You're misreading that statement. Downloading an app is not difficult, _getting_ people to download one is.

I personally don’t have much problem with the 100+ apps on my phone, but really it’s an app graveyard. I use maybe 10 regularly. I’ve also cut social media apps from my phone due to battery usage and privacy violations.

Downloading an app is more personal, phone storage space is still a premium for many people. App devs don’t seem to care at all how big there app is. We yell at at web devs when their page is >1mb. I’ve tried downloading simple apps whose size are 400mb, what the hell are they doing? If I can visit their site that’s 1mb or download their app that’s 400x, maybe I’ll just visit the site and be on with my day.

You’re on a web page. You can either do what you need or tap the install link, approve the install, wait for a huge download, find and open it, wait for it to initialize, authenticate in the app, and then find whatever you were doing. If you use this all the time it’s amortized over heavy usage but the vast majority of business apps are not, and every study I’ve seen shows people falling off at each of those stages.

Downloading apps is not difficult but it's difficult to get people to download apps.
