Choose a platform depending on development costs:
Before deciding on a platform, you need to consider the total development costs and client budget. In this way, you can download and install a platform that pays for both.
From design costs to testing costs, the cost of the paid version of the tools you might need to develop, and others, you need to calculate the sum of all of them.
Think about the devices that your application needs to support:
Android supports more than 160 devices and is still trying to increase the number. IOS also supports various devices such as iPad, iPod, iPhone, and many others. You can visit https://2damcreative.com/how-much-does-it-cost-to-build-an-app/ to know the cost of developing a mobile app.
If you compare the two owners of this market, you might face severe challenges in building applications for both for different budgets.
If you are considering Windows, it supports around 100 devices, while Blackberry supports about 10. Now you no longer need to worry about the last two because they are currently not used by many people and almost nothing on the market.
For example, let's say WhatsApp is one of the most popular applications that has refused to support the last two, but yes, it also supports iOS and Android. With this in mind, you need to choose a development platform that allows you to build successful applications for Android and iOS.
In addition, you should consider additional programming costs if necessary. All of this together can help you make the best choice for an application development platform.
