Mobile App Development by RHL Web

A mobile app puts your business on the device your customers carry all day. Done well, it makes repeat purchases, bookings and everyday tasks quicker than any website can. Done badly, it gets deleted within a week.

RHL Web plans, designs and develops mobile apps with a focus on the few things that decide whether people keep using them: speed, clarity and reliability. We handle the full process, including the backend, the admin panel and publishing to the app stores.

What is included

  • Product planning and feature prioritization
  • UX and UI design with clickable prototypes
  • iOS and Android apps from one codebase
  • Backend, database and API development
  • Push notifications and in-app messaging
  • Payments and subscriptions
  • Login with email, phone, Google and Apple
  • Offline support where it matters
  • App Store and Google Play submission
  • Updates, monitoring and maintenance

Why choose RHL Web

One codebase, two platforms

Cross-platform development with React Native or Flutter reaches iOS and Android users at a lower cost than two separate apps.

Designed around users

We prototype and test the main flows before development, so problems are found when they are cheap to fix.

Launch, learn, improve

Start with a focused first version, measure how people use it, and invest in the features that prove their value.

Cross-platform or native?

For most business apps, cross-platform frameworks such as React Native and Flutter are the right choice. They deliver a native look and feel on both iOS and Android from a single codebase, which shortens development and makes updates simpler.

Fully native development is worth the extra cost for apps that depend heavily on device hardware or demanding graphics. We will tell you honestly which approach fits your project.

Do you need an app at all?

Not every idea needs an app store listing. A responsive web application or a progressive web app (PWA) can be installed on a phone's home screen, works on every device and costs less to build and maintain. If that is the better route for your goals, we will say so. Our guide to websites, web apps and mobile apps compares the options.

App store publishing handled for you

Publishing involves developer accounts, signing certificates, privacy declarations, screenshots and store reviews. We prepare and submit everything under your own Apple and Google developer accounts, so the app and its users always belong to you.

Mobile App Development: frequently asked questions

How much does it cost to build a mobile app?

The cost depends on the number of screens, the features and the backend the app needs. After a discovery session you receive a phased, fixed-price proposal. Starting with a focused first version keeps the initial investment under control.

How long does mobile app development take?

A focused first version typically takes two to four months including design, development, testing and store approval. More complex apps are delivered in stages.

Will the app work on both iPhone and Android?

Yes. We build cross-platform apps that run on both iOS and Android from one codebase, so both versions launch together and stay in sync.

Do you also build the backend and admin panel?

Yes. Most apps need a server, a database and an admin panel to manage users and content. We build those as part of the project. See web apps and custom software.

Do you provide maintenance after launch?

Yes. Mobile platforms change every year, so apps need regular updates. We offer maintenance plans covering operating system updates, bug fixes, monitoring and new features.
