Before you build a mobile app, you must decide which phones it will run on. The answer changes the cost, the timeline and who can use it from day one.

Start with your users

Find out what phones your customers or staff actually use. In many markets, including Pakistan, Android phones are more common than iPhones, but your own audience may be different. Ask a sample of real users instead of guessing.

Your options

One platform first. Build for the phones most of your users have, learn from them, and add the second platform later.
Native apps. Separate apps built specifically for Android and for iPhone. They give the best performance and access to every phone feature, and they cost the most because there are two builds.
Cross-platform apps. One codebase produces both apps. Tools such as Flutter and React Native work this way. This usually lowers cost and speeds up delivery, and suits most business apps.
A web app on the phone. A website built to behave like an app. It needs no app store, but it cannot use every phone feature.

Questions that point to an answer

Do you need the camera, push notifications, location or offline use?
Do your customers expect to find you in an app store?
Is speed to market more important than the finest polish?
Would a web app already solve the problem?

Things people forget

Both app stores require a developer account, and Apple charges a yearly fee.
Store review takes time, and apps can be rejected for rule problems.
Phones and operating systems change every year, so apps need updates.

If you are not sure an app is needed at all, read website, web app or mobile app: which one do you need. We build mobile apps among our services, and we will tell you if a simpler option fits better.

Cross-platform tools in more detail

Flutter and React Native are two widely used ways to build one app that runs on both Android and iPhone. The main benefits are lower cost and a shared codebase. The trade-offs are that some phone-specific features can need extra work, and the app may not feel quite as polished as a fully native one in demanding cases. For most business apps, such as booking, ordering, catalogues and staff tools, cross-platform works well.

App store basics

Each store needs a developer account, and Apple charges a yearly fee.
Every new version goes through a review, which can take time.
Stores have rules about privacy, payments and content. An app that breaks them can be rejected.
You need a privacy policy, screenshots and a description before you publish.

After launch

An app is not finished at launch. Phone systems change each year, so apps need updates. Plan for fixes, small improvements and support, and track how people use the app so you know what to improve next.

Frequently asked questions

Which is cheaper to build, Android or iOS?

The cost is similar for each one on its own. What changes the total is whether you build for one platform, two separate native apps, or one cross-platform app.

Do I need a back end for my app?

If the app stores data, has user accounts or shows content that changes, yes. The back end is the server side that stores and serves that data. A very simple app that works only on the phone may not need one.

How long does an app take to build?

It depends on the features. A small app can take a couple of months, while a larger one takes longer. Ask for a timeline that includes design, testing and store review.
