conducting field research.
Growing Database: The identification system continuously improves and expands its knowledge of rocks, minerals, and gemstones to provide increasingly accurate results.

Growth & future plans

Currently, I'm running A/B tests on App Store screenshots to get the highest conversion rate(view to download rate) possible.
