Software Process
At Tremend, we follow a strict app-building process based on the agile practices used in 2021.
When working with us, expect our team to follow this 7-step process:
Application development:
the next step in the process of mobile app development includes the actual development of the mobile application. The entire task is completed in a transparent environment, with constant updates and feedback.
Requirement gathering:
the initial stage involves collecting info about your project, brand, and scope of work. This is imperative for understanding your goals and ensuring we’re building an app in sync with your needs.
Creating the UX/UI design:
the first step of the app building process involves creating the actual design of your app, using the latest design tools and procedures. We brainstorm the coolest designs and move beyond the ordinary to make your app look totally unique.
Maintenance & continual support:
after deployment, we continue to stand by your side and provide you with ongoing maintenance and support services.
Quality assurance:
at Tremend, we do not compromise on quality, thus you can gain the peace of mind that your app is 100% bug-free and works like a glove.
Deployment:
at this point, your app is ready to be showcased in the app store.
Prototyping:
once the design is ready, the prototype of the app follows suit, being sent to the development team.
