Your customers live on their phones, so your business should too. Serina Systems designs and builds mobile apps that are simple to use, quick to load and genuinely useful, helping you serve customers better, take bookings and orders, and run your operations from anywhere.
We start with your goals and your users, design a clean interface you can try before we build, and then develop a secure, reliable app with a back end that keeps everything in sync. We build native Android apps with Kotlin as well as cross-platform apps that can reach both Android and iPhone, depending on what suits your budget and audience.
What We Build
Whatever your industry, we turn your idea into an app people love to use. Here are the kinds of mobile apps we build most often.
Branded apps that put your services, catalogue and contact options in your customers’ pockets.
Shopping apps with product browsing, carts, secure checkout and order tracking for your online store.
Appointment, reservation and scheduling apps with reminders for salons, clinics, hotels and service businesses.
Learning and student apps with accounts, content, progress tracking and easy communication.
Inventory, staff, student and records management apps that replace paperwork and spreadsheets.
Ordering, dispatch and delivery tracking apps that keep customers and riders connected.
Apps that connect to your existing website or system so data stays in sync everywhere.
New features, OS compatibility updates, bug fixes and performance tuning after launch.
A well-built app keeps your business one tap away from your customers. It builds loyalty, makes everyday tasks faster and opens up new ways to earn, all while giving you a smoother, more professional experience than a website alone.
Your brand sits on your customers' home screen, one tap away every day.
Push notifications bring customers back with offers, reminders and updates.
Apps load quickly and feel natural on a phone, keeping users happy.
Your app talks to your website, database and tools so nothing is duplicated.
We pick the right tools for each project so your app is fast, secure and easy to maintain.
No hidden extras. These essentials come standard with every app project we deliver.
A clear six-step roadmap takes your app from first idea to the app store.
We learn who your users are and what the app must achieve, then define the features that matter most for a first release.
We map the user journey and design clean, thumb-friendly screens, then share a clickable prototype you can try on your phone.
We build your app in short stages, connecting it to a secure back end, database and any services it needs.
We test on real devices and different screen sizes, fix bugs and tune performance and battery use before release.
We prepare your store listing and screenshots and guide the app through submission to Google Play, and the App Store where needed.
After launch we monitor crashes and feedback, keep the app compatible with new phone updates and add features as you grow.
The cost depends on the features, the number of screens, whether you need Android only or both Android and iPhone, and what back end is required. After a free consultation we send a clear, fixed quote so you know the full cost before we start.
A simple app can take around four to eight weeks, while larger apps with accounts, payments or custom back ends take longer. We give you a clear schedule in your proposal.
It depends on your customers. Android is very popular in Kenya, so many businesses start there and add iPhone later, while cross-platform builds can reach both from one project. We will recommend the best option for your budget and audience.
Many apps need a secure back end to store accounts, orders or content. We build and host this for you, and can connect the app to your existing website or system.
Yes. We prepare your store listing and guide the submission process. Store developer accounts have their own fees, which are paid directly by you, and we help you set them up.
Yes, where it makes sense. We can store key information on the phone so users can keep working with a weak connection and sync once they are back online.
We stay with you. We monitor crashes and feedback, keep the app compatible with new phone updates and add new features whenever you are ready.
