Coin Identifier - CoinCheck

What it does

CoinCheck is a specialized tool for numismatists and hobbyists. Its primary function is to identify coins using a phone's camera. Users can snap a photo or upload an image to get detailed information about a coin, including its name, origin, year, and estimated market value. Beyond identification, the app serves as a digital collection manager, allowing users to organize their coins into custom sets and track their total value.

Where it shines

CoinCheck shines in its focused and flexible approach to the collector's workflow. The initial onboarding carousel (00:03) uses simple animations to quickly demonstrate the app's core value. The identification process itself is supported by a helpful tutorial (01:14) that guides users on how to take the best photo for accurate results. Perhaps its most powerful feature is the AI Expert chat (02:50), which transforms the app from a simple database into an interactive, knowledgeable resource for deeper questions.

UX highlights

Multi-modal entry: The app allows users to add coins in three ways: photo identification (01:12), database search (04:24), or manual entry (05:15), catering to various user needs and levels of expertise.
Clear photo instructions: Before a user takes a photo, a four-step visual guide (01:14) explains best practices like keeping the coin straight and in focus, proactively reducing user error.
Conversational AI: The AI Expert feature (02:51) provides detailed answers and suggests relevant follow-up questions, creating a guided and educational user experience.
Integrated Social Proof: The paywall (00:28) effectively builds trust by embedding a scrolling carousel of user testimonials directly above the subscription options.
Collection Management: Users can not only save identified coins but also organize them into custom-named sets (02:30), adding a layer of personalization to their digital collection.
Contextual Actions: After identifying a coin, the app presents clear options like checking its value or adding it to a collection, guiding the user to the next logical step.

Monetization & growth

The app uses a free-trial model, presenting a paywall at the end of its onboarding flow (00:28). The paywall is well-designed, featuring a scrolling list of positive user reviews to build credibility. It presents two options: a weekly subscription with a 3-day free trial and a yearly plan that highlights significant savings (00:30), breaking down the cost to a weekly figure to make it seem more affordable. The subscription appears to be required to access the core features of the app.

Who it’s for

This app is clearly designed for coin collectors, from beginners to seasoned experts. Beginners will appreciate the simple photo identification and AI expert for learning. Experienced collectors will value the comprehensive database, detailed information, and the ability to manage and organize a large digital collection. It serves anyone curious about the value or origin of a coin they've found.

Notes & opportunities

The app's core loop is strong, but the user journey could be slightly smoother. For instance, after identifying a coin and viewing its details, adding it to a collection requires creating a new set (02:31) every time, which could be streamlined by allowing users to add to a general 'My Collection' pool first. The initial onboarding also includes a rating prompt (00:19) before the paywall, which feels a bit premature and might interrupt the user's focus on the app's value.
