Coin ID, a coin identification and valuation app, embedded a fully branded in-app community using Octopus Community's native iOS and Android SDK. In under eight months, over half of community members returned more than once, and community users open the app 3× more often than those without access.

Why Coin ID built a social layer inside a coin identification app
About Coin ID (AIBY)
Coin ID is a mobile application developed by AIBY, a leading American co-founding company that excels in building, acquiring, and operating top-tier consumer apps and gaming businesses on a global scale. The app helps coin collectors identify and value their coins: users photograph a coin, and AI-powered image recognition identifies it, retrieves historical data, and estimates current market value. Available on iOS and Android, Coin ID serves collectors across North America, Europe, and beyond - hobbyist collectors, professional dealers, and weekend treasure-hunters who share a deep passion for numismatics.
The business challenge
Coin collecting is inherently social - collectors discuss finds, debate valuations, and hunt for buying or selling opportunities. Before Octopus, those conversations happened on Reddit, Facebook groups, and niche forums, out of Coin ID's sight and out of its control. Every conversation lost meant lost data, one less reason to open the app, and no way to reach the users who cared most.
The app solved a transactional need - identify a coin, get an answer, leave - but gave users no reason to return daily. Building a social layer in-house would have taken 6-12 months: a feed, moderation at scale, multilingual support, notifications. Coin ID needed a faster path.
How Coin ID launched a fully multilingual in-app community in days
Coin ID integrated Octopus Community's native iOS and Android SDK with SSO, so users can access the community with their existing account - no extra registration. It launched on December 26, 2025, on iOS, with Android following on February 3, 2026, backed by a dedicated onboarding step from day one and a main-tab feature banner added in March 2026.
The integration was structured around the coin-collecting use case from the start:
- Conversation on every coin: each coin in the Coin ID catalog is linked to a dedicated community discussion thread. Users don't just identify a coin, they land in the ongoing conversation about it
- 10 community topics organized by coin type, geography, and collecting interest
- Instant translation across 6 languages: English, Spanish, German, Italian, French, and Quebec French
- Gamification (enabled February 2026): points, levels, and badges rewarding active contributors
From identification tool to daily destination: what the Coin ID in-app community unlocked
Every coin becomes a conversation
Conversation on every coin makes the community feel native, not bolted on. Every coin in the catalog links to its own discussion thread - history, rarity, valuation debates, collector stories - so identifying a coin drops users straight into the conversation about it.
A global collector community, unified across languages
Before Octopus, Coin ID's user base was fragmented by language - a German expert on Roman coins and a Spanish collector hunting rare finds had no shared space. Instant translation across 6 languages removed that barrier, while a 10-topic structure (by coin type, geography, and interest) kept the community organized.
Polls and gamification driving recurring participation
Since enabling Octopus's gamification module in February 2026, Coin ID has used points, levels, and badges to reward active contributors. Polls in particular have become the highest-engagement format - with votes more than doubling in April (+128% vs. March). For coin collectors, polls work naturally: a quick "is this worth more than $500?" or "can you identify this hallmark?" invites instant, opinionated participation and brings users back without requiring them to write a full post.
Community as a competitive differentiator in acquisition
Coin ID doesn't treat the in-app community as a retention feature in isolation. The team has identified community as a key competitive differentiator - one that sets Coin ID apart from other coin identification apps that offer only transactional, AI-driven experiences. In early 2026, Coin ID began exploring how to leverage the community angle in paid acquisition campaigns, recognizing that an embedded social layer is increasingly difficult for competitors to replicate quickly.
From coin lookup to collector home
In eight months, Coin ID went from a transactional utility - identify a coin, leave - to a product with a real social heartbeat. Community users open the app 3× more often, more than half return, and collectors now post, vote, and help each other identify rare pieces inside the app.
Coin ID's bet on community wasn't about adding a feature - it was about changing its relationship with its most passionate users. The poll votes that doubled in a month, the six-language community connecting collectors who couldn't reach each other before: proof that Coin ID became somewhere collectors genuinely want to be.
