01 who we are

We spent a decade on your side of the table — unclear timelines, hidden costs, developers who vanish mid-project. In 2021 we built the agency we wished existed.

Increment Loop is a senior mobile engineering studio based in Serbia, shipping for startups and enterprises across Europe and the US. European work culture, real timezone overlap, zero hand-waving.

02 what we do

Everything a mobile product needs. Nothing it doesn't.

01

Mobile App Development

Native iOS in Swift, native Android in Kotlin, or cross-platform Flutter — we pick the right tool for your product, not our preference. Consumer apps, enterprise solutions and IoT integrations, handled from first concept through App Store approval and every update after.

  • Swift
  • Kotlin
  • Flutter
  • React Native
02

Complete Mobile Ecosystems

Great apps need great infrastructure. Scalable backends that handle millions of requests, admin panels your team actually enjoys, REST & GraphQL APIs, real-time features — everything needed to run a mobile business, not just launch one.

  • Node.js
  • TypeScript
  • Firebase
  • GraphQL
  • PostgreSQL
03

European Nearshore Teams

Senior iOS, Android and Flutter engineers who work as an extension of your team — same hours, same tools, same care for your codebase. Based in Serbia, we overlap 6–8 hours with Western Europe and the US East Coast. Real-time, not overnight.

  • Team extension
  • Staff augmentation
  • EU timezone
04

Quality Assurance & Testing

Automated testing plus thorough manual passes on real devices. Edge cases, accessibility, performance under load — QA is baked into every sprint, never bolted on. Your users never meet the bugs we catch first.

  • Unit & integration
  • UI automation
  • Real devices
05

Technical Leadership & Consulting

Your fractional CTO for discovery and planning. Native or cross-platform? Which backend scales for your case? How do you survive 10× growth? Answers grounded in a decade of shipping — not theory.

  • Architecture
  • Tech selection
  • Roadmapping

04 how we work

One loop. Five phases. Infinite increments.

discover design build test ship 01 discover
01

Discover

We map your product, users and constraints before a single line is written. Workshops, technical audits, honest feasibility calls — the questions that save months later.

02

Design

Architecture and UX decided together. We prototype the risky parts first, choose the stack that fits your case, and commit to a roadmap you can actually hold us to.

03

Build

Senior engineers, short sprints, working software every week. You see real builds on real devices from sprint one — no big-bang reveals, no surprises.

04

Test

Automated suites plus manual passes on physical devices, every sprint. Edge cases, accessibility, performance under load — your users never meet the bugs we catch.

05

Ship

Store review, release management, monitoring — then we loop: measure, learn, increment. Most of our partnerships run for years, not launches.

05 what partners say
“When we needed to scale fast for a critical launch, their team integrated seamlessly with ours. They feel less like vendors and more like an extension of our own team.”
Cornelius Von Rantzau
Cornelius Von Rantzau Co-Founder & CEO, Yuno
“Their iOS expertise and clear commitment to quality exceeded our expectations. The communication was exceptional throughout — collaboration was effortless.”
Patrick Stammbach
Patrick Stammbach Director R&D, Leica Geosystems (Hexagon)
“One goal: App Store in six months. They delivered on time, the release grew our customer base significantly, and the app ran with zero downtime.”

06 common questions

Questions, answered.

01

What does Increment Loop specialize in?

Native iOS development in Swift, native Android in Kotlin, and cross-platform Flutter apps — plus the infrastructure around them: scalable backends, admin panels, and IoT integrations over Bluetooth Low Energy, WiFi and NFC. We take mobile products from first concept through App Store release and long-term iteration.

02

Where is the team located and in which time zones do you work?

Increment Loop is based in Serbia, in the EU timezone. We overlap six to eight working hours every day with Western Europe and the US East Coast, and we work with clients worldwide — collaboration happens in real time, not overnight.

03

Do you build apps from scratch or join existing teams?

Both. We built the Happiest Baby SNOO companion app from zero to production, and we embed senior engineers into existing teams for years at a time — our partnership with Yuno has run for six years and helped the product pass five million downloads.

04

How senior is the engineering team?

We only staff senior engineers, with ten-plus years of shipping experience on average. The studio was founded in 2021 by engineers who built mobile products for startups and enterprises including Bosch, Leica Geosystems and Kindred Group.

05

How does a project with you start?

With a discovery conversation about your product, users and constraints. Workshops and a technical audit follow, leading to an architecture, a roadmap and a senior team. We reply to every inquiry within one business day — with engineers, not salespeople.
