The verdict in three sentences
A PWA (Progressive Web App) gives your store the speed and comfort of an app — offline browsing, push notifications, home-screen icon — without store fees or friction. It costs almost 0 FCFA to install versus 2 to 5 million FCFA for a native app, and loads in under 3 seconds on 3G where a heavy site takes 8 to 12 s. On the slow networks of Kampala or Ouagadougou, that's what separates a sale from an abandon.
PWA vs native vs responsive site
Three approaches, three budgets. The table below sets the 2026 orders of magnitude.
| Criterion | Responsive site | PWA | Native app |
|---|---|---|---|
| Upfront cost | 0-500,000 FCFA | included / low | 2-5,000,000 FCFA |
| Store fees | 0 | 0 | ~15,000 FCFA/yr + 15-30 % |
| 3G load | 8-12 s | < 3 s | < 2 s |
| Offline browsing | No | Yes (cache) | Yes |
| Push notifications | No | Yes | Yes |
| Install | — | Home screen | Store |
| Updates | Instant | Instant | Store review |
The business impact on slow networks
A PWA's gains aren't cosmetic: they show up in retention and data saved, two make-or-break factors in the region.
| PWA lever | Measured effect (2026 order) |
|---|---|
| Offline cache | Browsing continues on drop |
| Push notifications | ~15 % of dormant users reclaimed |
| Add to home screen | 5-10 % install conversion |
| Asset caching | ~40 % data saved |
| Lighthouse PWA score | Target 90+ |
| Load time | Drops from 8-12 s to < 3 s |

Fatou runs an online shop in Kampala: 3,000 visits/month, 1.2 % conversion (36 sales), 18,000 FCFA basket. Her site takes 9 s to load on 3G. She switches to a PWA: load < 3 s, conversion at 1.6 % (+33 %) i.e. 48 sales, plus 12 sales/month. Push reclaims ~15 % of her 400 dormant customers. Direct gain: 12 × 18,000 = 216,000 FCFA/month, i.e. 2,592,000 FCFA/year, for a modest PWA build cost versus a 3,000,000 FCFA native app.
FAQ
Does a PWA really replace a native app? For 90 % of stores, yes: it offers push, offline and a home-screen icon without the 2-5 million FCFA or store review. Native is only justified for heavy hardware needs.
Does a PWA really work offline? Yes: the cache lets shoppers keep browsing pages they've seen even on a drop, and syncs the cart when the network returns. That's decisive on unstable 3G.
How much data does a PWA save? About 40 % by caching repeated assets (logo, fonts, product images). On a capped data plan, that's a real retention argument.
Are push notifications effective? Yes: they reclaim about 15 % of dormant users, provided they're targeted (back-in-stock, promo) and not spammed, or users uninstall.
What Lighthouse score should I target? Aim for 90+ on the PWA audit and mobile performance. Below 90, 3G load often exceeds 3 seconds and conversion suffers directly.
