My initial trepidation in hiring an agency in another time zone, and a market I was not familiar with, proved unfounded. Always professional. Incredibly switched on. I get the sense they actually really understand what we are trying to achieve. I don’t have to explain everything – they intuitively seem to understand. The designs the team have come up with are fantastic.

The Process Of Mobile App Development

Scroll →

01 Technical specifications

The client comes to us with a business idea and a tech task. If there is no technical task, the manager asks the client to fill out a questionnaire. Based on the collected data, a business analyst studies the market and draws up a project plan for DApp development services, for example.

02 Prototype and design

Our UX/UI designer draws up a layout of the future product, deciding on the location of all interface elements and the color scheme for the background, buttons, icons, widgets, and other graphics. The designer creates a screen map or a detailed prototype according to our full guide to mobile-first design.

03 Mobile Development

As soon as the technical task is formed, the layouts are created, and the prototype is approved, the developers begin work on the product. They code the app’s planned behavior and establish its connection with the server. By the way, we know how to create Telegram Mini Apps and how to build a Telegram wallet, not only native mobile apps.

04 Testing

A QA engineer develops a system of manual and automatic tests for each project, such as Papirus. As errors are discovered, developers fix them immediately. Such a strategy reduces the time it takes to finish the project.

How we work

Let’s talk
  • One proficient developer or a skilled team exclusively committed to your project, dedicating their entire working month solely to your endeavor.
  • Assured Payment Terms: Secure your commitment by making a prepayment for the last month’s guaranteed payment.
  • Sprint-Based Payments: Divide the payments for ongoing sprints – 50% at the outset and the remaining 50% at the end of each month.
  • Alternative Approach: Opt for terms with sprint payment spanning 4 weeks – a simple 100% prepayment at the start of each month.
  • Our developer or team focuses solely on the tasks you’ve outlined.
  • Sprint-Driven Pricing: The rate is configured for a two-week sprint, encompassing 80 hours of dedicated developer/team effort.
  • Sprint Start: Begin with a 100% prepayment for a full sprint, ensuring a seamless start.
  • Monthly Hourly Payment: As the month progresses, make payments based on the hours our adept developers spend. Additionally, any agreed-upon overtime tasks (as mentioned in the report) are billed at the established rate.
