Difference between desktop, web and mobile apps

there are many differences, but the most prominent are that they have different apis (aplication programing interface) and different architecture

also mobile apps tend to use less system resources and are more regulated by services like the google play store, opposed to the fairly unregulated uwp platform used by most windows machines.  

try a gofundme or ask your family for money slowly and slowly then save it or do trades on craigslist. that's all i know
