1. Website and Mobile App: Two Different Choices
When starting to develop a digital product, the familiar question is usually: "Should I build the website first or the app first?" In reality, each platform serves its own purpose and suits different groups of users.
2. Pros and Cons of Each Platform
Website
Advantages:
No installation needed — just a browser to use it
Optimized for SEO, making it easy to reach users through Google
Well-suited for landing pages, management systems, B2B sales, blogs, etc.
Disadvantages:
User experience isn't as smooth as an app
Limited ability to leverage hardware features like the camera, push notifications, etc.
Mobile App
Advantages:
Smoother, more user-friendly experience
Supports advanced features: location, camera, push notifications, offline storage, etc.
Better user retention if the app is useful and used regularly
Disadvantages:
Requires downloading and installing → a barrier for new users
Costly to build for multiple platforms (iOS & Android) and requires frequent updates
3. When Should You Choose Both?
Many startups initially choose to build the website first to test the market, then expand into mobile once they have a stable user base. However, if your product:
Targets everyday users who frequently use their phones
Has features that require the camera, GPS, or push notifications
Needs to retain users through a personalized experience
👉 Then rolling out both a website and a mobile app in parallel will help increase your reach and your chances of success.
4. A Real Story from a TJZenn Client
One TJZenn client in the education sector initially only had a website for online learning. After 3 months, they discovered that over 80% of users were accessing it via mobile phones. The TJZenn team built them a mobile app as well, and as a result, consistent study rates increased by more than 40%, with a clear rise in positive user feedback too.
