Mobile app development

Order a mobile app: iOS, Android and cross-platform

Updated 20 October 2026

First: platform and approach

A mobile app can be built in different ways. Native development separately for iOS (Swift) and Android (Kotlin) gives the most possibilities but costs more, because it is effectively two projects. Cross-platform (Flutter, React Native) lets you have one code base for both systems, which is usually cheaper and faster, though it suits some complex tasks less. There is also an option without app development: a web app that works in the browser.

The choice depends on the idea and the budget. For booking customers or delivery, cross-platform is often enough. For complex graphics or work with hardware, ask developers what they advise.

How it works on BlaBlaPrice

You write one request: what the app should do, for whom and on which platforms. Developers reply in the chat with offers: a price or what it depends on, timelines, technology, scope of work. They compete for your request and see their place among the others, so terms often improve. Reviews are visible next to each, and contacts go only to the provider you choose.

What to put in your request

• Idea — what kind of app: customer booking, delivery, shop, learning.
• Platforms — iOS, Android, both, cross-platform.
• Features — payment, push notifications, geolocation, chat, user accounts.
• Screens and roles — approximate number of screens and types of users.
• Design and brief — whether you have Figma designs and a description, or they need to be created.
• Backend and integrations — server, admin panel, links with a CRM and payment systems.
• Publishing and support — whether you need it listed on the App Store and Google Play and maintained after launch.
• Deadline and budget — by when and the amount, if you want to name one.

Example: “I need an app for booking customers at a beauty salon in Pretoria, iOS and Android, about 20 screens: payment, push, geolocation. I have Figma designs, and I need an admin panel and CRM integration, plus publishing in the stores. Deadline 3 months, budget up to R 120,000.”

How to compare offers

Make a list of features for yourself and compare the offers against it. Often one studio counts design, backend, admin panel and publishing in the price, and another only the mobile part. Ask also about testing on real devices and how errors are fixed after release.

Ask for examples of finished apps in the stores: you can download and assess them. Find out who owns the source code and the App Store and Google Play accounts. It is better when the developer accounts are registered in your name or your company's.

Common mistakes

• Trying to fit all ideas into the first release. It is better to launch a simple MVP and grow it.
• Not counting costs after launch: server, updates, store rules, support.
• Not checking the App Store and Google Play publishing requirements, which can delay the release.
• Having no contract on the rights to the code and design.
