Mobile app development for iOS and Android from MVP to thousands of users

For most business apps - orders, loyalty, forms, tracking - React Native or Flutter gives one codebase for iPhone and Android, which makes development and maintenance faster. Native development in Swift and Kotlin fits when the app relies on the camera, Bluetooth, sensors, heavy graphics or deep operating system behaviour. No single technology is right every time, and we are not tied to one: we map the requirements, set out the trade-offs in writing and choose together, before a line of code is written. If the first version proves the idea, the choice can still be revisited later. Many projects start cross-platform and move only specific screens to native code where it is truly needed.

A developer account with Apple and with Google in the business's name, a store listing with a description and screenshots, a privacy policy and a data collection declaration. If users can register, Apple also requires a way to delete the account from inside the app, and digital purchases must go through the store's payment system. Apple review usually takes a day to a few days, and a first rejection is not unusual. We prepare everything in advance and handle the reviewers' comments, so a first rejection does not stall the launch. The most common rejections, such as a missing test account for reviewers, are quick to fix and resubmit.

Yes, and Hebrew is built in from the first stage rather than added at the end. The interface mirrors right-to-left, including navigation, arrows and animations, input fields and keyboards behave correctly, and lines that mix Hebrew with numbers, email addresses or English names do not scramble. We also test dates, shekel currency, large font sizes and screen readers such as TalkBack and VoiceOver. If you need another language, such as English or Russian, the structure lets it be added without changing the code, so the same app can serve olim and tourists as well. We also check different screen sizes and Hebrew keyboard layouts so the experience stays consistent on every supported device.

For card payments we connect an acquirer or payment processor you already work with, and the charge goes through the server rather than being stored on the device, so card details are never kept inside the app. Selling digital content inside the app is subject to store rules. Push notifications are sent through Apple and Google services and triggered by events or campaigns. The important part is asking for permission at a moment when the reason is clear, and giving users control over the types of messages, because a user who turns notifications off rarely turns them back on. Together we decide which data is stored on the server, for how long and who can access it, and this is written into the privacy policy.

An app is not a project that ends: every year new versions of iOS and Android ship, the stores change their requirements and third-party services update. After launch we watch crashes and ratings, fix issues, update for new system versions and release improvements based on what the analytics show. Maintenance can be a monthly plan with written response times, or it can be handed to an in-house team. Without it, an app usually stops meeting store requirements within a year or two, and the store may remove it or stop accepting updates. It is worth agreeing the expected scope of maintenance in advance, so a new system release does not catch you by surprise.

The code, the design and the developer accounts belong to you. At the end of the project you receive the app code and the backend in a repository you control, a document explaining the structure and how to build and publish a release, the design files, and access to the Apple, Google, analytics and server accounts. That lets you switch vendors, hire an in-house developer or stay with us, without dependence. Every third-party library used in the project is recorded together with its licence, so there are no surprises in due diligence or if the business is sold. If you wish, we also give your team a short handover on building, publishing and managing releases so the next steps are simple.
