Introduction

Advanced Android File Transfer Application for macOS.

Transferring files between macOS and Android or any other MTP devices has always been a nightmare. There are a few File Transfer MTP apps which are available online but most of them are either too expensive or come with bad UI/UX. The official "Android File Transfer" app for macOS from Google comes with bugs, innumerable limitations, some of which include - not being able to transfer files larger than 4GB, frequent disconnections, unable to rename the folders or files on the android/MTP devices. Most of the other apps available online uses either WiFi or ADB protocol to transfer the files, which is an extremely time-consuming process.

Countless searches to find an app to solve these problems and failing to find one made me restless. So, I took the leap and decided to create an app for us that could help us have a smooth and hassle-free file transfer process from macOS to Android/MTP devices. Created with the objective of giving back to the community, we can all use this app for free in this lifetime.
