[Composables.co](https://composables.com/index.md) contains short and sweet screencasts for Android Developers. The site contains both courses and lessons. Each lesson is usually 2 min long and it can be part of a course.

They cover various topics of Android development such as Jetpack Compose, testing, architecture, etc. There is a lot of content already on the website and more content is coming in frequent intervals (aiming for weekly releases).

That is the vision I have for this startup. The site already contains a lot of content, but not everything is there yet. For this to become a reality and to continue making such content, I need early adopters to support the project.

I am currently running a special early bird offer for $ 100 off the annual subscription (original price $ 250) for the first 50 customers (currently 43 left). Location specific discount is available. This includes access to all lessons and courses (free & paid), and access to future members only features such as download videos for offline viewing.

If this is something that interests you, go to https://composables.com/pricing and find the Annual plan and click on Subscribe.
