I have just used it on my Android phone so far, now I want to switch to iphone. I am not even sure if PicsArt supports it on iOS?

Theres a version of PicsArt for iPhone,  just search in the App Store for picsart.

You just need to search it on AppStore, previously I also used PicsArt for Android with picsart mod apk version at TechBigs, Gold membership package is free to unlock, unfortunately it only supports Android, I have not found any Any mod that supports IOS.

You can still use picsart, but you can no longer experience picsart gold mod apk on android. You should still have an Android phone.

No worries! Picsart is now available for iOS as well.

PicsArt is available for Android, iOS, and as a Windows Univeral app for mobile and desktop; I tested it on my iPhone 6s. Further more you can check details about iOS Picsart apk at thepicsartapk.
