Phone Doctor is a free app for mobile devices. It provides a collection of tools for the purpose of improving the performance of phones, in particular, phones that are aging and losing performance over time. These tools are geared towards things like cleaning junk from the phone's memory and battery-saving features.

The app is a phone utility, much like MyPhoneExplorer or UltData - iPhone Data Recovery. It provides functionality for managing and maintaining the device rather than entertainment or other functionality. The developers claim the app can improve battery life, performance, and more.

Keep the device running smoothly

Phone Doctor includes several tools that can be used to improve the performance of a phone. As a phone gets older and is used frequently, it will start to slow down. Phone Doctor can help mitigate the degradation of performance by making it easier to do things, such as clear out junk data that is no longer needed.

Improve battery performance

In addition to being able to clear up junk data, Phone Doctor also claims to be able to improve the battery life of the device. Part of this is an inherent result of improving the performance, as the phone will use less battery if the hardware is not working as hard. It also includes a Smart Power Manager.

A useful tool for older mobile devices

Phone Doctor is likely not going to offer much of an improvement on newer phones. Still, older phones that have started to slow down over the years may benefit from the app's optimizations and clean-up functions. There is also a specific feature for cleaning up WhatsApp data.
