Apps in 15 days: Is it possible?

When we say we can develop a functional app in 15 days, most business owners look at us with skepticism. It's understandable: the software industry has a well-earned reputation for missed deadlines, blown budgets and projects that drag on for months. But there's a different way to work, and at SprintMarkt we've spent over two years perfecting it.

The problem with traditional development

Traditional software development follows a waterfall model or, at best, a poorly implemented Scrum. Projects begin with months of analysis, followed by endless design phases, fragmented development and testing at the end of the process. The result is predictable: 6 to 12 months of waiting, costs that double and a product that by the time it hits the market no longer meets the original needs.

The statistics are revealing: according to the Standish Group, 66% of software projects exceed their initial budget and only 29% are completed on time. It's a broken model that needs an alternative.

SprintMarkt's sprint methodology

Our methodology is based on three fundamental principles: absolute focus, dedicated team and daily deliveries. We don't juggle multiple projects simultaneously. When your sprint begins, a complete team of designers, developers and testers works exclusively on your app for 15 consecutive days.

How the process works

The 15-day sprint is divided into four clearly defined phases, each with concrete deliverables you can see and validate:

What types of apps can be built in 15 days?

Not all apps are candidates for a 15-day sprint. This approach works especially well for:

What a 15-day sprint is NOT

It's important to be transparent. In 15 days you can't build the next Uber, Instagram or a banking app with all regulations. Our approach is to deliver a functional, usable and published product that covers the essential business features. Advanced features are added in subsequent sprints based on real user data.

Real experience building apps

This methodology doesn't come out of nowhere: it comes from real app projects in our portfolio. For MrCoolCat Craft Beer we built a mobile app with an AI Chat with the brand's personality, a delivery game (Beer Run), an achievement system and a community wall — it exceeds 5,000 downloads and 35% of the brand's orders now arrive via the online channel. For ByDzyne we developed a React Native app with dashboard, network management and push notifications operating in 50+ countries with a 4.5-star rating. The Express Apps format packages that same experience into an MVP scope bounded to 15 days.
