Smart Optimizer is a free utility and tool application on the Android platform developed by Wonderful Apps Limited. The app aims to help users find and delete unnecessary and temporary files and clean their phone storage.

Smart Optimizer lets users quickly delete unnecessary screenshots, manage apps, and increase the device score. The app provides an easy-to-use interface that allows users to quickly scan and delete no longer-needed files, freeing up valuable space on their phones.

However, it is worth noting that the app requests users to contact the developer by email for any questions, bugs, or suggestions instead of using the market comment section. This may be inconvenient for some users who prefer to leave feedback directly on the app store. Overall, Smart Optimizer is helpful for those looking to optimize their phone's storage and keep it running smoothly.
