Launch and growth strategy
Whether you are launching in London or scaling globally, app growth needs an end-to-end plan. We set North Star metrics, define target cohorts, and map the AARRR funnel: acquisition, activation, retention, revenue, and referral. Then we build a testing roadmap across ASO, paid user acquisition, onboarding, and monetisation so spend scales only when cohorts hold. You get clear guardrails for CPI, CPA, payback period, and day-based ROAS rather than channel-by-channel guesswork.
AARRR funnel and cohorts
Define activation and retention benchmarks, then track cohort curves so acquisition decisions are tied to revenue outcomes, not only install volume.
Channel mix and budget rules
Allocate spend across ASA, Google App Campaigns, and paid social with clear scale rules, shifting budget based on LTV, payback, and ROAS by segment.
Creative and offer strategy
Align ad angles, store messaging, and onboarding offers so users see one consistent promise from first impression through first session and conversion.
How we run growth
We work as an integrated app growth pod: strategy, creative, paid media, and analytics in one rhythm. We set tracking, define cohort KPIs, then ship weekly batches of creatives and experiments across channels. Results are reviewed against retention and payback, not platform-reported vanity metrics. You get a shared backlog, fast execution, and clear scale decisions, without the delays of hiring or managing multiple suppliers.
- Weekly creative and UA sprints
- Cohort-based scale decisions
- One team across the funnel
ASO and store conversion
ASO is often the highest-leverage efficiency win because it improves conversion from every channel. We optimise App Store and Google Play listings using keyword research, metadata improvements, screenshot and preview video testing, and localisation where needed. We align store messaging with your ad angles so the promise in the ad matches the store page, reducing drop-off after click. ASO and Apple Search Ads work especially well together, with paid learnings feeding organic rankings.
Keyword and metadata mapping
Build a keyword plan by intent and competition, then optimise titles, subtitles, and long descriptions to improve discoverability without sacrificing clarity.
Store creative A/B testing
Test icons, first screenshots, and preview video hooks to lift store conversion rate, then roll winners across variants and priority markets.
Ratings, reviews, and trust
Improve review volume and sentiment with ethical prompts and timing, and reflect trust cues in store visuals to increase conversion on competitive keywords.
UA, retention, and revenue
We run paid acquisition and lifecycle as one system. On UA, we manage Apple Search Ads, Google App Campaigns, and paid social across Meta, TikTok, Snap, and other networks when they fit the audience. On retention, we build segmentation and messaging across push, in-app, email, and SMS using tools like Braze, Airship, or OneSignal. For monetisation, we test paywalls, pricing, and ad formats so revenue grows without hurting experience.
Performance UA with cohort targets
Optimise towards ROAS and LTV by cohort, not only CPI, so budgets scale when retention and monetisation hold across iOS and Android.
Lifecycle messaging and reactivation
Reduce churn with behaviour-triggered journeys, push fatigue controls, and win-back flows that re-engage lapsed users with relevant value and timing.
Subscription and ad monetisation tests
Test paywalls, bundles, and price points, and refine ad monetisation such as rewarded formats, so ARPU grows while protecting ratings and retention.
Measurement you can trust
App attribution is noisy, especially post-ATT. We set up measurement with an MMP like AppsFlyer, Adjust, Singular, or Branch and align it with platform reporting and SKAdNetwork constraints. We standardise event naming, cohort reporting, and dashboards so teams can see acquisition, retention, and revenue in one place. When budgets justify it, we use controlled tests and incrementality thinking to avoid scaling on false signal.
- MMP and SKAdNetwork alignment
- Cohort dashboards for decisions
- Incrementality mindset for scale
SEO that compounds, not a checklist
Organic growth is a mix of technical hygiene, content that earns clicks, and authority building that is genuinely deserved. We treat SEO as a product, with a backlog and a cadence, rather than a one-off project. Technical work covers crawlability, site architecture, Core Web Vitals, schema markup and index management. On-page work is driven by search intent and the real questions buyers ask at each stage. Off-page focuses on link earning through useful assets, partnerships and digital PR rather than spam. For example, for a B2B brand we might build a set of comparison pages for demand capture, a small research piece to earn links, and a library of problem-led articles that support sales calls. The outcome is more qualified traffic, better brand credibility, and lower dependency on paid media over time.

What does an app marketing agency in London do?
An app marketing agency typically covers the full funnel: awareness, installs, activation, retention, and revenue. That includes ASO, paid user acquisition, creative production, and analytics.
The best agencies also connect marketing to product outcomes by tracking cohorts, improving onboarding, and supporting lifecycle messaging. The goal is not just more installs, but better payback, higher LTV, and predictable growth across iOS and Android.
Which channels work best for app user acquisition?
