The install isn’t the win. Retention is.
App Marketing Services & Agency for Mobile App Growth
Most app budgets buy installs that vanish by the weekend — the average app loses roughly 90% of its users within 30 days. This lays out how app marketing actually works, so you win on onboarding, retention, and lifetime value instead of a vanity install count. You can’t buy your way out of a leaky retention curve. No pitch. Just the model.
What’s inside
Installs don’t compound. Retained users do.
An app isn’t an install count — it’s a loop. Someone installs, gets onboarded, hits a first win, comes back, and eventually pays. Break any stage and the rest leaks. Pour paid budget into the top of a leaky bucket and you rent users; fix the loop and each cohort is worth more than the last.
- One loop, not one number. Acquire, onboard, activate, retain, monetize — each stage feeds the next.
- The weakest stage caps the app. A great UA team can’t outrun a broken day-1 experience.
- Installs spend. Retention compounds. That’s the line between renting users and building a business.
Retention is the single most important thing for growth.

Ninety percent gone in thirty days.
The honest baseline: a 2015 analysis of 125M+ Android devices found the average app kept about 29% of users at day 1, 17% at day 7, and under 10% at day 30 — roughly 90% gone in a month.1 The best apps do far better; the gap between the average curve and the top-decile curve is the whole game. Move the sliders and watch the cliff.

The lesson isn’t “apps die.” It’s that the money is in bending the curve, not filling the top of it. retention curve · cohort analysis · retention-rate calculator
Value first, or one and done.
Roughly one in four apps is opened exactly once.2 The fix is rarely more features — it’s getting a new user to their first real win before you ask for anything. Apps that lead with value instead of a sign-up wall cut one-and-done use from about 25% to 13%.2 Pick a path and see the day-1 cohort split.
Lead with value — let people feel the payoff before the ask — and roughly 13% churn after a single session. A session-1 nudge toward the “aha” moment does most of the work.

Buy installs that pay back.
Paid user acquisition works when the value a user returns clears what the install cost — and clears it fast enough that you’re not financing growth forever. That’s three numbers: cost per install, how long users stay (your D30 retention), and what an active user earns per day. Set them and watch the payback move.
How it’s calculated
We fit a power-law decay curve to your day-30 retention, then sum the days a cohort stays active over a year:
Payback is the first day the running revenue per install clears CPI. Break-even D30 is the retention that makes LTV equal CPI at your ARPDAU (solved numerically). The power-law fit is RGM analysis, illustrative — a real model uses your measured curve and monetization ramp.

Half your installs start with a search.
Paid UA is only one faucet. Apple says about 65% of App Store downloads come straight from a search,3 so your store listing is the highest-leverage “ad” you own — and it’s free. App store optimization tunes the title, keywords, screenshots, and conversion of that page so organic installs compound while paid does the fast work.
- Rank for what people type.
Title, subtitle, and keyword field decide which searches you even appear in.
- Win the tap with the listing.
Icon, first two screenshots, and ratings drive the store-page conversion rate.
- Feed the loop back.
Retention and reviews lift store ranking, which lowers blended CPI on paid.
ASO and paid UA aren’t rivals — organic lowers your blended cost and paid buys the speed. We run them as one system. App store optimization services → · what ASO is
Measure cohorts, not calendar days.
App growth lives or dies on the pipeline that turns raw taps into a trustworthy number. In-app events flow through a mobile measurement partner, get reconciled against privacy-safe attribution (Apple’s SKAdNetwork and the AppTrackingTransparency prompt shape what you can see), and land as cohort retention, LTV, and ROAS — read by the cohort that installed, not by whatever happened this week.
Steer with attribution, prove cause with holdouts, plan with a media model — the same three-layer discipline, read by cohort. marketing analytics · incrementality testing · DAU/MAU calculator
The RGM app-growth loop.
We don’t start with media plans. We start with the leakiest stage — the one capping everything downstream — and fix that first. Then we run the loop: acquire deliberately, onboard to a first win, activate the habit, retain with lifecycle, monetize the retained, and turn the happiest users into the next cohort’s cheapest installs.
Pricing is custom to the work — flat, project, or a percentage, set by what fits the engagement. Judge any structure by its incentives: the fee should point at retained revenue, not just install volume. growth strategy · experimentation
Know what good
looks like first.
Anchors, not gospel. App retention and monetization vary wildly by category, platform, and year — so we label every figure with its source and date, and build your real numbers on your own cohorts. These are starting points for judgment.

- What is app marketing?
- The full discipline of growing a mobile app — onboarding, activation, retention, monetization, paid user acquisition, and app store optimization run as one loop, measured by cohort payback rather than install count.
- What does an app marketing agency do?
- It fixes the leakiest stage first (usually onboarding or day-1 retention), then runs paid UA, ASO, lifecycle, creative, and measurement together against one number — retained, paying users.
- Why does retention matter more than installs?
- The average app loses roughly 90% of its users within 30 days (Quettra/Andrew Chen, 2015), so installs poured into a leaky curve rent users; retention compounds cohort value and lowers blended cost.
- How is app marketing measured?
- By cohort: in-app events through a mobile measurement partner, reconciled against privacy-safe attribution (SKAdNetwork, ATT), read as retention, LTV, and ROAS by install cohort, steered with attribution and proven with holdouts.
- How do you choose the best app marketing agency?
- Pick operators who fix onboarding and retention before scaling spend, prove UA pays back by cohort, run ASO and paid as one system, and measure incrementality rather than raw attribution.
