Scale profitable installs, measured all the way to in-app revenue
Mobile user acquisition agency: Apple Search Ads, Google App Campaigns, Meta, TikTok, ASO, and post-ATT measurement powered by data.junto.fr.
Since ATT and the arrival of SKAdNetwork, then AdAttributionKit, most app advertisers have been flying blind: an install tells you nothing about its value, and in-app ROAS gets lost in probabilistic attribution windows. At Junto, we reconnect every channel (ASA, Google App Campaigns, Meta, TikTok) to what actually matters: LTV by cohort and the in-app event that drives revenue. data.junto.fr models your post-install cohorts, measures the true incrementality of each source, and benchmarks your costs against 350+ brands. The result: we scale budget where installs turn into paying customers — not where the ad platform's dashboard claims they do.

Our method
Our mobile acquisition method connects ASO, paid UA, and post-ATT measurement into a single data-driven loop.
1. UA audit and post-ATT measurement model
We map your install sources, your SKAN / AdAttributionKit setup, your MMP (AppsFlyer, Adjust, Branch), and your conversion value schemas. We pinpoint where attribution is lying and where in-app ROAS goes unmeasured, then set up the incrementality model in data.junto.fr. Without reliable measurement, scaling just means burning budget.
2. ASO and store conversion
We optimize your App Store and Play Store pages like a real landing page: high-volume keywords, screenshots, preview video, view-to-install conversion rate. ASO mechanically lowers the CPI of every paid channel, because every click you buy converts better.
3. UA channel activation
We roll out Apple Search Ads, Google App Campaigns, Meta Advantage+ App, and TikTok in parallel, each with its own job. For Expensya, this Google, LinkedIn, and Meta mix drove +80% installs and -60% CPA across three markets. Every channel launches with its own conversion value schema, never a generic copy.
4. LTV cohorts and in-app events
We stop paying for installs and start paying for users who are actually worth something. data.junto.fr builds your LTV cohorts by source, device, and campaign, and ties CPI to the in-app event that predicts retention and revenue (trial, subscription, first purchase).
5. Profitable scaling and creative
We scale budget where the cohort holds your target ROAS, managing creative continuously: on TikTok, Decathlon achieved 12x purchase performance and cut its cost per click to a third. Creative is the number one CPI lever on algorithmic ad platforms — we produce and test it in a constant stream.
6. Ongoing benchmarking and incrementality
Every month, we measure the true incrementality of your sources (geo-tests, holdouts), benchmark your CPI and ROAS against the 350+ brands in data.junto.fr, and reallocate. You steer on incremental value, not on the attribution your ad platforms report.
At Junto, we build profitable mobile acquisition machines, measured from install to in-app revenue.

Frequently asked questions about mobile acquisition, ASO, and post-ATT measurement.
How do you measure app ROAS since ATT and SKAN?
SKAdNetwork and AdAttributionKit only return an aggregated, delayed signal with no granular user value. At Junto, we combine your MMP, your conversion value schema, and data.junto.fr's LTV cohort modeling to rebuild an actionable in-app ROAS, then validate real impact with geo-based incrementality tests. You steer on incremental value, not the platform's raw attribution.
Which mobile acquisition channels do you run?
Apple Search Ads, Google App Campaigns, Meta Advantage+ App, TikTok — and depending on the product, programmatic and influencer marketing. Each has a distinct role: ASA captures store intent, Google App Campaigns scales volume, Meta and TikTok open up cold audiences. For Leocare, a 100% mobile neo-insurer, this kind of orchestration across 7 Social & App channels doubled the revenue generated.
Is ASO still worth it if I'm already running paid?
Yes — it's actually a multiplier. An optimized store listing raises the view-to-install conversion rate of every click, including the ones you pay for. The result: a lower CPI on Apple Search Ads, Google App Campaigns, and social ads, without touching your media budget. ASO and paid reinforce each other — they don't compete.
How do I know whether an install is worth anything?
An install is worth nothing until it's tied to an in-app event. In data.junto.fr, we build your LTV cohorts by source and device, and tie CPI to the event that predicts revenue (trial, subscription, first purchase). Then we scale only the sources whose cohorts hold your target ROAS.
Is TikTok a serious channel for an app?
When the creative and the targeting are right, yes. On TikTok, Decathlon achieved 12x purchase performance and cut its cost per click to a third. The key is a constant stream of creative production and clean measurement: without those, TikTok scales unqualified volume. With them, it delivers some of the most competitive CPIs on the market.
How long until installs turn profitable?
The first signals (CPI, install rate) show up within a few weeks; true profitability is judged on cohort maturation — so 6 to 12 weeks depending on your in-app cycle. We always start by making post-ATT measurement reliable, because scaling without trustworthy measurement just amplifies an invisible loss.
