Reddit Ads for Mobile Apps: DIY or Hire an Agency? (2026)

You can run Reddit ads for mobile apps yourself if your mobile measurement partner (MMP) is connected, you can make creative that looks native to Reddit, and you can test for about 3 months. Hire an agency when your Reddit numbers don't match your MMP, when you want to scale, or when nobody has time for creative and comments. Here's how to decide.


When can you run Reddit ads for your app yourself?

DIY works when most of these are true:

  • Your MMP, like AppsFlyer, Adjust or Kochava, is connected to Reddit, so you can see installs outside Reddit's own dashboard.

  • You know what an installed user is worth to you, so you know what cost per install (CPI) you can afford.

  • You can make ads that look like Reddit posts: real screens, real photos and honest headlines, not polished app store art.

  • You can reply to comments on your ads. People ask about pricing, privacy and bugs, and someone has to answer.

  • You can test properly. In our experience, under about $6,000 over 3 months ($2,000 a month) rarely teaches you much.

When should you hire an agency for Reddit app ads?

  • Your numbers don't match. In one of our app campaigns, Reddit Ads Manager showed 32 installs while AppsFlyer counted 222. Judged by Reddit alone, the campaign looked like a failure. Details are in our app installs case study.

  • You want to scale. Bigger budgets break things fast if you don't know which communities and ads work.

  • iOS reporting confuses you. Reddit supports SKAdNetwork (SKAN) 4.0 for iOS, but reading SKAN next to your MMP takes practice.

  • Nobody has time for creative and comments. That's where most app campaigns win or lose on Reddit.

What does an app-focused Reddit ads agency do?

  • Connects Reddit to your MMP and checks that installs and in-app events come through.

  • Picks the right goal: App Installs to start, then App Event Optimization when you want users who sign up or pay.

  • Finds the communities where your users talk, split by iOS and Android when it matters.

  • Writes Reddit-native headlines and tests real screens against other formats. In our app test, real photos beat AI-made memes, and a headline that named a subreddit beat a feature-led one.

  • Replies to comments in a human voice.

  • Reports on installs, registrations and retention from your MMP, not just clicks.


What's new for app advertisers on Reddit?

Reddit is putting more into apps. Its app install revenue more than doubled year over year, according to its Q2 2026 earnings call. In May 2026 it added dual attribution in beta: Reddit's own numbers next to your MMP and SKAN data in one Ads Manager view. More measurement changes are on our Reddit ads roadmap.


DIY vs agency for Reddit app ads: what's the difference?

  • Cost: DIY is ad spend plus your time. An agency is ad spend plus a fee.

  • Speed: DIY means learning as you go. An agency skips the common setup mistakes.

  • Tracking: DIY works if your MMP is set up. An agency checks Reddit, MMP and SKAN numbers against each other.

  • Creative and comments: DIY needs someone on your team who gets Reddit. An agency handles both.


How much does a Reddit ads agency for apps cost?

Agencies usually charge a monthly fee, a percentage of ad spend, or a one-time project, and your ad spend goes to Reddit on top. With us, you can start with a one-time Reddit Ads Game Plan ($599) that maps your communities, creative and setup, or have us run it with Done-For-You management. Before you hire anyone, use our 12 questions to ask a Reddit ads agency.


Reddit ads for mobile apps: FAQ


Do Reddit ads work for mobile apps?

They can. In one month of app install ads, we got 222 installs at a $16.49 cost per install, measured in AppsFlyer. Results depend on your app, market and creative.


Which MMPs work with Reddit?

Reddit works with mobile measurement partners such as AppsFlyer, Adjust and Kochava. Connect yours before you launch, so you can judge results outside Reddit's dashboard.


Should I judge Reddit app ads by Reddit Ads Manager?

Not alone. Compare it with your MMP. In our case study, Reddit showed 32 installs while AppsFlyer counted 222.
