We go deep where the engineering is hard — companion apps for connected devices, from heating and access control to sleep tech and wearables, down to the raw BLE and Wi-Fi protocol. The app, the backend behind it, and a team that stays. Nordic-grade quality, Sarajevo cost.
We don't do everything. We go deep where the engineering is hard and the trust bar is high.
BLE pairing, OTA and real-time control for connected hardware — smart beds, boilers, printers, wearables.
Key management and UX where security can't slip.
Feeds, real-time messaging and engagement loops that scale.
Web, mobile and backend in sync.
Live data from smart watches, workouts and challenges.
We’re educated engineers with years in the industry, most of us building together for the better part of a decade. Engineering judgment guides every decision; AI is a tool we use, never the thing steering the ship. We work agile and slot into your team — and because our partners’ information matters, safety and security are first-class here, never an afterthought.
Inherit an AI-built prototype and turn it into a production system.
Clean up the architecture, security and tech debt AI introduced early on.
CI/CD, testing and review around AI-assisted code — speed without losing stability.
Most partners come to us with an idea, a prototype that stalled, or hardware waiting for its app. Pick the phase you’re in — each one builds on the last, and we can take it all the way.
We prove the risky part first — the BLE pairing, the ML model, the integration no one’s sure of — in a focused prototype, before you commit real budget.
The lean, shippable product your users actually touch. A native or Flutter app plus the backend behind it — built to launch and learn, not to throw away.
We stay on as your product team: new features, migrations, performance and long-term store support, as the product grows into a platform.
No fixed packages. We meet the product where it is — and most engagements grow from one phase to the next.
Our six most recent builds — across IoT and hardware, fitness, content and consumer platforms.
A wallet-controlled device prints Stable Notes — physical certificates carrying a new wallet's keys, with the private key wiped after printing for offline, non-custodial ownership. The companion wallet stores, moves and redeems, with stablecoin rails via providers like Gnosis Pay.
Sarajevo's city-guide app and web — what to see, do and eat. A full new build is underway: AI chatbot, faster performance and a complete rebrand.
A fitness app pulling live data from Apple and Samsung watches — steps and the athlete's state — with nutrition plans, no-equipment workouts and recurring challenges featuring real public figures. Built for speed and a light interface.
We were part of the team behind Klix.ba's mobile app — one of Bosnia's biggest news brands — keeping day-to-day stability and crash-rate in check and shipping features like reels, ads and AI-assisted news reading.
A community app for truck drivers across Europe — it handled 300+ SOS calls in its first three months and today works as a social network where drivers meet and connect.
A social platform where well-known US artists go live, build communities and raise money for good — live streaming and donations at its core. Delivered by an experienced crew of designers and engineers, in collaboration with Bay Area Coders.
Two native apps — iOS and Android — on a large WordPress-based API layer, fronted by a load balancer, caching and multiple instances to serve a very large audience (~500k active, 50k+ daily). Over several years we ran multiple migration and re-write phases, moving the stack onto new services without disruption.
Mobile control for garage doors and home gadgets, built for a long-established US manufacturer — the app pairs with the door hardware and drives open/close and device state over its connectivity layer.
Mobile capture plus AI analysis of a horse's movement and condition, with diagnostics that surface potential problems early.
A smart-parking app that became a market sensation, and a self-storage product that unlocks and controls personal storage from a phone — the same IoT-access DNA as our garage-door work.
Discovery of restaurants and experiences with native iOS and Android booking — currently in pilot, building toward launch.
Same time zone, the same faces for years, and depth in the domains most shops avoid.
±1h from Europe — real-time collaboration, and visits from time to time are no problem.
The same core team for 7 years — not anonymous resources.
IoT, crypto and security where most shops won’t go — down to how a signal travels, packet by packet, across the network layer.
Your success is our success — a working product is the win we’re after, and what earns the next project together.
15+ engineers, the same core team for 7 years. The people who pitch are the people who build — and you'll meet the leads you'll actually talk to.
A few words from partners we've built with.
I'd recommend AppDelegate for mobile app development. A highly skilled team, flexible setups to fit our needs, at a competitive price — a reliable, flexible partner. They have my vote.
AppDelegate built new features in a global e-commerce iOS app and supported several marketing initiatives. The work was well received and consistently praised — real enthusiasm on all sides to keep collaborating.
Bay Area Coders engaged AppDelegate on several projects needing extra engineering for digital products for our US customers. Their team, experience and culture were a great fit. I recommend them wholeheartedly.
