Apps need a repeated reason to exist
An app is useful when customers, staff, or owners return to complete a workflow, track status, submit information, or review data.
A responsive web app may be enough
Many business apps do not need app stores. A mobile-friendly web app can be faster to build and easier to maintain.
Start with the job to be done
The question is not whether an app sounds impressive. The question is what job it performs better than the current process.
