The verdict in three sentences
Asking a Senegalese or Ivorian customer to download a 50 MB native app on a 3G connection billed by the megabyte means losing them before the first visit. The PWA (Progressive Web App) delivers an app-like experience — home-screen icon, offline operation, push notifications — at a weight 10 to 40 times smaller. It's the technical answer to a mobile-first market with expensive data.
Native app vs PWA: weight makes the difference
A PWA installs from the browser, with no store, no update to download, and caches the catalog so it stays browsable offline.
| Criterion | Native app | PWA |
|---|---|---|
| Install weight | 30-80 MB | 2-5 MB |
| Goes through a store | yes (friction) | no |
| Offline browsing | limited | cached catalog |
| Updates | download | automatic |
| Development cost | 2 to 5x more | 350,000-900,000 FCFA |
| Push notifications | yes | yes |
What the PWA changes in the metrics
A fast site on 3G isn't a luxury: every extra second of loading drives away a share of visitors. The PWA optimizes this critical point.
| Measured PWA effect | Result (2026 benchmark) |
|---|---|
| Retention with home-screen install | +36 % |
| Load time on 3G | < 3 seconds |
| Mobile conversion | +20 % |
| Offline catalog browsing | available in cache |
| Re-engagement via push notifications | free channel |
| Weight vs native app | 10 to 40x lighter |
Home-screen installation is the key lever: once the icon is there, the customer returns without retyping a URL, and retention climbs 36 %.

Mini case study
Aminata runs a fashion store in Dakar; 70 % of her traffic comes from mobile on 3G. Her old site took 8 seconds to load; many visitors left before it finished. She moves to a PWA for 600,000 FCFA: loading under 3 seconds, catalog browsable offline, installable icon. Mobile conversion rises 20 %. On 400,000 FCFA of monthly mobile revenue, that's ~80,000 FCFA more each month, plus higher retention via push notifications — all recouped in under eight months, without the cost of a native app 2 to 5 times more expensive.
FAQ
Does a PWA really replace a native app? For an e-commerce store, yes in most cases: install, offline and notifications are covered, for 2-5 MB instead of 30-80 MB and a far lower cost.
How does the customer install the PWA? From the browser, via "Add to home screen" — no store, no developer account. An icon appears just like a regular app.
Is offline mode actually useful? Yes on unstable 3G: the cached catalog stays browsable even without network, and the order syncs as soon as connectivity returns.
Is the PWA faster on 3G? Markedly: a load target under 3 seconds thanks to caching and low weight, versus 6-8 seconds for a heavy conventional site.
How much does a PWA cost? Between 350,000 and 900,000 FCFA depending on features, i.e. 2 to 5 times less than an equivalent native app on iOS and Android.
