From concept to App Store:
mobile apps built to scale with you
We design and develop custom mobile apps that fit your business needs and drive growth. From UX to launch and beyond, we build native and cross-platform apps that stay fast, secure and reliable as you scale.
Mobile app development covers everything between an idea and a listing on the App Store and Google Play: product design, the native or cross-platform build, testing, release, and the maintenance after it. Inventiff does all of it in-house — including modernising an existing app and hardening the security of one already shipped.

Our process
Smooth, practical, optimized
Exploring
Before starting a new collaboration, we hold an initial meeting to establish the project requirements and identify potential opportunities. That way, we’ll start with realistic expectations and make sure that everyone involved knows what the project entails.
Discovery phase
Next, we’ll analyze your main competitors from a technical and usability perspective, so we’ll get a better understanding of your target audience and adjust the UX accordingly. Based on the data we gather, we’ll provide cost and timeline estimates.
Prototyping
Now, we can build the prototype for your digital product so you can see how it will look and work. This allows us to make adjustments early in the process and save plenty of time and resources in the long run. We address edge cases, gather feedback, and fine-tune everything before development.
Developing
As soon as the project requirements, functionality, and final design are set in stone, your project enters the development stage. The team uses in-depth technical documentation to make sure that the product meets the highest standards in terms of functionality and performance.
Testing
Both manual and automated quality assurance guarantees your product provides a positive user experience, on every device and every flow.
Launching
We take all the necessary steps to make sure that the product is released successfully, and we keep managing it afterwards.
