WHAT TO KNOW
Questions that make sense
Can you perform app modernization without disrupting current processes?
Yes. Our app modernization agency can use an iterative approach and update your product gradually. We can update one feature, platform or user flow at a time and roll out updates progressively instead of rewriting the whole solution. This helps to avoid disruption of your business processes.
What business challenges can your legacy app modernization services solve?
Legacy applications often create bottlenecks and dependencies that slow down business growth, increase maintenance costs, and block innovation and updates. Our modernization services aim to help businesses reduce expenses, improve application performance and reliability, enable scalability and integration with modern tools, APIs, and cloud platforms, improve key metrics, and enhance security.
How long does the app modernization process usually take?
Our application modernization experts start with a technical audit that usually takes 2-3 weeks for simpler applications and about a month for complex enterprise solutions. The actual modernization may take from 3 to 6 months or more, depending on app complexity and scope of work.
How much does it cost to modernize an app?
The final cost of modernization may depend on several factors such as application complexity, scope of work, required technologies, and integrations.
