TestFlight and Burstly will continue to be independent products. TestFlight remains a free service and optional paid features will be introduced in the future. TestFlight will continue to build the best developer tools and will include Burstly features only to improve product functionality (as in the case of adding revenue to TestFlight Live), and vice versa for Burstly products.
Surprising news that Test Flight was acquired by Burstly this morning. I am excited to see what comes from this.
Most interesting part is a new desktop app to manage everything.
Side note: if you are an iOS developer and are not using Test Flight, you need to be. So go sign up.
