No-Download Event App: PWA, Not the App Store
What is PWA and why it’s the future of event apps
A Progressive Web App (PWA for short) is an application that opens in your phone's browser but looks and works like a regular mobile app. You don't need to download it from a store - just click a link or scan a QR code. It can send push notifications, and it keeps the entry QR code saved on the phone.
Why does this matter for event organizers?
Every barrier between an attendee and the app means some people simply won't use it. A traditional store app requires downloading, phone storage, and sometimes creating an account. A PWA needs no store download. Registration and sign-in depend on the access settings chosen by the organizer. An attendee scans a QR code and within seconds has a full event app with the agenda, directions, hotel information, and organizer contact details.
A PWA opens in a modern browser on iPhone, Android and tablets. A custom store app needs releases for iOS and Android, but the two versions can share code.
How it works in practice - from QR code to home screen
Imagine a typical conference. An attendee approaches the registration desk and scans a QR code from the stand. Within 2-3 seconds, the full app opens on their phone - agenda, maps, hotel information, and organizer contacts. If they want quick access later, they tap "Add to Home Screen" and they're done. The app icon appears on their phone and works like a regular app.
A store app needs downloading first, and on weak venue signal that is one more obstacle. EventApp opens straight away in the browser.
For organizers, it's simpler too. Instead of preparing separate instructions for iPhone and Android users, a single universal QR code is enough. You can also send the link in the registration confirmation email or place it on the event website. Attendees can browse the agenda, check directions, find hotel information, and plan their day before they even arrive.

5 concrete advantages of a PWA event app
- Attendees use the app immediately - no store download needed. At large events, every additional barrier can mean hundreds of people who never open the app.
- Works on every phone - a single PWA supports iPhones, Androids, and every modern browser. The organizer doesn't need to publish and maintain versions for two different operating systems.
- Changes visible instantly - if a session room changes, a new item is added to the agenda, or live voting results come in, the update appears in seconds.
- Lower costs - instead of building and maintaining separate apps for iOS and Android, the organizer invests in one version. A smaller team, faster changes, lower costs.
- More people use the app - the fewer steps to launch, the more attendees actually use it.
Push notifications and offline mode - does PWA deliver?
Push notifications
On Android, PWA push notifications have worked for years without any restrictions. On iPhones, Apple added full support for PWA notifications, so the technology itself is no longer a barrier - push is available for PWAs regardless of phone type.
In EventApp, you send announcements about room or session time changes to all guests, selected groups or specific people. Message content is available in the app. Signed-in attendees who have enabled push also receive it as a notification on their phone.
On iPhone and iPad, the PWA must be added to the home screen. The user then enables notifications in the app and grants permission in the system prompt. With clear instructions on the welcome screen, attendees can complete this step without difficulty.
Offline mode
The entry QR code works without signal if the attendee opened the app and their code online before arrival, on the phone they use at the event.
When a traditional store app still makes sense
PWA works great in most cases, but it's not always the best choice. Consider a traditional store app when:
- You need advanced hardware integration - e.g., NFC badges, indoor navigation via Bluetooth beacons (BLE), or augmented reality (AR) features.
- Your brand requires store presence - some organizations treat the App Store and Google Play as part of their marketing strategy.
In practice, most conferences, trade shows, training sessions, and corporate events don't require any of these features. In EventApp, attendees vote live, fill in surveys, take a scored quiz and message each other in chat. And if you need something custom, it can be added without building an app from scratch. We build NFC features or your own store app as a separate service.
How to launch a PWA event app at your event
Launching a PWA event app is simpler than it seems. With the right platform, the whole process - from configuration to launch - takes no more than 24 hours, with no coding required.
- Choose a platform with built-in PWA support - look for a solution that handles all the technical setup automatically. Platforms like EventApp let you configure everything through a visual panel, with no programming.
- Add content and branding - upload your logo, set colors, add sessions to the agenda, venue maps, hotel info, surveys, and live voting. Matching the look to your event identity takes minutes.
- Share with attendees - generate QR codes for print materials, send the link in the registration confirmation email, or place it on the event website.
You can configure EventApp's standard modules in the admin panel, without developer accounts or store publication. See the full list of features for your event.
The app keeps working for at least 12 months after the event. Attendees can access the photo gallery, speaker presentations, and certificates - all in one place, no digging through email.
Frequently asked questions
Does PWA work offline?
The entry QR code works without signal if the attendee opened it online earlier on the same phone. The agenda, maps, materials and new content are fetched from the server, so they need a connection.
Does PWA support push notifications on iPhones?
Yes, on iPhone and iPad with iOS or iPadOS 16.4 or later. The user adds the PWA to the home screen, enables notifications in the app and grants permission in the system prompt.
What's the difference between PWA and an App Store app?
The main difference is access. A store app has to be found and downloaded, while EventApp opens straight from a link or QR code. The agenda, venue map, push notifications, surveys, live voting, scored quiz and chat all run in the browser and are included in the 3,000 PLN net price per event.
How long does it take to deploy a PWA for an event?
The EventApp base package can launch within 24 hours of our first conversation. Timing depends on configuration scope; integrations and custom features are agreed separately.
