you have no knowledge?Breh How long would it take me to learn how to build my own cross platform app with very little knowledge?
if so it might take 6 months(optimistic)- 1 year(realistic)
for starters I'm assuming you're talking about building an app for iOS and android.
you would have to know swift programming for apple
java or kotlin for android
there's also flutter that lets you build apps for both ios and android
learning these languages could take 3 months if you make it a goal.
then you have to practice building apps for it.
depending on what the features of the app are it will change the timeline a bit
there's also app studios that build the app for you but they can be expensive.
