Choosing between a bespoke mobile app and an off the shelf app depends entirely on the size and complexity of your main business goal. Smaller, more simple tasks where the requirement is very specific, such as calendar management or task tracking, are often solved with off-the-shelf products. Whereas more complex business objectives which require more data collection and various features, such as streamlining the delivery service and improving customer engagement, are better answered with a bespoke app.
An off-the-shelf app may be a cheaper and quicker option when compared with developing a bespoke mobile app, but you will never truly own that software, which means you will be unable to make any changes to the app or sell it on as a service. A bespoke mobile app can be a better long-term investment, especially if your business has plans for growth.
