GradFlowLab is an indie app studio building practical AI-powered tools for everyday life. Our flagship app, Jewelry Expert, lets you snap a photo of any gem, ring, necklace, or bracelet and get instant AI analysis — identifying metals, gemstones, hallmarks, style era, condition, and an estimated value range. Built for collectors cataloging inherited or vintage pieces, shoppers verifying purchases, and anyone curious about jewelry they own. Beyond jewelry, we build focused apps that each do one thing well: Markdown Notes for distraction-free writing with live preview and widgets, Buddha AI and Zen Heart for mindfulness and meditation, White Noise Sleep Sounds for better rest, Flash AI Photo for instant ID photos, and SkinLens for AI skin condition identification. All apps are available on iOS and iPadOS, with select apps also on macOS and visionOS. Most are free to download with optional premium features.
