Should your business have a mobile app? Seven reasons, tested
The common reasons for building a business app, with the question to ask about each, and the costs and store rules that decide whether it is worth it.
Apps are no longer only for large companies, and small firms in Singapore build them too. But an app is a product with running costs, not a one-off brochure. Here are the seven reasons businesses usually give for wanting one, each with the question that decides whether it holds for you.
1. “Our customers are on their phones”
Many are, but a phone also runs a browser. The real question is whether customers would install something from you and come back to it. If they visit once or twice a year, a fast mobile website reaches them without asking them to download anything.
2. Brand presence
An icon on someone’s home screen is a daily reminder of your business. That only works if people keep the app, which brings you back to giving them a reason to open it. An app that is just your website in a wrapper is also likely to fail Apple’s App Review Guidelines, which ask for more than a repackaged website (guideline 4.2).
3. Being available around the clock
An app can take orders, bookings or enquiries at any hour. So can a good website. The app wins when the task needs something a phone does better: location, the camera, offline use, stored payment details or a signed-in account.
4. A direct channel to customers
Push notifications reach people without an algorithm in between, which is the strongest argument for an app. They come with rules: Apple’s guideline 4.5.4 requires explicit opt-in in the app before notifications are used for marketing, plus an in-app way to opt out. Under the PDPA, personal data may only be used for the purposes people consented to. Used sparingly for things customers want, such as order updates or appointment reminders, this channel is valuable. Overused, it gets switched off.
5. Digital loyalty programmes
Replacing stamp cards with an app gives customers one less thing to carry and gives you data on repeat visits. Check the data side first: a loyalty programme collects purchase histories tied to people, so consent, protection and retention all apply.
6. Reaching younger customers
If your customers already handle bookings, payments and messages on their phones, an app can fit their habits. Ask what you will offer that they cannot already get elsewhere.
7. Better engagement
Apps can offer things a website cannot easily do: saved preferences, reordering in one tap, live status updates. Engagement comes from those features, not from the app existing. List the ones you would build and how often a customer would use each.
The cost of keeping one
Whatever the reason, an app needs upkeep. Apple now requires uploads to be built with Xcode 26 or later, and Google requires new apps and updates to target API level 36 from 31 August 2026. These requirements rise every year. Add that to hosting and support, and set it against what the app earns or saves. The cost article and the maintenance guide help with the numbers.
A quick test
An app is likely worth building if customers would use it at least monthly, if it does something a website cannot do as well, and if you can name who will maintain it. If two of those three are missing, start with the website.
