Primary Technology in App Development

Native app development for iOS is what the company started from – two founders are iOS mobile engineers and it’s our profile & historically the main stack for mobile development.

The native iOS app development team is the largest & oldest one in the company with experience on working on a range of projects starting from simple social media apps ending complex e-learning projects with Unity integration or full-fledged management systems.

Interexy’s Experience in IOS
Native Application Development

Linguix app screenshot


We’re building an AI-powered free writing assistant using native iOS app development solutions. This SaaS product is dedicated to help users eliminate grammar and language mistakes and find the perfect words to express their thoughts.


Our goal — build a smooth, high-quality & stable platform based on an AI-algorithm the service is using currently. The final solution should be not the regular app, but a utility app vastly connected with the user keyboard.


This service is in development for today – we’re finishing some parts of it & polishing the whole product to respond to quality standards. We consider Grammarly as the main competitor.

Service focused on real estate to optimize editing processes and improve the quality of photos


Our team had to create a solution that would meet both business and user needs in the market, where user problems used to be solved in a different way for many years.


This project is focused on real estate to optimize editing processes and improve the quality of photos. Thus, realtors can get great photos for their own use in a short time by pressing just a couple of keys in the application.


The main advantage of this project is the simplicity of its concept. The user simply takes a photo in the application, select the photos that he wants to edit, and enters his email to receive his completed order. After that, he pays for the service and the app automatically uploads the photos to Google Drive. The app may offer additional editing services for an additional cost. After that, the client will receive the photos back by email.

Jason Kelley

Founder @MUSL

“I was always looking at where it intersects with the skill base of the team and the customer service, communication, project management. You can have a really amazing team of talented developers and programmers but you’re going to end up spending a great deal of your time actually trying to self-manage them. Versus you have the opposite which is really good project management and really excellent communication but not so great development team. And what I’ve enjoyed working with Interexy is the fact that I get both of those pieces together and that has been very satisfactory.” Read more

“Within its first nine weeks, the app received 8,000 users and a 4.7-star rating. The platform is well designed and hasn’t had many bugs. Interexy LLC is fast and efficient at building new features as well as taking scope changes in stride. Expertise and responsiveness are hallmarks of their work.” Read more

Will von Behr

Founder @ Urbs Travel

“I got an amazing product that was exactly what I envisioned when I first sat out & drew the plans. The two areas that I think where Stan & his team particularly excel: first is attention to detail (…) & secondly the kind of support they’ve provided after the app was largely complete. I’m sure the number of teams just do the bug work & leave it but they are [Interexy team] always on hand to answer any questions really at any time of day which is incredible.
So I’d encourage anyone who wants to build any sort of product to use Stan & his team. It’ll accelerate your business and make your life a whole lot easier.”
