I needed to do some testing across a number of android phones and realized what a pain it was to mount/unmount and transfer the .apk over usb.

I figured I'd put a quick and dirty uploader on my network server that generated a qrcode link from each .apk i sent it. I did, and it saved a ton of time, so I cleaned it up and put it up for anyone to use here:

Upload your .apk and it returns a qrcode that directs to the .apk for downloading. The .apk files are cleaned off the server every 24 hours, and the qrcodes are not cached.

Hopefully someone finds this helpful for multiple device testing.
