[Advice and guidance for my daughter]

Affinity Photo is a Pixel-based image editing software, just like photoshop.

Affinity Designer is a vector-based graphic design software, just like illustrator.

Firealpaca is a pixel-based free digital painting software, it doesn't runs on Android devices, only available for Windows and Mac OS.

Medibang paint is similar to firealpaca and compatible with android,ipad,  window, and mac computers.

This is a good tip!  I've seen a lot of new websites lately that do conversions for all sorts of proprietary files, so this is yet another cheap option for those who don't own PS.  If I may, another option, which works so closely with PS, but you don't have to worry about high subscription costs, is the Affinity suite.  Affinity, based in the UK, created Adobe-type products that mimic the aforementioned so well that whether you are coming from Adobe products or are a first-time user, you won't have trouble getting up and running.  Another great point to make is that all modules from Affinity are a one-time license payment, meaning that they adhere to a perpetual license system, instead of monthly/yearly subscriptions.  Each module is reasonably priced and as for what you get with it, I still have yet to find a file format that Affinity has trouble with. I have a XP-Pen Star G640 drawing pad . and it  is working perfectly with photopea for photo editing .

Anyways, thanks again for the tip and if there is interest in Affinity, it is a cheaper alternative with less stumbling blocks.
