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.
51.5% community return rate - more than half of visitors came back at least twice
3× more app opens for community users vs. non-community users

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.
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.
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 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.
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.
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.
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.
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.
Coin ID grew a multilingual in-app community that now drives 3× more app opens with Octopus Community.
Every coin in the Coin ID catalog is linked to a dedicated community discussion thread via Octopus's bridge post feature. When a user identifies a coin, they can immediately see and join the ongoing community conversation about it - its history, rarity, valuation debates, collector stories.
Coin ID tracked community users vs. non-community users across all months since launch. The gap has been consistent: community users open the app 3× more often than those without access.
Collecting is inherently social - sharing finds, debating valuations, identifying rare pieces, buying and selling. Before the community, all of this happened on Reddit and Facebook groups, outside the app. Coin ID's bridge post feature (linking each catalog coin to a community thread) makes the community feel native to the core experience rather than a separate feature, which drives stronger activation and retention.
Polls have emerged as the highest-engagement format. They work naturally for coin collectors: a quick valuation vote or an identification challenge invites instant, opinionated participation without requiring a full post.
Octopus provides AI-powered content moderation that AIBY configured for its community standards - no dedicated moderation team required. The 6-language setup with instant translation means moderation works across all language groups from a single admin dashboard, without engineering involvement.
Building a full social community internally - feed design, moderation at scale, multilingual support, notifications, backend infrastructure - would have taken months, technical and product resources and heavy technical and human costs to maintain. Octopus delivered all of this in days, with features like moderation, instant translation and conversation on every coin that would have been non-trivial to build. For a company focused on niche consumer apps, the calculus was clear: Octopus offered better capabilities, faster, at a fraction of the cost and risk.
