A lot of people feel that websites and apps may be old news in favor of “landing pages” or funnels that add a deeper experience beyond the 1st page.
Funnels are ultimately websites.
Within marketing there are many reasons to use websites or apps.
Websites should serve a purpose, they shouldn’t simply be to check a box.
What value can you add?
Is there are reason to make a dedicated app that would add benefit beyond a web app?
These things all depend on priorities, creativity, and resources.
At bare minimum, every business must have some series of websites that support the overall marketing funnel.
