DeltaTouch is one of my favorites in the Open Store. It’s the perfect way to replace any messaging app. There are also excellent DeltaTouch apps for iPhone and Android. It’s hard to convince parents and kids to use DeltaTouch. That’s because WhatsApp has integrated “Channels” into its app since 2023. What are “Channels”? They’re kind of like OnlyFans for kids and teens.

About the state of Frameworks and Game Engines: Unity: There is a Demo App in the store that prints FPS. Godot: There is also a kind of benchmark-like Demo App. Bacon2D: works, but is unmaintained for 8 years now. I believe that anything based on SDL or WebGL (or Qt) should do. Providing SDL3 with better system integration is in the works. Clickable provides a Godot app template, but this is for UT 20.04 currently. 24.04 support probably comes after beforementioned SDL3 (+SDL2 via compat layer) support is finished.
