Also, every small to big business is an option for Android & iOS. Hence, it’s suggested to go with any one of them.
After choosing the platform, the next important thing is to decide on the app development approach. Basically, there are two main types of app development approaches, native and cross-platform.
Using native app development, you can develop an app for a single platform only. While in the case of cross-platform app development, you can build an app that works on multiple platforms (for example, android and iOS) simultaneously.
To know in detail, you can refer to this short guide on the native vs hybrid app.
As you are entering into the eCommerce app market, it is quite tempting for you to build an eCommerce app for every single platform available in the market.
