What kind of payment structure do you follow to bill your clients? Is it Pay per Feature, Fixed Cost, Pay per Milestone (could be in phases, months, versions etc.)
At Devlight, our payment structure is typically based on a monthly billing system. We provide detailed reports and invoices at the beginning of each month, which are based on the time spent on the project. This allows for transparency and clarity in the billing process. However, we also adapt to the specific needs of each project, and the payment structure can be customized accordingly.
Do you take in projects which meet your basic budget requirement? If yes, what is the minimum requirement? If no, on what minimum budget you have worked for?
At Devlight, we don't have a fixed minimum budget requirement for projects. Instead, we analyze the functionality and requirements of each project and offer different implementation options. The minimum budget varies depending on the specific product and its features, as it should cover the expenses required to deliver a high-quality solution that meets the needs of the target audience.

While our minimum project size is typically $25,000, we understand that businesses and startups have different needs. We are always open to consulting and finding a suitable match between their goals and our services, even if it involves smaller budgets or specific support requirements.
What is the price range (min and max) of the projects that you catered to in 2022?
In 2022, the projects we catered to at Devlight had a price range starting from $25,000 and going up to $1 million. However, the actual cost varies depending on the specific requirements and needs of each client. We are also open to consultation and working with startups to help them bring their ideas to life.
Where do you see your company in the next 10 years?
While the future is uncertain and constantly evolving, at Devlight, we are committed to continually growing and evolving to meet the needs of our clients and the market. Our goal is to become the top mobile development company in the world, with a full product development cycle and offices in key locations such as the USA and UK. We hope to continue to expand our team and reach 400 employees, and to have achieved 100 million app downloads across all of our projects. While we cannot predict the future with certainty, we are excited about the possibilities and are dedicated to working hard to make our dreams a reality.

About the project
Staying open to new challenges and opportunities seems hard for big international companies. They already have a working business model and dont need to create new approaches to keep going. But this is not the case for Vodafone, which is always eager to new. Being the biggest telecommunication company in the world didnt stop them from the urge to conquer a totally new market banking. They came to us with a bare wish to build up a NEO-bank app. Our development expertise allowed us to assess the market quickly, discover insights and find the best-matching app idea according to the given requirements and limitations.

The customer is a leading telecommunications company, keeping society connected and building a digital future for everyone.

Our challenge
As clients assessed the fintech industry as quite new for them, they wanted to hear more suggestions from us on where they have to focus. So our task is logically divided into two parts:

  • - Market and customer investigations were doing everything to find strong needs and pains that can be covered by a service that can be owned by the client;
  • - Prototyping the service based on the app according to the data we collect on the first step and testing its viability. Presenting the app prototype with all inner and outer processes explanations to the client.

Services grid:

  • - Project Discovery
  • - Business model creation
  • - UI/UX design
  • - Customer development
  • - Backlog creation
  • - Technical specifications

The results of product research
Vodafone was pleased with the prototype and business model that we developed for their project. We found a way to land a massive telecommunications giant on a completely new market based on a tested and prototyped viable service.

Our Challenge
The field of medicine worldwide is gradually shifting to an electronic format for maintaining medical records, appointments with doctors, and telemedicine. is the largest Ukrainian service for online searching and making appointments for medical services. Ukrainians can make appointments in almost any clinic and not stand in line. Still, medicine is not limited to the registry, so the market needs an ecosystem for the patient's interaction with the doctor and to provide the patient with complete care for their health and data about them.

Review Summary

As the CEO of our company, our primary goal is to help individuals achieve well-being and prosperity by improving their mental and physical health. We have developed an app specifically designed to assist people in breaking old patterns and forming new habits. Our app utilizes AI-powered treatment plans to empower individuals who may be experiencing sadness, anxiety, lack of motivation, stress, or depression, allowing them to regain control over their mental health and bodies. With a vast network of workout trainers and meditation instructors from around the world, our app offers affordable, personalized, and easily accessible support anytime, anywhere.

We engaged the services of Devlight to develop our mobile iOS application and its corresponding backend, including an admin area that would enable us to manage the app's content. When searching for a mobile app development service provider, we came across Devlight through their visually appealing website. Their problem-solving approach, coupled with positive testimonials from their clients, caught our attention. Moreover, their services were both affordable and of high quality, which aligned perfectly with our requirements.

Devlight took on the responsibility of developing the iOS application based on our provided UI/UX design. They transformed our ideas into comprehensive requirements and technical documentation for the app. Additionally, they assisted us in finding a backend vendor and developing an admin panel for efficient content management within the application.

Throughout the project, we collaborated with a dedicated team from Devlight, which included a project manager, two iOS developers, and a QA specialist. We also worked with a project manager, backend developer, frontend developer, DevOps specialist, and QA specialist from the backend vendor.

The final application delivered by Devlight not only met all our initial requirements but also underwent rigorous quality testing. They provided us with all the necessary project documentation and artifacts. As we prepare for the app's production launch, we anticipate a significant growth in our customer base.

In terms of project management, I am pleased with the communication established with the Devlight team. Despite my limited involvement in the development process due to my busy schedule, the team consistently provided me with feedback and timely weekly status reports, ensuring I was up to date with the project's progress.
