Every time I go to Mint.com on my iPad, there’s a banner at the top of the screen. Taunting me.

Yes, I do have the Mint app installed on my device. No, I don’t want to use it.

The Mint app only has a fraction of the features available on Mint.com. It’s really disappointing. For the most part, I like Mint as a service, but it’s a rare occasion that I open their app.

But I’m not here to talk about Mint specifically. What I do want to talk about is something broader. I want to talk about what makes something a “mobile” app.

Six or seven years ago, Mint would’ve been a great app. These were the days that mobile apps were considered to be almost a satellite experience. A limited, on-the-go sort of experience. All the big features were on your computer, where you did real work, and the mobile app just had a few small, key functions that you might want to do from your phone. Doing real work on a smartphone was for addicts and Crackberries. No normal person would want or need to do work from their phone, right?

No one thinks this way anymore.

In fact, the paradigm has completely reversed. Instagram is a prime example: Instagram is an app first, and a website second. “Second” might actually be too generous a word. For years, Instagram didn’t even have a web view. Now they do, but it’s only that: a view. You can’t post to Instagram from a desktop computer, you have to use their app. Mobile is king.

In just a few short years, the focus has completely shifted. Twitter just killed their Mac app. 93% of Facebook’s daily active users are on mobile. And I’m willing to bet that the numbers for 18-35 year olds are even higher. Mobile isn’t going anywhere. Get used to it.

Mobile is king.
