SurveyHeart
A survey app scaled past 10M downloads across Android and iOS.
The story
SurveyHeart was already growing fast when we took over mobile engineering. The Android app was a large Java codebase showing its age, and there was no iOS app at all.
We launched iOS from scratch and shipped it to the App Store, then led the migration of the Android codebase from Java to Kotlin while the app kept growing, with no downtime for users.
The result is an app that crossed 10 million downloads and stayed fast doing it. This is the scale experience behind every HelloVibe build.
