Top 21 App Marketing Agencies for Growing App Installs

Creator-Led App Acquisition

For Jodel, House of Marketers generated 85,644 installs at a reported €2.29 cost per install, with €196,521.46 spent over three to four months. The campaign combined more than 60 TikTok creators with paid distribution across Germany, France and Sweden.

That gives app buyers something concrete to examine: a named product, defined markets, campaign duration, spend and acquisition volume. It supports our inclusion for teams that need creator-led advertising to introduce an app and expand acquisition. The public case does not quantify retention improvement, so it should not be treated as proof of long-term user value.

Phiture offers one of the clearest examples here of work after the download. In its Headspace retention case, users receiving the tested campaigns had 109% higher week-one retention than the control group, alongside 49% more paid conversions within one day on average.

The work combined in-app messages, push notifications and email through Braze, including links into relevant meditation content. The 109% figure is a relative improvement against control, not a claim that 109% of users stayed, and it applies to campaign recipients rather than every Headspace user.

That makes Phiture particularly relevant when acquisition is functioning but people fail to find value or return. Ask which user behaviour the proposed intervention should change and how a comparison group will help establish whether it worked.

ConsultMyApp reports 2.4 times as many organic installs in three months for Tide, alongside a 47.6% reduction in Apple Search Ads cost per install. The programme combined store optimisation with paid search, including keyword, creative and ratings work.

The appeal is coordination between the two routes into the store. The figures are not interchangeable: organic-install growth measures volume, while paid CPI measures acquisition cost. Neither establishes how many people became active business-banking customers.

CMA is a relevant candidate when app-store search is central to the acquisition plan. Ask for brand and non-brand reporting and how the team will examine overlap between paid and organic activity. Otherwise, a campaign can look efficient while receiving credit for people who were already on their way.

For Wordling by Joyglitch, AppAgent reports tripling monthly US installs while increasing media spend 2.5 times. The work combined user-acquisition management, app-store optimisation and modelling of user value.

Reading the spend alongside the installs changes the story. This is evidence of expanding acquisition, not tripling efficiency at a fixed budget. The case is especially relevant to mobile-game teams deciding how far to increase spend while monitoring the value of new players.

Ask how the agency’s value predictions are checked against later player behaviour and which payback period determines the spending limit. The confidence to stop increasing a budget can be as valuable as the ability to spend it.

REPLUG’s PhotoSì case shows why “more visibility” needs a precise definition. Over two months, the agency reports 413% greater iOS main-keyword visibility in Germany, while the conversion rate of German iOS organic traffic more than doubled. The work combined store creative and metadata changes, with different results in Italy and across Android.

The case supports REPLUG for localisation and store-conversion work, not a blanket promise to quadruple downloads. Its useful lesson is the separation of being found from persuading someone who arrives. Request that same separation in reporting, broken down by country and operating system. One strong market should not conceal a weaker one in an international average.

AdQuantum’s Doorman Story case, published in January 2021, reports 2.5 million installs in six months, supported by more than 1,100 creative assets and distribution across several advertising platforms and networks.

The case demonstrates the scale of the production and media operation behind a mobile-game acquisition programme. Its age matters: it is a historical delivery example, not a current CPI benchmark. The public install total alone also cannot establish profitability.

Consider AdQuantum for a brief requiring sustained creative production and paid acquisition. Ask how many genuinely different concepts the proposed output contains, how winners are selected and what revenue period is used to assess payback. Hundreds of minor edits are not hundreds of new ideas.

Pixated’s Telegraph case reports 1,011% growth in app downloads and 215% growth in paid subscriptions in the first three months. Its account describes advertising audits, audience and keyword work, and subsequent optimisation for in-app conversions.

The subscription result makes this particularly relevant to publishers and paid-content apps: the work is evaluated beyond attracting a download. The case still does not establish subscriber retention, refunds or net customer value, and the starting volumes should be requested before interpreting the percentage increases.

For a subscription brief, ask Pixated to connect campaign reporting to the same subscription records used by your commercial team. The valuable comparison is the cost of acquiring a customer who stays, not simply the cheapest first payment.

Digital Performance and Conversion

RichClicks publishes measurable commercial work, but the medium matters. Its Arti & Mestieri case summary reports an 86.29% revenue increase around a Shopify migration and conversion work. That concerns an ecommerce website, not an app-install campaign.

The agency’s broader digital offering may be relevant to businesses managing both web and app journeys. The reviewed case does not establish app-acquisition performance, however. Ask for a mobile-specific example with store, advertising and in-app data before adding it to a dedicated app shortlist. A strong result in an adjacent discipline is a reason to ask a better question, not skip it.

Favoured’s WAC case follows the journey further than an install report. For the shift-management and money-management app, the agency reports improving install-to-registration conversion from 60% to more than 80%, alongside store and advertising work.

That matters because better acquisition can come from wasting fewer of the users already arriving. The case describes creative testing, app-store changes and onboarding improvements; its lowest reported CPI is not a campaign average and should not become a forecast for another app.

Favoured is worth considering when the brief spans the ad, the store page and registration. Require a clear division of responsibility with your product team. Registration remains an intermediate event, so include the first useful action and later activity in the review.

Acquired by Jellyfish

This is a legacy name, not a separate agency buyers should automatically put on today’s invitation list. Jellyfish announced its acquisition of The ASO Co in October 2018, bringing its app-store optimisation and mobile expertise into the larger business.

