SaaS Mobile-Responsive UX Checklist
Most SaaS products are built desktop-first. This checklist ensures your product works well on smaller screens without a full redesign.
This checklist covers five areas where SaaS products most commonly break on mobile: navigation, touch targets, data tables, forms, and typography.
Mobile UX Checklist
Navigation
- Collapse sidebar to hamburger menu below 768px
- Use bottom navigation bar for primary actions on mobile
- Ensure all dropdown menus are scrollable on small screens
Touch targets
- Minimum 44x44px tap targets for all interactive elements
- Add 8px+ spacing between adjacent tap targets
- Increase button padding on mobile breakpoints
Data tables
- Enable horizontal scroll for wide tables on mobile
- Consider card-based layouts for tables under 4 columns
- Add sticky headers so column labels remain visible during scroll
Forms
- Stack form fields vertically on mobile
- Use native input types (tel, email, date) for mobile keyboards
- Show validation errors inline, not in a toast that covers the keyboard
Typography and spacing
- Minimum 16px font size for body text (prevents iOS zoom)
- Increase line height to 1.6+ on mobile for readability
- Use dynamic spacing with clamp() for responsive gutters
FAQ
Should SaaS products have a mobile app?
Not necessarily. A well-optimized responsive web app often suffices. Build a native mobile app only when you need push notifications, offline access, or device hardware features that the web cannot provide.
Which breakpoints should I use?
For most SaaS products: 640px (mobile), 768px (tablet), 1024px (desktop), 1280px (wide). Test with real devices, not just browser resize.
How do I handle complex dashboards on mobile?
Prioritize the 2-3 most important metrics. Stack cards vertically. Let users swipe between dashboard sections instead of showing everything at once.
Key Takeaways
- Use a checklist covering navigation, touch targets, data tables, forms, and typography.
- Minimum 44x44px tap targets and 16px body font size are non-negotiable on mobile.
- Responsive web apps often beat native mobile apps for B2B SaaS unless you need offline access.
- Test on real devices, not just browser resize — touch behavior differs from mouse behavior.
