And now, as with many companies in this space, he's breaking out his smarts for a wider audience.
Welcome to the App Store Competitive index and the Cost per Loyal User index.
Analyse this
Both are calculated on a monthly basis using the raw data Fiksu tracks in real-time so its clients can maximise their advertising spend when it comes to getting people to download free apps.
Taking them in turn, the App Store Competitive index provides an average for the number of daily downloads achieved by the top 200 free iPhone apps on the US App Store.
For July, the figure was 4.25 million downloads, compared to 4.51 million in June and 3.78 million in May.
The other index is really interesting however. The Cost per Loyal User index measures the cost of acquiring a loyal user - defined as someone who opens an app they've downloaded three or more times.
In July, this was $1.20, down compared to $1.27 in June, but up from $1.10 in May.
Fiksu comments that the decline from June to July could be due to the tailing off of incentivised downloads on iOS, which it says has reduced the ability of publishers to quickly gain rank through bulk downloads, but which delivers higher loyal user conversion rates at a lower net cost.
Data for the indices was sourced from 2.7 billion mobile app actions such as app launches, registrations and in-app purchases recorded by apps marketed via the Fiksu for Mobile Apps user acquisition platform.
