One thing to keep in mind is that there is no one-size-fits-all approach to mobile app development. This means that you will find different prices or costs for mobile app development if you go from one mobile app development company to another. These are the main reasons for the significant differences in the development company's costs.
Mobile Application Types
1. Native applications
2. Hybrid applications
Native applications are highly executable programs written in the machine language of the hardware platform they are running on. Hybrid apps are typically installed in a native container that uses a mobile WebView object.
Choose a mobile app development company that has a skilled app development team that can translate and implement your ideas. Check their credibility by seeing how long they've been in your industry and whether or not they've worked with well-known brands.
Agreed 100% with your points. Mobile app development is tricky thing to do and has a lot of personalization involved. It also depends if you're working from scratch (which you probably shouldn't be doing anymore btw) or using open-source software that you can personalize.
This pandemic, my developer friend worked with a lot of larger corporations to develop personalized LMS-systems given the fact that most companies are taking training and onboarding completely in-house now when previously it was an outsourced thing.
With modern developments of open-source software though, anyone can make a system that caters to an individual company's specific needs!
