iOS app development, led from Valencia

Honestly: hire us for the work, not the city. Our CEO and headquarters are led from Valencia, Spain, with engineering distributed across Ukraine, and most of our real case studies are iOS builds — a live crypto exchange’s trading app, a construction job-costing app, a city-exploration app, and a seizure-alert wearable. Location is where we’re led from; the shipped work is the actual reason to hire us.

Yes — all of it, in practice. Our engineering team is distributed and remote-first, and our real clients are in London (Walkable), Berlin (Mellow), and beyond. A Valencia HQ doesn’t mean a Valencia-only client list.

We don’t keep a public office you can walk into — calls and async work are how every engagement actually runs, wherever you are. If an in-person meeting matters for a specific project, raise it on the first call and we’ll figure out what’s practical.

The same three tiers as any Applefy project: $20K-$40K for a simple app (3-6 weeks), $40K-$100K for a mid-complexity app (2-4 months), and $100K-$250K+ for a complex, multi-feature app (4-8 months). Where a given project lands depends on scope — screen count, backend integration, and platforms beyond iPhone.

Depends on the project. For BitCoinPay we own the iOS client only — the exchange’s backend belongs to the client’s own team. For Kiolfast we built the iOS app, the Android app, and the backend API underneath both. For a new build we can scope the backend alongside the app — see our Backend Development page — or integrate with infrastructure you already have.

Yes. Walkable runs on iPhone and iPad; Mellow pairs iPhone with Apple Watch to detect motion typical of seizures and alert emergency contacts — it doesn’t diagnose, predict, or detect every seizure. We also offer watchOS Development and iPadOS Development as standalone services beyond what a given app needs.
