Recently iMovie updated to iOS 16 and if you are using iPhone 7 and 7 Plus will be noticed that you are unable to Install but the main point is whether iMovie still working or not after updated for iPhone 7 and 7 Plus
Unlike other apps like iMovie, Garageband is also in the iOS 16 list I know not only iPhone 7 & 7 Plus iPhone 6s, and 6s Plus users also face this issue same as these iPhones stuck right now on iOS 15.7.4

Can we able to Install it
if you are using any iPhone that is running iOS 15.7.4 can able still install it only if you have purchased it before otherwise, it is most likely impossible to do so however others who already purchased can use it as long it works I don’t you face any issue with your iPhone for now
One thing that you should know about the apps is that most of the basic apps are on iOS 14 and you will not face any issues more likely you can install it as there is a compatibility mode exists to help you to install apps on your iPhone 7 and 7 plus

What do if you have not Installed it Before
if you have not installed iMovie before it is really impossible now to install it as requires iOS 16 you need to have multiple iPhones that support iOS 16 make sure you use the same Apple ID with your iPhone 7 and 7 Plus try to Install on your other iPhone than you can able to Install it
