Ad spend is significantly up in the new Singular Quarterly Trends Report for Q2 2025, but not for the Shopping category in the United States, where we’re seeing a massive slump that correlates with the new tariffs on China and other nations.

Ad spend changes: quarterly trends

There has been a ton of activity in the mobile ecosystem in early 2025. A few of the biggest changes include Apple being forced to open up third-party payments and tariffs rocking not just the offline world, but digital commerce as well.

Here are some of the key quarterly trends ad spend changes we see.

Note: this is normalized based on the year-ago quarter, so 100% is flat, under 100% is a drop, and over 100% is an increase.

global ad spend changes 2025

Mobile game user acquisition spend is down, as is Shopping or e-commerce.

But by isolating US-only data, we can see that e-commerce app user acquisition ad spend is down massively: 44.9% year-over-year and 45% quarter over quarter. Again, this is normalized to the year-ago quarter:

US retail ad spend down tariffs

This makes sense, as others have noted. There are fewer dollars being pumped into retail app growth:

Temu dramatically reduced — and eventually stopped — spending on Google Shopping ads between April 9 and 12, 2025. Shein is following a similar pattern, having cut its Google Shopping ads investment on April 15.

In other words, Shein and Temu and others dropping ad spend because of tariffs and the revocation of the “de minimis” rules that exempted lower-value individual purchases from tariff impact is a real thing. Retail app user acquisition spend dropped massively this past quarter.

Overall ad spend is up though, especially Entertainment and On-demand

However, there are some highlights where ad spend is significantly up.

Fintech apps as well as the On-demand, Travel, Entertainment, and Education categories saw a boost in ad spend. The biggest was Entertainment, where ad spend more than doubled year over year. This is not shocking if you saw our recent top 10 entertainment apps post for key countries such as USA, Brazil, Japan, India, Germany, UK, and Korea: there’s an intense battle for subscribers here.

Education did as well, but it’s a much smaller category in terms of app installs and user acquisition spend.

Spend on On-demand app marketing was up 56% year over year: also impressive after years of growth already.

Overall, ad spend by Singular customers was up 40.3%, an impressive jump.

Hottest app and game categories

Year over year, Match and Puzzle games grew over 150% in popularity on Android. On iOS Action, Educational, Card, and Simulation games grew over 150%.

Interestingly, gambling games grew over 136% on iOS.

There’s an interesting dichotomy between Android and iOS in terms of most popular app categories right now.

  • Android: On-demand apps rule
  • iOS: Entertainment apps are tops

On-demand and travel are second and third on iOS; Entertainment is second on Android.

Plus, all the metrics updates

We’ve got the latest quarter trends data on ATT acceptance by vertical, plus global trends on CPI, CTR, CPM, and IPM.

TLDR: it’s getting more expensive to find new mobile app users.

We also break down a lot of these metrics by vertical and geo, focusing on the following regions:

  • China
  • Japan
  • Rest of world
  • Tier 1 East: Korea, India
  • Tier 2 East: Taiwan, Indonesia, Turkey, Thailand, Philippines
  • Tier 1 West: Canada, France, Germany, UK
  • Tier 2 West: Australia, Mexico, Brazil, Spain, Italy, Netherlands, Poland
  • United States
