Essential app for me – Smart Memory Pro - Check RAM & System Checker Review
iPhones 4s it cleans memory and also disk space. Now also useful with iOS 10.3.1 on iPhone 7 Plus.
Increasing the Max in settings recovers more memory.
I find it particularly useful when updating apps.
Note that scanning memory can reset other apps currently being run.
