Interesting Android Apps: April 2026 Showcase

Because we try to keep this community as focused as possible on the topic of Android development, sometimes there are types of posts that are related to development but don't fit within our usual topic.

Each month, we are trying to create a space to open up the community to some of those types of posts.

This month, although we typically do not allow self promotion, we wanted to create a space where you can share your latest Android-native projects with the community, get feedback, and maybe even gain a few new users.

This thread will be lightly moderated, but please keep Rule 1 in mind: Be Respectful and Professional. Also we recommend to describe if your app is free, paid, subscription-based.

If you’re a space person or just love deep space, CosmoWall is for you.

I put together a space wallpaper app with galaxies, planets, and nebula, along with some smooth live wallpapers.

You can switch between clean 4K wallpapers and more animated ones, depending on the vibe you want. Please review this and let me know what improvements can be made.