Common channels include Apple Search Ads, Google App Campaigns, Meta, TikTok, and Snap. The right mix depends on category, geo, creative strength, and how quickly users monetise.
We usually start with a portfolio approach: capture high-intent demand through search and store channels, then scale discovery through paid social with rapid creative testing. Decisions are made using cohort ROAS and retention, not only CPI.
How do you improve App Store and Google Play ASO?
We improve ASO by aligning keywords, metadata, and store creatives with what users are searching for and what they care about. This includes keyword research, title and description optimisation, and creative testing on icons, screenshots, and preview videos.
We also focus on conversion drivers such as trust cues and review strategy, and we localise listings where it impacts demand. ASO is measured by ranking, CVR, and the organic lift it creates.
How do you track results after iOS ATT changes?
We set expectations upfront for what attribution can and cannot show post-ATT. We implement an MMP such as AppsFlyer or Adjust, align events and reporting, and account for SKAdNetwork constraints on iOS.
We rely more on cohort outcomes and blended reporting, and we use structured campaign setups to isolate variables. When budgets justify it, we recommend incrementality thinking so scale decisions are based on real lift, not noisy attribution.
What metrics matter most for scaling an app?
Install metrics alone are not enough. We focus on activation rate, retention curves, ARPU or ARPDAU, and cohort LTV. For paid growth, day-based ROAS and payback period are key to knowing what you can scale.
We also track funnel drop-off from install to first session to key actions, so onboarding fixes are prioritised. The point is to scale spend only when cohorts are healthy and monetisation is stable.
How do you increase retention and reduce churn?
Retention improves when users reach value quickly and are brought back at the right moments. We build lifecycle journeys with segmentation and behavioural triggers across push, in-app messaging, email, and SMS using tools like Braze, Airship, or OneSignal.
We also manage frequency to avoid push fatigue and use win-back messaging for lapsed users. Success is measured through retention cohorts and revenue per user, not vanity engagement.
Can you help with app monetisation and pricing tests?
Yes. We support monetisation by testing subscription paywalls, free trials, bundles, and pricing presentation, and by optimising ad monetisation when relevant. The goal is higher ARPU without harming retention or store ratings.
We run experiments with clear hypotheses and measure impact through cohorts. For ad-supported apps, we help assess formats such as rewarded placements and check the trade-off between revenue and experience.
What should we expect in the first 30 days?
In the first month, we prioritise foundations and quick wins: tracking and dashboards, baseline cohort reporting, ASO hygiene, and a structured creative testing plan. You should also expect early UA learnings and a clearer view of unit economics.
Meaningful scale comes after we validate cohort health and payback, so we avoid rushing spend. The aim is a system that compounds results, not a short-term spike followed by volatility.

Lifecycle marketing that increases LTV
If you only optimise acquisition, you end up paying more for the same customers. We build lifecycle systems that raise retention and expansion, using email, SMS where relevant, and CRM workflows that feel personal without being creepy. We set up segmentation based on behaviour and value, then design flows for onboarding, activation, replenishment, win-back and referral. In practice that can include RFM modelling for ecommerce, lead scoring for B2B, or product usage triggers for SaaS. We also help you capture first-party and zero-party data with preference centres and progressive profiling, so targeting stays resilient as privacy changes. When we ran a lifecycle audit for one team, we found revenue sitting in overlooked moments, like post-purchase education and renewal risk signals. The outcome is a healthier blended CAC and a marketing engine that keeps paying you back.
Measurement you can trust and use
Attribution arguments waste time and block good decisions. We set measurement up so it is good enough to guide spend, creative and roadmap choices, and we are honest about what is knowable. Tracking work can include GA4 hygiene, conversion event design, server-side tracking where appropriate, and consistent UTMs. Reporting lives in a real-time dashboard, with views that match how you run the business, such as channel performance, funnel conversion, cohort retention and creative learnings. We also use incrementality thinking where it matters, like geo holdouts or controlled tests for bigger budget shifts. For example, if brand search rises after a video push, we look at the whole picture rather than declaring victory based on last click. The outcome is faster iteration and fewer surprises in board meetings.
Operating rhythm, SLAs and ways of working
Good marketing is mostly good operations. We set a working rhythm that keeps delivery moving and prevents strategy decks from becoming a comfort blanket. You get a named lead, specialist channel owners, and access to top-tier US and UK talent, scaled up or down based on your needs. We agree response times, approval flows and who owns what across creative, landing pages, tracking and budget changes. Campaign planning happens in short cycles, with clear priorities and a shared backlog, so work does not disappear into a black box. We also help your internal stakeholders, like product, sales and finance, stay aligned with what marketing is doing and why. The outcome is a calm, consistent cadence, less context switching, and a team that behaves like your internal staff while staying on a monthly rolling basis.
