Do you need an app, a web app, or both?
"Should we build an app?" is one of the first questions founders ask — and it often means three different things: a mobile app, a web app, or both. Here's how to decide what you actually need.
Web app
A web app runs in the browser — no download, works on any device with a link, and updates instantly for everyone. It's usually faster and cheaper to build and reach users with. The trade-off: less access to phone features and no icon on the home screen (unless you make it a progressive web app).
Mobile app
A native mobile app lives on the phone, with full access to device features (camera, GPS, notifications), the best performance, offline use, and a presence on the home screen and in the app store. It costs more to build and maintain, and users have to download it — a real barrier for some products.
How to choose
- Need the widest reach, fastest and cheapest? Start with a web app.
- Need device features, offline use, or daily engagement and notifications? A mobile app earns its cost.
- Both? Common at scale — but usually start with one and add the other when there's a clear reason and budget.
Frequently asked questions
Is a web app cheaper than a mobile app?
Usually yes — one build reaches all devices via the browser, with no app-store process. A native app costs more to build and maintain.
Can a web app feel like a real app?
Yes — a progressive web app can be installed to the home screen, work offline and send notifications, closing much of the gap with native.
Should I build both at once?
Rarely at the start. Build one, learn from real users, and add the second when there's a clear reason and the budget to maintain both.
