Apptellio, LLC builds polished mobile apps, developer tools, and custom software solutions — built for performance, designed for real people.
From concept to launch, we craft software that solves real problems and scales with your goals.
Native SwiftUI apps built with modern architecture (MVVM), clean code, and an eye for user experience that keeps people coming back.
Fast, responsive web applications using modern frameworks. From landing pages to full-stack platforms — built right the first time.
Custom tooling, SDKs, and REST APIs that supercharge developer workflows and integrate seamlessly into your existing stack.
Expert review of your existing codebase with actionable recommendations. We help teams write cleaner, more maintainable software.
Interfaces that are intuitive, beautiful, and purposeful. We design with the end user in mind at every step of the process.
Strategic technical guidance for startups and small businesses navigating critical software decisions and product direction.
We keep things lean and transparent — no surprises, just steady progress toward your goal.
We learn about your product, goals, timeline, and constraints. No cost, no commitment — just a focused conversation to see if we're a fit.
We define the scope clearly, set milestones, and deliver a transparent proposal with fixed pricing — so you always know what to expect.
We build iteratively with regular check-ins. You'll see real progress every week, not just updates about progress.
We handle deployment and remain available post-launch. Your success doesn't end at delivery — it starts there.
We're a lean, senior-level team — no juniors, no hand-offs, no fluff.
Every line of code is written by experienced engineers. No outsourcing, no training wheels on your project.
We focus on iOS and modern web — not everything for everyone. Deep expertise beats shallow generalism.
You talk directly to the person building your product. No account managers or translation layers.
We build software that's easy to maintain and extend — not just software that ships fast and breaks later.
