It totally depends on what client will get if you solve their issue. For example: If you are working on an app which generates $100K/month in revenue you should charge based on flat rate. Your value to the project helps them to generate revenue. Every client wants to get benefit hiring someone who can solve their issue. In this case, you will develop their bug-free app which helps them to sell on apps store and google play store. Your charges always depend on what value you provide to your clients.
Hi Paisearchguy,
If you have skills in JavaScript, React Native, you can still become a hybrid app developer. You can use fusetools, ionic frameworks. If you have skills in Swift language you can become complete iOS app developer which will be easy for you to present yourself as an iOS app developer.
Based on your portfolio of work you can make the transition from marketing to the developer. Clients wanted to someone to solve their issue. Moreover, I worked with many junior developers who got 2 months of training in swift language, they are not successfully become a full-time developer so you can be.
I always prefer my clients to go for the custom native app. They wanted to have hybrid app for their hotel app. I feel hybrid apps are slow in performance and lack standard os UI.
Custom apps serve better and stand out among other rivals. You can create the app based on your customer's needs. That can be only done by custom mobile app design. It will boost product brand and user engagements ie: Airbnb, Uber, Tinder are good examples of custom native apps.
