Key takeaways

  • Fix your store page first. Every install channel, free or paid, converts through it.
  • Compare channels by cost per retained user, not by cost per install.
  • Incentivized installs work best when you pay for a first in-app goal, not for the download alone.

Start with what an install is worth

Getting installs is not hard. Getting installs from people who open the app again next week is. Before you choose a channel, write down two numbers: what an average new user brings you over a period you trust, such as 90 days, and the most you are willing to pay to get one. Those numbers decide which of the methods below make sense for you.

If you are not sure how to estimate them, CAC vs CPA vs LTV and What is CPI? walk through the math with examples.

1. App store optimization (organic)

App store optimization, or ASO, is to app stores what SEO is to search engines. Many people find apps by searching the store or browsing its charts, so your store page is both a search result and a sales page. It is also where every paid channel sends people, which makes it the first thing to fix.

  • Title and subtitle. Say what the app does in plain words, and include the phrase people actually search for.
  • Keywords and description. On the App Store, use the keyword field fully. On Google Play, the description is indexed, so describe real features in natural sentences.
  • Icon and screenshots. The first two or three screenshots do most of the work. Show the core benefit, not the settings menu.
  • A short preview video if your app is easier to understand in motion.
  • Ratings and reviews. Ask happy users for a rating at a good moment, such as after a success, using the official in-app review prompts. Never pay for ratings or reviews. Both major stores prohibit it and can remove the app.
  • Localization. A translated store page in the languages of your target countries often lifts installs more than any ad.

ASO is slow and cumulative. It rarely brings a launch spike on its own, but it lowers the cost of every other channel because more visitors to the store page become installs.

2. Other free and low-cost channels

  • Your website and email list. Add store badges, deep links, and a smart app banner so existing visitors can install in one tap.
  • Communities. Forums, subreddits, Discord servers, and groups around your niche. Contribute first, and share the app only where the rules allow it.
  • Product launch sites and app review blogs, especially for a first release or a major update.
  • Referral programs. Reward users who invite friends, with a reward both sides receive after the friend actually uses the app.
  • Cross-promotion if you already have other apps or partners with a similar audience.

Paid user acquisition, or UA, is where most apps get volume. The main options in 2026:

ChannelHow you usually payGood for
App store search adsPer tap or per installPeople already searching for an app like yours
Social app campaignsPer impression or per click, optimized for installsBroad reach with strong creative and interest targeting
Search and video network app campaignsPer install or per in-app action, mostly automatedScaling once you know which events matter
In-app ad networksPer install, often with video or playable adsGames and apps whose users also play mobile games
InfluencersFlat fee or per installApps that are easy to show in a short video
Offerwalls and rewarded tasksPer install or per completed in-app goalFast volume and early ranking, with a clear goal to reach

Prices vary enormously by country, platform, and category, so treat any published average only as a rough reference. As a general pattern, installs cost the most in high-income markets and on iOS, and much less in large lower-income markets. Tier 1, 2 and 3 countries explains why.

4. CPI and CPE campaigns

With a CPI campaign, you pay a fixed price per install instead of paying for impressions or clicks. That moves some of the risk to the channel, but it creates a new one: a network paid per install is rewarded for installs, not for users. Two ways to protect yourself:

  • Pay for a deeper event where you can. A cost per engagement, such as finishing the tutorial or reaching level 5, costs more per result but filters out people who install and never open the app again.
  • Measure what each source brings after the install, not just the count. The next section shows how.

5. Incentivized installs, done right

Incentivized installs come from users who receive a reward, such as points, coins, or in-game currency, for installing an app and often for reaching a goal in it. They are fast and usually cheaper per install than non-rewarded sources, which is why they are often used at launch or to push an app up the store rankings for a while.

They also have a reputation for poor retention, and it is deserved when the task is “install and open”. A user who wants the reward will do exactly that and nothing more. The fix is to design the task so the reward lines up with real use:

  • Pay for a first goal, such as finishing onboarding, creating a profile, or reaching a level, not for the download.
  • Pick a goal that shows the value of the app, so users experience why they might keep it.
  • Limit the audience to the platforms, devices, and countries your app is built for.
  • Never reward ratings or reviews. This breaks app store rules.
  • Judge the source by retained users, not by the price of one install.

Incentivized traffic explained covers when rewarded users are a good fit and when they are not.

One option to test: Sharklio task campaigns

A Sharklio task campaign can ask users to install your app, reach a first goal you choose, and send proof such as a screenshot of that goal or their in-app username. You set a bid per country, limit the campaign to mobile and to Android or iOS, and pay only for completions you approve. Sharklio is launching soon, and advertiser accounts are opening country by country, so campaign creation may not be available where you are yet. Create your Sharklio account to be ready when it opens.

6. Measure retention, not installs

Every install channel should be judged by the same few numbers, split by source:

  • Day 1, day 7, and day 30 retention: the share of new users who open the app again after one day, a week, and a month.
  • Activation rate: the share who reach the first real use of the app, such as a finished tutorial or a first saved item.
  • Revenue per install after 7 and 30 days, from purchases, subscriptions, and ads.
  • Cost per retained user: spend divided by users still active on day 7. This often ranks sources very differently from CPI.

Example with sample numbers

Source A brings installs for $0.40, and 10% of them are still active on day 7. Source B costs $0.90 per install, and 30% are active on day 7. Per retained user, A costs $4.00 and B costs $3.00. The more expensive install is the cheaper user.

To measure this, use your app analytics tool or a mobile measurement partner, and give every source its own tracking link or campaign name. With rewarded tasks that are checked by proof rather than an attribution SDK, ask for something you can match on your side, such as the in-app username, so you can follow those users in your own data.

Watch for fraud warning signs too: installs that never open the app a second time, many installs from the same few device models, or installs that arrive seconds after a click. Ad fraud and bot traffic covers the patterns.

A simple plan for a small team

  1. Fix the store page and add store links everywhere you already have an audience.
  2. Pick two paid sources that fit your app and your budget. Advertise on a small budget helps if money is tight.
  3. Run each with a small, equal budget for a week or two, in a few countries you understand.
  4. Compare cost per retained user and revenue per install, not CPI.
  5. Scale the winner, keep testing new creatives, and review your numbers every month.

If your app has a website, the same thinking applies to web visits. How to get website traffic covers that side.

Frequently asked questions

What is the fastest way to get app installs?

Paid channels, especially CPI campaigns and rewarded offers, bring installs the fastest. Speed is only useful if those users stay, so pay for a first in-app goal where you can and measure retention by source.

Are incentivized installs allowed?

Rewarding users for installing and using an app is a common, accepted form of advertising. Rewarding ratings or reviews is not, and both major app stores prohibit it. Check the current policies of the stores and networks you use.

How much does an app install cost?

It depends heavily on the country, platform, and category. Work out the most you can pay from what a user is worth to you, rather than aiming for an industry average.

Can I get app installs for free?

Yes, through app store optimization, your own website and email list, communities, and referrals. These are slower than paid channels but keep working over time.
