While most mobile founders chase viral apps, Readdle has been quietly building a suite of utility tools that print cash.
With over $25M/year in revenue and 5 apps generating $200K+/month, this Ukrainian app studio has mastered sustainable App Store growth.
Here’s how they did it.
2 Flagship Apps Drive 50%+ of Revenue
Readdle has 8 active apps.
But two of them – PDF Expert and File Manager – account for the majority of their revenue.
They’ve focused on evergreen utilities that dominate long-term search intent: file handling, scanning, PDF editing.
This gives them high retention and recurring demand.
ASO: Front-Loaded Keyword Titles
Readdle uses a smart ASO naming convention:
They start app titles with category-defining keywords like:
-
“PDF”
-
“Documents”
-
“Scanner”
Because most of their apps launched over a decade ago, they likely secured top rankings before these keywords got competitive.
Now, they rank in the top 3 for 1,000+ keywords per app, including:
-
“document”
-
“pdf editor”
-
“documents app”
-
“calendars”
🚀 Turn your app from “Launched” to “Growing” in just 3 weeks.

Review Velocity → Ranking Velocity
Their top apps have massive review counts:
-
PDF Expert – 4.7★ from 207K+ reviews
-
Documents – 4.8★ from 608K+
-
Scanner Pro – 4.9★ from 308K+
These reviews fuel their ASO flywheel:
More ratings → Better rankings → More downloads → More ratings
It compounds over time.
SEO: A Rare Second Channel
Unlike most mobile app studios, Readdle has serious web presence too.
Their site for PDF Expert pulls in 233K visits/month – with 58% from organic search.
This gives them another scalable, intent-driven user acquisition channel – and reduces paid CAC over time.
Paid Ads: Not Just Meta + TikTok
Readdle is active across all major ad platforms – but they go heavier on Google Ads, where most utilities perform better.
-
500+ Google ads in the last 30 days
-
Meta + TikTok video ads are mostly short-form videos.
If you want to know their target audience, check for “EU Transparency” label in the ad. Platforms like FB/TikTok are required to disclose ad targeting in the EU.
This gives you a clear picture of who they’re targeting (Age, Gender, Location).