The ownership history establishes where to direct an enquiry; it does not establish the performance of a current campaign. Ask Jellyfish to identify the team responsible for app-store work and provide a recent case for your app category and market. The relevant purchase is the service available now, not the independent company described in an old listicle.

Adsbalance’s published client cases include 153% of the daily-active-user target achieved for Lazada, against a stated target of 360,000, and 6,000 installs a day for Rush Royale. The examples identify push and banner distribution.

That gives buyers named evidence beyond a general claim about premium users. The public summaries still omit important context, including campaign dates and the precise basis for measuring active-user contribution. Lazada’s figure describes achievement against a target, not a 153% increase in its total user base.

Consider Adsbalance when evaluating additional acquisition or re-engagement distribution. Before launch, settle which user actions are payable, how existing users are separated from new ones and how traffic quality will be checked. Volume is meaningful only when the definition survives inspection.

The original entry’s identity and performance claims remain unverified. It describes a business launched in 2019 without providing a clear company identifier or named app result. This review could not confidently match that description to the intended agency.

There is published app-store guidance under the SOZO name, but guidance is not campaign evidence and a shared name does not resolve company identity. Do not use this entry as a results-backed endorsement until the business and its relevant work are confirmed.

Nara Media’s published marketplace profile includes a Deliveroo client statement describing support for expanding paid-social activity, creative and reporting. It establishes a named client account of the working relationship, rather than merely a logo.

The reviewed evidence does not provide a client-specific numerical result and period sufficient for a comparative performance claim. Nara is therefore a candidate to investigate for paid acquisition, not a verified winner on cost or user quality. Request a current case that follows spend through to the action your business earns from, such as a first order, and confirm which team would run the account now.

Redbox Mobile’s current offering includes app-store creative, Apple Ads and other app-acquisition services. Its homepage reports an 87% install uplift for a driving-test app, but the public summary reviewed here does not name that client.

The reported result is a lead for further investigation, not named campaign proof. Redbox is relevant to a store-led acquisition discussion; request the underlying case, period, baseline and paid-versus-organic split before using the percentage in your business case. Also distinguish technology access from agency execution in the proposal. A platform and a team responsible for interpreting its results are different purchases.

Indiespring’s MORE THAN Smart Wheels project concerns rebuilding a telematics app: cross-platform development, a revised interface and more reliable journey tracking. That is useful evidence for an insurer or service business whose product experience needs attention.

It is not evidence of a paid acquisition campaign. Consider Indiespring when the growth problem may sit inside the app itself, then separate development from marketing in the statement of work. A successful rebuild can remove reasons for customers to leave; it does not, by itself, show that an agency can acquire the next thousand customers at an acceptable cost.

Edge360 Limited’s company profile describes app marketing, app-store optimisation, mobile creative and paid-media services. That suggests a potentially broad delivery brief, but breadth is not proof that each discipline has produced useful outcomes.

No named, quantified app campaign was established in this review. Require one before comparing Edge 360 with the results-backed entries. For a multi-channel acquisition proposal, pin down where the ads will run, which traffic sources are permitted and how newly acquired users will be assessed after installation. “Full service” should resolve responsibility rather than blur it.

This entry needs identity verification before it can support a recommendation. The original article describes Atomic and a partnership with Yonder, but it does not identify a website or a named app campaign with measurable results. This review could not reliably connect that description to one current agency.

We have not assigned the work of another Atomic-branded business to this entry. Establish the contracting company and ask it for a relevant acquisition case before spending time on a full proposal. A recognisable name is not enough to establish whose experience you are buying.

The original BlueOrange entry describes app-store and paid-search work, but this review could not verify the agency’s identity and cited client relationships through a sufficiently clear primary source.

That leaves a material gap, not an invitation to fill the paragraph with promises. We cannot substantiate a results-based recommendation or attach another agency’s publishing-sector case studies to BlueOrange. Confirm the business, current team and at least one named app result before treating it as a live candidate.

Mndwrk’s published SICXS materials describe a customer-experience and technology proposition spanning CRM, automation, commerce and integrations. That is more specific than the original article’s promise of everything from development through launch and marketing.

This review did not establish a named app-acquisition campaign with measurable results or confirm the current delivery arrangement. Treat the entry as a technology-services lead requiring further verification. Before including it in an acquisition pitch, establish which business would contract the work and whether it would actually own media, creative testing and post-install measurement.

The original shortlist associates Envision Digital with Appysalons, Freeze Debt and SportsBroker. This review did not locate sufficiently clear primary campaign evidence to verify those relationships and their outcomes, or confidently establish the current delivery business.

The name is not distinctive enough to borrow proof from another Envision-branded company. Before retaining it in an active procurement process, obtain the current website, contracting entity and a relevant client reference. Until then, this entry cannot support a claim about superior acquisition or conversion performance.

Door 105 has a named client account worth reading, but it concerns development. In a 2019 interview published by Clutch, Dolly Yourself’s founder describes an iOS app built with booking, provider filtering and payment functionality, and praises its usability and the team’s communication.

That is client testimony about building and launching an app, not a quantified acquisition campaign. A buyer seeking product development can investigate the example and confirm current availability. A buyer seeking more installs should ask for separate marketing evidence. The two engagements require different deliverables, different budgets and different ways of deciding whether the work succeeded.
