I launched on Product Hunt and arrived at #5 Product of the Day. https://www.producthunt.com/posts/replica-2 The launch went overwhelming well for my expectations and I was featured in German, Netherlands and Spain News. This contributed to more than 100K Downloads over 4 days.
After some months of work. I was able to have a working MVP. From this step on I started building the app and preparing the marketing and launch. I was almost giving up due to technical challenges and the difficulty of the problem at hand. Glad I didn't.
From the users of my other app "TV Streams" I kept on getting asked to add Chromecast Support to be able to watch on the TV. While I added this to the app, some formats were still not compatible with the Chromecast device, looking around at the competition I couldn't find a good solution in the market.
