Engagement Models
Need technical skills or expertise? A dedicated software engineering team can quickly strengthen your in‑house resources and work as a natural extension of your company, under your guidance or ours. This model is ideal for long‑term or larger‑scope projects, when you are running several projects or a pool of tasks at once, or do not yet have a clear vision of future project objectives. Learn how a dedicated software engineering team can support your projects and help you confidently scale your business goals.
Fixed cost pricing is best suited for software engineering projects with a clearly defined scope that is not expected to change. It gives clients the confidence to plan ahead and set an exact project budget without surprises. If the scope is still undefined, we can first work with you to develop high‑level specifications and align expectations. Once everything is agreed, you receive a proposal that outlines timeframes, costs, team structure, and all key deliverables in one clear snapshot.
This model usually applies to prototypes or projects where the client, and therefore our developers, do not yet have a clearly defined scope. The client pays for work completed based on agreed‑upon benchmarks and milestones, with full visibility into progress. In this setup, the client plays a more active role in shaping software solutions and accepts the risks related to how the scope of work may evolve. A dedicated team is assigned to the project, and billing is based on the actual time accrued for their work.

Clients Testimonials
Finding a reliable partner for mobile app development is no easy task. To be honest, we approached selecting a vendor with great caution, as we've dealt with missed deadlines and communication issues on previous projects.But from the very first day of working with 24Gen, I knew this time would be different. What impressed me most was their approach to project management. Everything was organized so smoothly and clearly that the complex development process felt surprisingly simple. The team was always available, kept us updated on every step, and answered our questions almost instantly. We never felt like we were "just another client."
And most importantly - the deadlines. In our industry, delays can be very costly, so punctuality was critical for us. The 24Gen team delivered the project exactly on schedule, without a single setback. That’s a level of reliability you rarely find these days.
In the end, we didn't just get a project completed on time; we gained confidence that we've found a partner we can count on for the future. Without any hesitation, I recommend 24Gen to anyone looking for a team that delivers quality work with integrity.

FAQ
What can be done to ensure the app can handle a sudden surge in users without slowing down?
To prepare your app for success, we build a "margin of safety" into its architecture from the very beginning. We construct the system from independent modules (this is called a microservices architecture), which allows for flexible load distribution. If one feature becomes very popular, we strengthen only that part without affecting the rest of the app. Using cloud technologies allows us to get additional resources almost instantly as soon as they are needed. This ensures that the app will run quickly and stably, regardless of how many people are using it at the same time.
How can we save money on development but still get a high-quality product?
To optimize the budget, we first focus on the essentials by creating a minimum viable product (MVP). This allows us to launch the app quickly with key features and avoid spending money on things users might not need. We also save you time and money by using pre-built, time-tested components and, where possible, cross-platform technologies so we don't have to write code twice for iOS and Android. And thanks to our flexible Agile methodology, we constantly check in with you to make sure we're moving in the right direction and not doing unnecessary work.
How do we get the app to "play nice" with our internal systems and external services, like for handling payments?
We make sure your app becomes a fully integrated part of your IT infrastructure. We can connect it to anything: your CRM, database, analytics tools, or payment systems. Our team creates special "bridges" (APIs) that allow data to be transferred securely and smoothly between the app and other systems. So, if you need orders from the app to instantly appear in your accounting system, we'll make it happen.
How do you protect the app and user data, especially when it involves finances or personal information?
We take security as seriously as possible. From the very beginning, we build the app to be difficult to hack, using international security standards (OWASP). We encrypt all data, especially sensitive information, so that no one can read it. For logging into the app, we implement the most reliable methods: fingerprint, facial recognition, or two-factor authentication. If your app handles finances (PCI DSS), personal data of Europeans (GDPR), or medical information (HIPAA), we guarantee full compliance with all these strict regulations.
What are the realistic timelines for building an Android app from scratch?
It all depends on the scale of the idea. If we're talking about a basic first version (MVP) to test a hypothesis on the market, it will take about 3-4 months . However, if a complex application with many features is required—like a financial service or a video platform—then development could last from 6 to 12 months . We follow a flexible (Agile) approach, so you'll get a working prototype fairly quickly, allowing you to start gathering user feedback and improving the product while it's already live.
Can you implement complex, innovative features in the app, for example, using artificial intelligence?
Yes, absolutely. We love complex challenges. We have a dedicated R&D team that constantly monitors trends and tests new technologies. So, if you want to implement smart user recommendations, voice control, augmented reality (AR), or any other modern feature in your app, we know how to do it. Our goal is not just to use trendy technologies, but to make them solve specific business problems and help you stay one step ahead of the competition.
What if we decide to switch developers? Will there be issues handing over the project?
We work in a way that ensures you are not "locked-in" to us. All source code belongs to you by default. We use standard, open-source technologies and create a clear, modular architecture so that any other team can understand the project. Upon completion, we provide all technical documentation and conduct a detailed knowledge transfer session, so you retain full control and freedom of choice for the future.
How do you ensure the app works equally well across the huge variety of different Android smartphones?
This is indeed one of the main challenges in Android development. We tackle it comprehensively. First, we design the UI from the ground up to be "responsive," automatically adapting to any screen—from a small budget phone to a large tablet. Second, we use modern libraries from Google (Jetpack) that help smooth out the differences between Android versions. And most importantly, we thoroughly test the app on numerous real devices and emulators to ensure everything looks and works perfectly, regardless of the smartphone's brand, screen size, or year of release.
Does the work on the app end after it's published on Google Play? How do we know if it's successful and how can we evolve it?
No, publishing is the start of the most interesting phase. We immediately connect analytics systems (like Google Analytics) to the app to see everything that's happening inside: which features are used most often, at what stage users drop off, what they like, and what they don't. This allows us, based on real data rather than guesswork, to continuously improve the app: making it faster, more user-friendly, and adding the exact features users are waiting for. It's a continuous process that helps to grow and evolve the product.
What are the most common "pitfalls" that companies fall into when creating Android apps?
We've seen many projects and can highlight three main mistakes. First, chasing the number of features instead of solving a real user problem. The app becomes complex and bloated, but not useful. Second, neglecting performance. Even the most feature-rich app will be deleted if it's slow. Third, and very common, is abandonment. Companies release an app and then forget about it. But it needs to be constantly updated, improved, and secured to remain relevant and safe for users.
Most importantly, the project was delivered exactly on time—a rarity that is incredibly valuable in our industry. We have found a partner we can truly trust. I recommend them without hesitation.
