Andromo

Andromo is one of the most popular free android app maker platform for mobile app development without coding. You can create a mobile app with just three steps. To create a mobile app using Andromo, you simply need to, fill out a few simple forms, add features, graphics, content and everything else that makes your app unique, and build your app with the click of a button.

Unlike many other developers, Andromo doesn't have a preview, so you cannot see how the app will look when you add or resize elements.

Basic plan is free but you can upgrade to the $8 per month plan to start creating up to 50 programs. This is what makes Andromo one of the top android app development software for creating app without coding.
