App development for Android, iOS and the web
We build apps people actually use: for your staff, field teams, partners and customers. From discovery and prototype to release on Google Play, the App Store or the browser — then we keep them running.
Signs your business needs its own app
If important work still runs on chat groups and spreadsheets, the right app can save hours every week.
Data scattered across chats
Reports, photos and approvals live in many groups. An app puts them in one flow.
Field teams are hard to follow
Location check-ins, visits and daily tasks are logged automatically for managers to see anytime.
Customers expect fast service
Ordering, payment, status and notifications right on your customer's phone.
Features we often build
Every app is designed around your workflow. These are the parts most often needed.
Login & user roles
Different access for admins, managers, staff and customers.
GPS, camera & scanning
Location check-ins, photo proof, barcodes and QR codes.
Notifications
Task reminders, order status and important announcements.
Payments
QRIS, virtual accounts, e-wallets and cards via a payment gateway.
Offline mode & sync
Keeps working on weak signal; data syncs when back online.
Integrations & APIs
Connects to your ERP, accounting, WhatsApp or existing systems.
Android, iOS, web, or all of them?
We help you pick the form that makes the most sense for your users and budget.
| Type | How it works | Best for |
|---|---|---|
| Web app | Opens in a browser on any computer or phone, no install. Updates reach everyone at once. | Internal systems, customer portals, admin panels |
| Android app | Installed from Google Play or directly (APK); can use camera, GPS and notifications. | Field teams, sales, members, loyal customers |
| iOS & cross-platform | One codebase for Android and iPhone (e.g. Flutter), released to both stores. | Public apps with iPhone users |
| Web + mobile | A web panel for managers and a mobile app for users, sharing one database. | Organisations with admins and many users |

Technology
How much does an app cost?
It depends on features, user types, platforms (Android, iOS, web) and integrations. After an initial discussion we send a written, per-feature estimate. Projects can also be split into phases.
Can the app run on iPhone too?
Yes. We can build a cross-platform app for Android and iOS, or a web app that opens on any phone in the browser.
How long does it take?
It depends on complexity. We usually release a first version with core features so you can start using it early, then add features in phases. The schedule is in the proposal.
Can the app connect to our existing systems?
Yes, through an API or the database — for example your accounting system, ERP, website or dashboard.
Who looks after the app after launch?
We do. Through yop/care we handle OS updates, bug fixes, backups, server monitoring and new features.
