The verdict in three sentences
For field teams working on 3G or off-network, an offline-first PWA is in 2026 the most rational choice: 6 to 15 M FCFA (roughly 9,000-23,000 EUR) for a single codebase, no store fees, deployable in 8 to 12 weeks. A native app (12 to 30 M FCFA) is justified only if you need deep hardware access (advanced Bluetooth, specific sensors) or perfectly reliable iOS push notifications. The deciding criterion is not the app's polish but its ability to work with no connection and sync the moment the network returns.
PWA vs native app: the 2026 comparison
Both approaches deliver a mobile app, but their economics and constraints differ sharply.
| Criterion | PWA | Native app (iOS + Android) |
|---|---|---|
| Development cost | 6 to 15 M FCFA | 12 to 30 M FCFA |
| Codebases | 1 only | 2 (Swift + Kotlin) or 1 (Flutter) |
| Store fees | None | Apple 99 USD/yr + Google 25 USD |
| Offline mode | Excellent (service workers) | Excellent |
| Push notifications | Good (Android), limited (iOS) | Excellent |
| Advanced hardware access | Limited | Full |
| Time to delivery | 8 to 12 weeks | 14 to 24 weeks |
| Updates | Instant (web) | Store review |
For most field cases (data entry, photos, geolocation, forms), the PWA meets the need at half the cost.
Field use cases and recommendation
The right choice depends on real field usage, not on technology preferences.
| Field scenario | Key need | Recommendation |
|---|---|---|
| Surveys and entry in rural areas | Robust offline, deferred sync | PWA |
| Photos + geolocation | Camera, GPS, offline | PWA |
| Delivery with barcode scan | Camera scan, signature | PWA (native if scan-intensive) |
| Critical real-time iOS notifications | Reliable iOS push | Native |
| Industrial sensors / advanced Bluetooth | Deep hardware access | Native |
| Multi-purpose internal app | Controlled cost, fast rollout | PWA |
On unstable 3G, an offline-first architecture (data stored locally then synced) is not optional but mandatory: without it, the app is unusable outside cities.
Total cost over 3 years
Build price is only part of the equation. Here is the 3-year estimate.
| Item | PWA | Native iOS + Android |
|---|---|---|
| Initial build | 6 to 15 M FCFA | 12 to 30 M FCFA |
| Store fees (3 years) | 0 FCFA | ~230,000 FCFA |
| Annual maintenance | 1 codebase | 2 codebases |
| Sync/hosting cost | 60,000 to 150,000 FCFA/month | 60,000 to 150,000 FCFA/month |
| 3-year total (order of magnitude) | Markedly lower | Markedly higher |

Bernard, logistics director of a distribution company in Singapore, must equip 25 drivers and field agents. A native iOS + Android app is quoted at 22 M FCFA; an offline-first PWA at 11 M FCFA. His agents work mostly on 3G, with dead zones. The PWA stores delivery notes locally and syncs as soon as the signal returns. Immediate saving: 11 M FCFA of build, plus a single codebase to maintain. The ROI of digitizing (end of paper notes, near-real-time tracking) is estimated at 8 months. The PWA choice is clear-cut.
FAQ
Does a PWA really work offline?
Yes, thanks to service workers and local storage. Entered data is kept on the device and synced automatically when the connection returns, which is essential on unstable 3G.
Can a PWA be installed like a real app?
Yes, it adds to the home screen and opens full-screen with no browser bar. The experience is very close to native, without going through the stores.
How much does a field PWA cost in 2026?
Expect 6 to 15 M FCFA (roughly 9,000-23,000 EUR) depending on complexity (screen count, sync, integrations). A simple field MVP sits at the bottom of the range.
When do you truly need native?
When you need ultra-reliable iOS push, deep hardware access (advanced Bluetooth, sensors) or extreme graphics performance. Otherwise the PWA covers most business uses.
Does a PWA handle camera and GPS?
Yes, a PWA accesses the camera, geolocation and local storage. It covers photo, scan and geo-tagging used in the field.
