1.
Simple and quick signup process without hidden costs: When you signup, you should be able to start building your app instantly with or without a product tour — a user-friendly product takes your business users to the task immediately.
2.
Publish your app on Apple App Store and Google Play Store: Make sure your app is ready for Android and iPhones users. Look for app store support and ASO (app store optimization) from within the app builder.
3.
App design: Your app’s design tells a lot to your users about your business. It reflects your brand, appeals to engage more, and gives a lasting user experience. When selecting the right product for your business apps, one of the primary concerns should be to make sure the vendor offers a range of app designs or templates. And more importantly, you should be able to tinker or tweak these templates to represent your brand image. Design customization should go down to any granular detail or your app would end up looking like another generic template that can go against Apple's store guidelines.
4.
Scalability: The builder should be able to adapt to your changing business needs and scale along with the business growth. Look for existing features, and how likely the platform to come up with constant updates with new features to stay up to the ever-changing consumer demands.
5.
Vendor support: Ensure the vendor offers user training materials like guides, product overview, online chat, and support contacts.
6.
Comprehensive e-commerce & bookings handling: Ensure the target drag-and-drop app builder is capable of handling e-commerce to the detail. If you’re building for taking up bookings or events, ensure it can handle detailed reservations, resources, and availability calendars.
7.
Payment gateway integrations: You should offer your customers with multiple payment methods. If they don't find their preferred payment option, they might abandon the cart and move on, never to come back. Make sure your app builder supports all popular payment methods.
8.
Minimize your marketing costs: For any business, especially if you’re at the early stages, target audience reach and conversions can cost you a lot with your marketing budget. Also, consider a product with built-in features that can cut down on the marketing costs effectively.
9.
Fair pricing and best free app builder: Last but not least, the pricing. There are a few best free app builders around that allow you to create your own app at the core. When you scale up, you would be required to subscribe to the features as your business demands. So, the best free app builder, free ios app builder, and free Android app builder are virtually non-existent if you're trying to build a perfect mobile app.
