Web app or mobile app? An honest decision guide
Web app or mobile app is usually decided by instinct - mobile feels modern - rather than by what the job actually needs. For most B2B tools, the honest answer is a web app, and this post explains why, and where the real exceptions are.

Web app or mobile app is a question most businesses answer wrong by default, because "app" has come to mean a native mobile app in everyday conversation. But a web app - accessed through a browser, on desktop or mobile - does most of what a business tool needs to do, at lower cost and with none of the app store overhead.
The exceptions are real and worth knowing, but they're narrower than most first conversations assume. Start from the job, not the format.
The default: most B2B tools should be web apps
If your users are on a desk, a laptop, or occasionally a phone browser - sales teams, office staff, admin, most internal tools - a web app covers it. It works on any device without installation, updates instantly for every user the moment you deploy, and there's no app store review process standing between a bug fix and your users.
This is also almost always the cheaper build: one codebase, not two (iOS and Android), and no separate submission and update process to manage. See what is a web app for a fuller explanation of what that actually means technically.
When a native mobile app genuinely earns its cost
| Genuine reason for native | Why a web app falls short here |
|---|---|
| Needs to work fully offline, in the field | Web apps can cache some data but reliable offline-first behaviour is native's strength |
| Needs deep device access - camera, GPS tracking in the background, Bluetooth hardware | Browsers expose these with restrictions native apps don't have |
| Push notifications are core to the workflow, not a nice-to-have | Web push exists but is less reliable and less prominent than native notifications |
| Consumer-facing product competing on app store presence and discoverability | App store listing is a genuine acquisition channel for consumer products |
| Field engineers or drivers need a fast, always-available tool with patchy signal | This is the classic legitimate case - see field service scheduling below |
What a native app actually costs beyond the build
- Two codebases if you need iOS and Android, unless you use a cross-platform framework - which brings its own trade-offs.
- App store review and approval delays for every release, including urgent fixes.
- Annual developer account fees with both Apple and Google.
- A requirement to keep pace with OS updates that can break functionality without warning.
None of these are reasons to avoid native apps where they're genuinely needed - they're reasons to be sure the need is real before signing up to the ongoing cost. This connects directly to what does custom software cost, since the format you choose changes the maintenance line as much as the build line.
A worked example: field service
Field service scheduling is one of the genuine cases for a mobile-first, sometimes native, build - engineers working with patchy signal, needing offline job sheets and photo capture that syncs later. See field service scheduling software for how that specific case plays out. Compare that to an internal sales CRM used mostly at desks, which almost never justifies a native build.
How to decide, in practice
- 01List where the tool will actually be used - desk, warehouse floor, van, customer site.
- 02Check whether any requirement in the table above genuinely applies, not just feels relevant.
- 03If none do, build a web app and revisit mobile later if a specific need emerges - it's a much smaller step to add later than to remove unnecessary native complexity now.
- 04If one does apply, scope it honestly against the higher ongoing cost, not just the headline build quote.
If you're weighing this up for a real project, our mobile app development page covers where we do recommend native or cross-platform builds, and get in touch if you'd rather talk it through against your specific use case.
The W3C publishes the open standards behind what modern web apps can now do in a browser, which is worth a glance if you're being told a web app 'can't' do something - often it can.
