Been trying it out for the last month. Like how speedy downloads are and slightly better app discovery. Wish it could have native package downloads/system updating. However, I wouldn’t use it as my sole “Linux software app”. Regardless love that it exists and continue to follow

It might be useful for new Linux users but I wouldn't call it an "app store" since it works with flatpak only.

Btw, there's Warehouse if you need some advanced features and you prefer working with GUI - https://github.com/flattool/warehouse
