Other texturing app aside from procreate?

i need another way to texture my models and keep the painting from the model and or make a uv map of my colors and save them

Next update will have bake to texture. For now if you have access to a PC you can use blender to bake. There is another app for iPad called ArnorPaint. It does texture painting but I warn you it is not good (yet). Search the forum for reviews.

do you know when the next update will be released?

No, but it will be worth the wait.
