Appfium is an independent mobile app studio. We've launched 4 of our own apps on the App Store and Google Play — and we bring the same end-to-end craft to building apps for our clients.
Published on the App Store & Google Play
Four apps we designed, built, and shipped in-house — across music, culture, education, and finance. Localized for a global audience and polished to App Store standards.
Shelfify helps vinyl, CD, and cassette collectors organize their collection the way it actually lives — on real shelves, in real rooms — so any record is one tap away. Visual drag-and-drop shelves, Discogs sync, Last.fm scrobbling, barcode scanning, fully offline.
Connect with 2,000+ years of Persian heritage. Convert between Imperial (Shahenshahi), Solar Hijri, and Gregorian calendars with 900+ events and iOS/Android widgets.
Complete BAMF exam preparation with all 310 official questions, state-specific variants for every German federal state, AI explanations, and audio mode.
Track Iranian Rial, global currencies, gold, and 50+ cryptocurrencies in real time. Portfolio, converter, interactive charts, iOS widgets — private, offline-capable, free.
Two things, done end-to-end
We design, build, launch, and maintain mobile apps and the marketing sites that support them — the same capabilities we use on our own products, available to yours.
iOS & Android apps and MVPs, launched end-to-end.
Fast, modern sites built for SEO and conversion.
An independent mobile app studio
Appfium UG is a Germany-based mobile studio. We design, build, and publish our own apps — and partner with founders and teams who need the same product-minded engineering for theirs.
Our in-house portfolio spans German citizenship exam prep, real-time finance data, vinyl collection management, and Persian cultural heritage. Every app is shipped end-to-end by a small, senior team — from architecture and design to App Store launch and maintenance.
Four products live on the App Store and Google Play. We eat our own cooking — every recommendation comes from production experience.
We deliver production-grade apps: robust offline behavior, GDPR-ready data handling, and App Store / Play Store approvals on the first submission.
Our founder brings over 20 years of software engineering experience and more than 10 years focused on iOS and Android. Appfium UG was founded in 2025 to bring that depth to clients and in-house products.
React Native, Swift, Kotlin, TypeScript. We pick the right tool for each product — no framework zealotry.
