You need users to install your 'app' on their phones — but building a native iOS + Android app is too expensive (IDR 30-100M) and complicated (you have to submit to the App Store and Play Store, with reviews taking days). A Progressive Web App (PWA) is the middle ground: a website installable like an app, appearing as an icon on the home screen, running in its own window (no address bar), capable of push notifications, and with offline features for pages already opened. The investment is just a tenth of a native app, and it can be updated anytime without users having to download again. From IDR 3M, usually 3-5 weeks. Perfect for online stores with repeat customers, an internal employee app, or a product that needs push notifications without the Play Store drama.
// why this matters
Context & rationale.
Many small businesses and startups are stuck in a dilemma: a 'mobile app' becomes a perpetually deferred dream because building a native iOS+Android app is too costly. Meanwhile, their competitors who have an app gain a big advantage — push notifications that land instantly, fast access from the home screen, and a 'truly serious' perception. A PWA closes this gap at 10-20% of native cost. Famous case studies: Twitter Lite, Pinterest, Tokopedia Lite — all used a PWA with surprising results (engagement up 70%, retention up 40%). For the Indonesian context, where many users have entry-level phones with limited storage, a PWA is even more favored because of its small size (< 5 MB) compared to a native app (50-200 MB). Modern PWA push notifications are now supported on Android and iOS 16.4+, so practically every smartphone user can be engaged. For businesses focused on repeat customers (online stores with subscriptions, internal apps, daily services), a PWA often becomes a significant retention unlock.

// our process
How we work.
01
Audit the Existing Website
If you already have a website, we audit its readiness to become a PWA: performance, structure, and caching needs. Many are already 70% ready, with just the PWA layer left to add.
02
Caching & Offline Strategy
Determine which pages are cached aggressively (homepage, catalog) and which must always be fresh (cart, checkout). A wrong caching strategy = stale data stuck on the user, with no updates.
03
Build the PWA Layer
Building the manifest, service worker, a complete icon set (192px, 512px, maskable), splash screen, and offline page. Setting up push notifications with a server backend to send broadcasts.
04
Optimize the Install Prompt
Not just throwing up an install prompt — we trigger it at the right moment (after the user engages for 30 seconds, or after the first purchase). Studies show prompt timing determines install rate by 5x.
05
Multi-Platform QA
Testing on Chrome Android, Safari iOS, Edge Windows, and Chrome desktop. PWAs behave differently on each platform — we make sure the experience is consistent.
// technical approach
How it works under the hood.
A PWA isn't a single technology, but a collection of modern web standards assembled to mimic the native app experience. The key is the service worker — a script that runs in the background and can intercept network requests. With a service worker, we can cache assets aggressively (HTML, CSS, JS, images) so pages already opened load instantly even offline. Our caching strategy uses a 'stale-while-revalidate' approach for content that can tolerate slight staleness, 'network-first' for content that must always be fresh, and 'cache-only' for static assets. The manifest.json defines the look when installed: icon, app name, theme color, and display mode (standalone so there's no address bar). Push notifications are implemented with Firebase Cloud Messaging or the native Web Push API, with an opt-in that requests permission at a high-value moment (not the instant the user lands). For iOS, we use specific workarounds (apple-touch-icon, viewport meta) so the look when installing from Safari stays tidy. The PWA auto-detects updates the next time the user opens it, and we prepare a user-friendly 'a new version is available, click to update' prompt.
// perfect for
Ideal if you...
- Online stores with repeat customers who visit frequently
- Businesses with a daily service (delivery, news, fitness tracker)
- Internal employee apps without deploying to an internal Play Store
- Communities/forums with high engagement
- Startups that need a 'feels like an app' without native app cost
// not a fit for
Maybe not you if...
- ×Apps needing heavy hardware features (AR, advanced camera, sensors) — native is better
- ×Games with high-end graphics — a native engine fits better
- ×Apps that strictly need Play Store/App Store distribution for credibility
// real example
Dapur Bunda — A Weekly Catering Ordering App
Dapur Bunda sells weekly catering packages for office workers. Customers have to order every Sunday night for a Monday-Friday package. They previously used a WhatsApp group, often missing messages and getting orders mixed up. We converted the ordering website into a PWA: customers install it on their home screen, get a push notification reminder every Sunday at 6 PM, and choose a menu for the week on an easy interface. After 3 months, 78% of regular customers had installed the PWA, push CTR averaged 42% (far above email's 12-15%), and weekly orders rose 23% thanks to consistent reminders.
outcome
78% install rate, 42% push CTR, orders up 23%, cost 1/8 of a native app
