Free space defragmentation PRO

This application is the pro version of Free space defragmentation, so basically is the same application (the main goal is to speed up your device by defragmenting), but it's more performant.
The differences between them are that pro has:
- no ads
- a faster way of finishing the job (3 times faster) and less battery drainage

Before you decide to buy this application, consider downloading and testing the free version first.
