What's the best Android app to turn my phone into a wireless charger for other devices?

Wireless Reverse Charging is a utility app designed to enable a phone's dormant reverse wireless charging capability, commonly known as power sharing. This is particularly useful for individuals who need to top up a pair of wireless earbuds, a smartwatch, or even another phone in a pinch, but whose device manufacturer may not have exposed the feature in the standard settings menu. The app provides a simple toggle and often includes diagnostic tools to check if a device's hardware supports the function.

Real-world testing indicates its primary utility lies with older or mid-range Android models that possess the necessary hardware (like a Qi transmitter) but lack a software switch. For example, someone with a Samsung Galaxy S10e could potentially use it to charge a friend's dying phone during a commute. However, user reviews consistently stress that success is not universal and hinges entirely on specific device compatibility; the app cannot magically add hardware that isn't present. Some users report frustration with phones that show as 'compatible' but fail to initiate charging, pointing to deeper driver-level limitations. The interface is straightforward, though a bit dated, and the developer clearly states it's a tool to unlock an existing feature, not a guarantee.
