30+ Mobile Marketing Statistics: App Spend, Push & In-App Ads (2026)

The phone in your pocket is now the marketing channel. US adults spend roughly five hours a day on mobile, more than TV, desktop, and print combined, and they spend almost all of that time inside apps rather than on the mobile web. Every dollar a brand wants to put in front of a shopper in 2026 has to fight through a small glass rectangle, past an OS that hides the user's identity, into a moment measured in seconds.

The promo code is one of the few signals that still cuts through. A push with a unique offer code, an in-app banner that drops a deal into the cart, a mobile search ad that lands on a coupon page, a geofenced alert as a shopper walks past a store. Below are 30+ mobile marketing statistics we verified against primary sources for 2026, across seven themes.

Frequently Asked Questions

Mobile marketing in 2026 is no longer a channel inside a larger plan, it is the channel where most attention, most inventory, and nearly half of all e-commerce happens. Push, in-app ads, mobile search, and geofencing converge on the same small screen, and the promo code is one of the few signals that still ties a mobile impression to a checkout. At 99coupons.ai, that is the loop we live in: verified codes, mobile-first surfacing, so the deals shoppers see actually work when they tap to buy.
