Picuki has its detractors, even among those who are familiar with it. Those who believe this app and website are fake are not to blame. You won't have to worry about breaking the law if you use it to download Instagram photographs and videos. It's not quite as good as Instagram, but it's not terrible either. The picuki Instagram viewer app only allows you to view and update profiles, followers, and news for as long as you like. Nothing else is permitted for nothing.
