After launching our app on iOS Testflight we had invited people to join the alpha and test our app. This was quite the challenge as we only had the iOS version out, so no Android version at that time. In addition to that Testflight itself was quite the user churner. People had to install it first before installing the app. Even some friends didn't want to bother with the whole process and needed a lot of convincing to try it out. We still managed to gain a hundred users despite all the hurdles! 🎉
