What is a good cost per install for a mobile app?

There is no universal number — a good cost per install is one comfortably below the lifetime value of the users it brings in. The discipline matters more than the figure — most teams should target an LTV-to-acquisition-cost ratio of 3 or better before scaling spend. Costs vary widely by channel, geography, and category (games pay far more and buy far more installs than utility apps), so benchmark against your own LTV, not an industry average. Note that searching cost per install also surfaces unrelated economic data, so qualify the term with mobile or app when researching.

Is paid or organic acquisition more important?

For most apps, organic. Across MWM's catalog the median app gets 61.6% of installs organically, and the median organic-search share is 52.3% — meaning App Store search alone drives over half of installs for the typical app. Paid is a layer sized by your LTV math, not the foundation. Games are the exception — they buy aggressively (97% run paid UA, with a median 53% paid share) because their economics support it.

How do you lower your effective cost per install?

Three levers. Improve creative so click-to-install rate rises (better IPM lowers effective cost per install on the same spend, and rotating creative fights fatigue). Lean on organic — strong ASO and the organic uplift that paid campaigns generate lower your blended cost. And retarget or pursue lookalikes instead of always buying cold installs, since re-engaging known users is cheaper than acquiring new ones.

How much should I spend on user acquisition?

As much as your unit economics support and no more. If your LTV-to-cost ratio is 3 or higher, scale until efficiency drops or you exhaust the audience. Between 2 and 3, fix creative and conversion before adding budget. Below 2, do not scale — improve retention and monetization first, because spending more only amplifies a loss. Acquisition cannot outrun a leaky product.

What role does Apple Search Ads play?

It captures high-intent users at the moment of search, which is why it is a common first paid channel. Across the catalog about 34% of paid-running apps use Apple Search Ads, with a median 36% share of paid installs among those that do. It pairs naturally with ASO — you rank organically and defend or extend that visibility with paid placements on the same high-intent queries.

User Acquisition Strategies — How to Acquire App Users and Lower Cost per Install

The first thing the data overturns is the assumption that user acquisition means buying installs. Across MWM's catalog, the median app gets 61.6% of its installs organically, and 52.3% come from App Store search alone — meaning organic search drives more than half of installs for the typical app before a single ad dollar is spent. Paid user acquisition is real and 82.8% of apps run it, but for most it's a layer on top of an organic foundation, not the foundation itself.

This guide covers the acquisition mix, the math that caps what you can spend, and how to lower your effective cost per install. (Heads up: "cost per install" research also surfaces unrelated economic indices — qualify it with mobile or app.)

The UA equation: you can only pay for what you can keep

Acquisition is not a growth lever on its own — it's a multiplier on retention and monetization. The ceiling on what you can profitably pay per user is set by LTV:

If your LTV ÷ acquisition cost isn't comfortably above 1, more spend just loses money faster.

The standard bar is an LTV-to-CAC ratio of 3 or better before you scale. This is why the retention and monetization playbooks are also acquisition playbooks: every point of retention or ARPU you add raises the CPI you can afford, which unlocks channels and scale that were previously underwater. Acquisition cannot outrun a leaky product.

Measure it with ROAS by cohort and channel, and get install attribution right so you know which channel actually earned the user.

Channel 1 — Organic: the default majority

For most apps this is the larger channel, and it's the cheaper one.

App Store Optimization is the engine. Organic search is 52% of installs for the median app — that's the ASO surface. The full play is in The Complete Guide to App Store Optimization; the point here is that ASO is not a side project, it's your biggest acquisition channel.
Referrals and virality. A referral program and a healthy viral coefficient turn retained users into new ones at near-zero marginal cost — the compounding channel.
Store featuring and ratings drive organic spikes that paid can't buy.

Channel 2 — Paid: when the LTV math works

Paid UA is how you scale past organic once the economics support it.

Apple Search Ads captures high-intent users at the search moment — about 34% of paid-running apps use it. It pairs with ASO: rank organically, then defend and extend with paid placements on the same queries.
Social and video networks (the large paid platforms) drive volume; lookalike audiences extend your best users and retargeting brings back the lapsing more cheaply than buying cold.
Size it by category. The data is stark: games run paid UA at a 97.2% rate with a median 53% paid share, while content and utility apps run paid at 71 to 78% with only an 11 to 20% paid share. If you're not a game, paid is a minority of your mix by design.

Lower your effective cost per install

You don't only lower CPI by bidding less — you lower it by converting more from the same spend:

Creative is the biggest paid lever. A higher install-per-mille (IPM) means more installs per impression, which lowers effective CPI directly. Rotate creative to fight creative fatigue, the silent CPI inflator.
Harvest organic uplift. Paid campaigns lift organic rankings (more installs → better chart position → more organic). Your blended cost per install is lower than your paid CPI; manage to the blend.
Retarget before you re-buy. Re-engaging a known user is cheaper than acquiring a stranger.

The category lens

Category	% running paid UA	Median paid share	Median organic share
Game	97.2%	53.3%	39.5%
Media & Entertainment	78.1%	19.6%	66.7%
Education & Knowledge	74.4%	17.3%	66.4%
Social & Communication	73.8%	13.6%	71.5%
Lifestyle & Well-being	73.1%	12.8%	66.7%
Productivity & Tools	71.5%	11.3%	68.8%

Games buy growth; everyone else earns most of it organically and buys at the margin. Pick the playbook that matches your economics — copying a game's paid-heavy mix into a utility app burns money the LTV can't support.

Where to start

Compute your LTV-to-cost ratio first. Above 3, scale paid until efficiency drops or the audience thins. Between 2 and 3, fix creative and conversion. Below 2, stop scaling and go fix retention and monetization — the channels won't save unit economics that the product is leaking. Then build organic as the durable base and layer paid on top, sized to what you can keep.
